Welcome to Breathing Earth. This real-time simulation displays the CO2 emissions of every country in the world, as well as their birth and death rates.
Please remember that this real time simulation is just that: a simulation. Although the CO2 emission, birth rate and death rate data used in Breathing Earth comes from reputable sources, data that measures things on such a massive scale can never be 100% accurate. Please note however that the CO2 emission levels shown here are much more likely to be too low than they are to be too high

50 Way GO Green!!!!

If you can’t afford a new home or a large remodeling project, there are still plenty of things you can do to be environmentally friendly and save money.

1. Update your lighting
Make it a policy to buy energy efficient compact fluorescent light bulbs. You can now get a variety of shapes and perfectly match the color hue and lighting for each room. They look good and use at least two-thirds less power than regular lighting.

2. Buy Energy Star
When you are ready to buy new home appliances, buy smart. Check for the Energy Star rating. These more efficient machines can reduce your utility bill as much as 30-percent. Deb Snoonian, Managing Editor of Plenty Magazine said, “Energy Start is a program sponsored by the EPA and the Department of Energy. Essentially, it’s a way for them to recognize the companies and the products that are most energy-efficient. On average, an Energy Start appliance — whether it’s a computer monitor, a refrigerator, a washer or dryer — is going to be about 30-percent more energy efficient.”

3. Wall Warts
Those clunky power adaptors draw energy from the wall all the time. Unplug them individually or attach them to a power strip and turn off the whole switch when not in use. Around 75-percent of all electricity in a home comes from appliances that are turned off, but are still plugged in. Make sure that you only have those appliances plugged in where you’re actually using the electricity. You will save on bills and we as a society will save on energy.

4. Dormant Appliances
Practically every appliance uses electricity even when it’s switched off. Unless it needs power to retain programming memory, hit the switch. Better yet, make it a family practice. Amy Schachter, an Upper East Side resident, said, “My family reminds each other constantly. That’s partly money, partly the fact that we know now that we’re creating energy usage that is totally unnecessary.”

5. Energy Audit
You can find out how much energy your home uses each year with an energy audit. Many utility providers and state energy departments will audit your home free or at low cost to help you find ways to be more energy efficient.

6. Insulate
Make sure your ducts are properly insulated and install weather-stripping around windows and doors for a better seal. Tax credits on efficiency-increasing heating and cooling equipment make now a great time to upgrade. And remember, insulation pays for itself year round. Cascio Construction President Michael Cascio said, “It translates into the heat or the air conditioning that you’re going to use, and certainly you want to retain whatever heating system or whatever cooling system you’re using, you want to retain that inside the house.”

7. House Plants
Invest in large, live houseplants that will help keep your indoor air fresher.

8. Save Water
Place a water bottle filled with liquid or pennies into your toilet’s water tank. This will cause the tank to use less water every time you flush. Plenty Magazine Managing Editor Deb Snoonian estimates it wil save you about a quart to half a gallon per flush.

9. Solar Water Heater
Consider eventually installing a solar hot water heater on your property. It would cost about $8,500 for a family of four. You can apply for federal and state tax credits, which adds up to almost 50-percent. It’ll take about six and a half years for the system to break even on its investment, then you’re making free hot water.

10. Green Power
Many utility companies offer renewable energy products that can be purchased as a percent of total energy use or in blocks of kilowatts. Buying green energy helps support the development and use of renewable fuel souces.

There are few things you can’t turn into something environmentally friendly while making your pocket a little greener in the process.

11. Make Your Own Cleaning Supplies
Using simple ingredients such as baking soda, soap and vinegar, you can make cheap, easy, and non-toxic cleaning products save money, time, and your indoor air quality. This is especially important if you have kids, pets or if there are elderly people in your home who are sensitive to chemicals in the air so you and your home will be healthier.

12. Safer Paint
Paint can be made with the same volitile organic compounds found in nail polish or gasoline. Major manufacturers and some boutique brands have introduced low VOC paint. It spreads, it covers and leaves the room smelling just fine.

13. Aerosols
Limit your use of aerosol cans. Because they have limited recycling value, the containers will probably wind up in a landfill. Instead of aerosols, look for spray bottles, liquids, powders and roll-ons.

14. Cloth
Paper towels and napkins can be made from recycled paper, though in some cases the recycling costs more than making a brand new product. You won’t hear that about cloth napkins, which can be washed and re-used again and again.

15. Laundry Room
By making sure your lint filter is clean and your dryer exhaust free to open and close, you are essentially tuning up the efficiency of your appliance. It will run better and be more cost efficient.

16. Air Dry
For the ultimate in low cost laundry drying, put the clothes on either a drying rack or go outside and use the clothesline.

17. Smart Landscaping
Trees and shrubs provide shade during the summer and can help shield your house from frigid winter winds. Both can help lower your energy bill.

18. Walking the Dog
Instead of plastic bags, scoop your doggie’s doo in biodegradable bags.

19. Compost your leftovers
Composting helps reduce the amount of waste you send to the landfill. In the process, you create free, healthy fertilizer for your garden.

20. Collect the Rain
Place a barrel under a gutter downspout and let it fill over time. Plenty Magazine Managing Editor Deb Snoonian said, “Rain water is actually healthier for plants and gardens than tap water which often has chlorine in it to kill bacteria, but bacteria can inhibit plants from growing.

Green at home is one thing; green at the office has its own set of special challenges. Going green is a lifestyle choice, not just a home activity. So what are some steps you can take at work to make things more environmentally friendly?

21. Buy a laptop
Even an oversize laptop runs more efficiently and takes less energy than a desktop.

22. Reduce Paper
The paper trail follows many of us, adding hundreds of pounds of waste. You can reduce it with just a few changes. Save printing: send documents by email and keep files on your computer, not a filing cabinet.

23. Print Double Sides
You can save plenty of paper by programming your printer to use both sides of the paper. In the case of a long report, do you really need 500 one-sided pages?

24. Refill and Reuse Cups
“Many of us get take our coffee in the morning and were using plastic and cardboard cups,” said Plenty Magazine Managing Editor Deb Snoonian. “Bring your own mug. You can leave one at work; you can even often times bring a reusable mug as you’re commuting in your car. It can be refilled over and over again. Wash it at home it’s a nice habit to get into that saves you one cup a day.”

25. Pay Your Bills Online
It’s not only quicker and easier to pay by computer, it also puts a major dent in the paper waste pile.

26. Recycle Your Appliances
Not just the big ones. Cell phones, PDAs and laptops can all find a new purpose after you’re done with them. Many organizations refurbish them for low-income families.

27. Become Battery Smart
Stretch your battery use. A battery too drained to power a flashlight might be perfect to operate your TV remote. Before you pitch it – switch it!

28. Lights Out
Motion sensors, dimmers and timers can be set to turn things on and off when needed.

29. Going Grey
Ask your commercial building manager about using gray water tanks. It’s a system that recycles water from your building’s toilets, washing machines and dishwashers. Impractical? Don’t say that around New Jersey’s Aspen Ice Skating Rink where the septic water is collected, treated and put back on the rink. At this point, the systems are a bit too costly for one-family use, but if you’re in a commercial building or a planned community, consider making the water work for you.

30. Water
Speaking of water, instead of bottled water around the meeting table, filter your tap for drinking water. Not only is bottled water expensive, but it produces large amounts of wasteful containers.

Even if you can’t buy the most environmentally friendly car, there are still plenty of things you can do to get from one place to another with minimum energy. Getting to work, school and running errands all add to your energy budget. To go green you don’t have to give up transportation, just use it a bit more wisely.

31. Work From Home
Instant messaging and video conferencing now allow you to hold conferences or even take online classes. This means you save time and gas.

32. Use Public Transportation
Trains, buses, boats, car pools and your own feet.

33. Rental Car
When driving is necessary, use an inexpensive hourly rental car.

34. Drive Economically
Even if you can’t afford a fancy hybrid, there are plenty of cars that get great mileage. A car that gives you another 10 more miles to the gallon puts $1,000 dollars a year back in your pocket!

35. Drive Smart
Properly inflate your tires, change your air filter and drive 55 mph on the highway.

36. Friendly Fuels
Using bio fuels goes way beyond ethanol. Look for environmentally friendly oil car fluids and, of course, read how to use and dispose of them properly.

37. Car Air Conditioning
It’s practically standard on modern cars. Use it wisely. At higher speeds, open windows create drag and lower your mileage. Roll them up and use the air and recirculation. At slower speeds and around town, roll down your windows and catch a cool breeze.

38. One Right Turn Deserves Another
The time spent in your car idling while waiting to turn against oncoming traffic burns fuel and costs millions each year. In metro New York, United Parcel Service (UPS) reduced emissions by 1,000 metric tons with a software map program customized for every driver to minimize lefts.

39. Drive Thru
Avoid the drive thru. Instead of idling in line with your engine running for several minutes, save the gas by parking and going inside for your order.

40. Car Wash
Commercial car washes can be more efficient than home washing. Check to make sure that they clean and recycle the water.

In the store, in your home, even while you sleep…There are things you can do to be more energy efficient and better to the environment.

41. B.Y.O.B.
Bring Your Own Bag. Some grocery stores give you cash toward your next purchase for every bag you bring in to use again. It saves them and you money. “In the U.S., we use five hundred billion plastic bags every single year and only three percent of those get recycled,” said Deb Snoonian, Managing Editor of Plenty Magazine. “You can also buy permanent bags with designer colors.”

42. Packaging
Check the amount of cardboard, plastic and other materials used for the box. Some retailers are replacing plastic containers with corn-based packaging.

43. Buy Big
By purchasing things in larger quantities, you will probably save money and certainly save the cost of packaging and transporting smaller boxes of the same thing.

44. Green Fashions Are Becoming Hot
Look for clothes and accessories like handbags that are environmentally friendly.

45. Pet Products
Even kitty litter can be laced with questionable ingredients. Look for natural alternatives.

46. Antiques
Antiques are sort of the ultimate recyclable, servicing generations of owners. Many can be restored with natural wax products at a very reasonable price.

47. Buy Water Efficient Showerheads and Aerators
Many modern showerheads are built to conserve. Check to see how well yours works. Also, aerators on the faucets will keep water waste to a minimum.

48. Mattresses
Federal regulations will soon require all sleeping mattresses to be fire resistant. If you like the safety but don’t care for the flame retardant chemicals, some popular brands are introducing models with a more natural fiber based flame retardant barrier.

49. Energy Offset Certificates
These essentially allow you to invest in an environmentally friendly cause.

50. Smart Recycling
Smart recycling can be environmentally sound and pleasing, too. Companies like IceStone make durable surfaces made from recycled materials, like glass and concrete. Recycling is not limited to bottles. Used doors windows, fixtures can all be bought at a fraction of the new price. Think creatively – a New York man built a veritable castle of recycled materials.

Asap kendaraan bermotor dan pabrik di Jakarta membuat wilayah Ibu Kota sangat miskin udara bersih. Alhasil, terjadi kerusakan lingkungan dan asap tersebut membahayakan kesehatan.

Maka, pada 2000, Gubernur DKI Jakarta Sutiyoso menelurkan Surat Keputusan Nomor 95 tentang Pemeriksaan Emisi dan Perawatan Mobil Penumpang Pribadi di Provinsi DKI Jakarta. Pengawasan terhadap emisi juga dilandasi Undang Undang Nomor 22 Tahun 2009 tentang Lalu Lintas Angkutan Jalan.
Undang-undang mengharuskan setiap kendaraan yang berjalan beremisi baik.

Ada lagi Undang-Undang Nomor 32 Tahun 2009 tentang Pengendalian Pencemaran Lingkungan, yang mengatur sanksi pidana bagi pelanggarnya. Menurut Pasal 98 Ayat 1 Undang-Undang Pengendalian Pencemaran Lingkungan, orang yang menyebabkan pencemaran yang melebihi batas dipidana penjara 3-10 tahun dan denda Rp 3-10 miliar.

Menurut Hotman Silaen, Kepala Kantor Lingkungan Hidup (BPLHD) Kota Jakarta Utara, emisi adalah gas buang dari sumber kendaraan bermotor sebagai hasil proses pembakaran di ruang mesin. Pengendalian emisi tidak hanya dilakukan pada mesin bergerak, tapi juga mesin tak bergerak, seperti mesin pabrik. Bersama BPLHD DKI Jakarta, uji emisi rutin dilakukan terhadap industri, terutama di Jakarta Utara, minimal enam bulan sekali.

Berpegang pada aturan tersebut, Hotman menggelar sosialisasi uji emisi. Pada 2 November lalu, BPLHD bersama Polres Jakarta Utara mengadakan uji emisi gratis di lapangan Balai Kota Jakarta Utara.
Lalu, pada 5 November 2009, diadakan acara serupa di Jalan Yos Sudarso, tepatnya di depan Depo BBM Pertamina Plumpang. Hasil uji emisi kedua, dari total 202 mobil pribadi dan angkutan umum, 115 kendaraan berbahan bakar bensin (92 lolos) dan 87 berbahan bakar solar (31 lolos).
“Tingkat emisi kendaraan di Jakarta sangat buruk,” ujarnya akhir pekan lalu kepada Tempo Gading.

Warga Kelapa Gading menanggapi secara beragam aturan yang berlaku mulai 1 November 2009 untuk mobil dan awal tahun depan untuk sepeda motor itu. Giovanni A. Widjaja, 33 tahun, menduga aturan itu sulit dijalankan. Ia mencontohkan, aturan KIR pada angkutan umum juga tak dilaksanakan dengan baik.
“Apalagi mengawasi mobil pribadi, yang jumlahnya jauh lebih banyak.
Siap nggak petugasnya?” kata principal sebuah broker properti kondang di Kelapa Gading itu pekan lalu.

Rentetan gempa besar di pesisir barat Sumatera dan selatan Jawa meninggalkan misteri di Selat Sunda, yang terletak di antara kedua pulau itu. Ketika daerah lain sudah berderak dan berusaha menyeimbangkan diri dengan cara melepaskan energi impit-impitannya, palung di selat ini seperti diam dan terkunci.

Secara kasatmata, selat itu seperti “dilompati” begitu saja oleh rentetan gempa besar.

Dalam orasi ilmiah pengukuhannya sebagai profesor riset bidang geologi-geofisika, Jumat lalu, Deputi Kepala LIPI untuk Ilmu Pengetahuan Kebumian Hery Harjono menjelaskan bahwa Selat Sunda bukan sekadar perairan yang memisahkan Jawa dan Sumatera. Selat itu terletak pada perpindahan subduksi tegak lurus ke subduksi miring.

Diduga, lempeng Indo-Australia yang menghunjam di bawahnya mengalami deformasi sedemikian kuatnya sehingga jadi sobek. Kalaupun tidak sobek, lempeng yang menghunjam di bawah Selat Sunda dalam keadaan tertekuk dan menimbulkan kelurusan gempa berarah U50T (timur laut).

Selat Sunda dan sekitarnya mengalami ekstensi sebagai akibat pergerakan lempeng mikro Sumatera ke arah barat laut sejak masa Ogliosen Atas (28 juta tahun lalu). Diduga sebelum masa ini Jawa-Sumatra masih membentuk garis lurus atau tumbukan antar lempeng benua Indo-Australia dengan Eurasia di sepanjang palung Jawa-Sumatera yang masih tegak lurus.

Ekstensi menyebabkan penipisan kerak bumi dan menciptakan reservoir magma cukup besar di kedalaman lebih dari 20 kilometer di bawah kompleks Krakatau. Di atas reservoir itulah terdapat beberapa kantong magma yang dipasok lewat retakan-retakan.

Meski masih ada misteri di bagian palung, Hery menegaskan, secara umum Selat Sunda secara geologi sangat aktif oleh aktivitas kegempaan, gunung api, dan gerak tektonik penurunan yang cepat. Selat yang memiliki kedalaman tidak lebih dari 100 meter, kecuali di kompleks Krakatau yang bisa mencapai 200 meter, ini juga dihiasi morfologi graben alias lembah berarah utara-selatan, yang diperkirakan kelanjutan dari patahan Sumatera yang menerus sampai ke palung Jawa.

“Pembangunan mega-infrastruktur, seperti jembatan atau terowongan, di Selat Sunda tidak boleh mengabaikan kenyataan bahwa wilayah tersebut sangat aktif,” katanya.

Tanah telantar diambil negara.

— Menteri Kehutanan Zulkifli Hasan memastikan pihaknya akan merehabilitasi sekurang-kurangnya 500 ribu hektare hutan per tahun sebagai salah satu agenda besar kontrak kerjanya dalam lima tahun mendatang. Ia juga akan merehabilitasi 13 daerah aliran sungai di Jawa mulai awal 2010. “Seperti Brantas dan Bengawan Solo,” katanya saat memaparkan program 100 hari di kantornya kemarin.

Pengurangan pembakaran hutan, lahan gambut, maupun hutan alam juga masuk agenda lima tahun. “Sekurang-kurangnya 20 persen, ” katanya. Terutama, kata dia, menurunkan emisi di titik-titik biasa terjadi kebakaran hutan di Riau, Jambi, Kalimantan Tengah.

Sekretaris Jenderal Partai Amanat Nasional itu juga menyatakan tidak ada lagi pembangunan kehutanan tanpa melibatkan publik. Ia memastikan bakal ada keberpihakan kepada mereka yang selama ini dianggap terpinggirkan dalam pembangunan sektor kehutanan. Masyarakat di sekitar hutan, kata Zulkifli, harus merasakan manfaat alam, yakni hutan. Caranya, dengan meningkatkan hutan kemasyarakatan, hutan desa, hutan tanaman rakyat, dan hutan rakyat.

Agenda penting lainnya adalah menyelaraskan permasalahan tata ruang antara provinsi dan kabupaten. Saat ini banyak yang masih tercatat sebagai hutan lindung, tapi sudah jadi kantor bupati atau gubernur. “Dalam 100 hari akan dilihat dan diperbaiki serta akan dikeluarkan Perpu, sehingga peraturan kehutanan tidak tumpang tindih,” katanya.

Sementara itu, Badan Pertanahan Nasional (BPN) akan menertibkan 7,13 juta hektare tanah telantar dan mengalokasikannya untuk kepentingan negara tanpa ganti rugi. Hal itu sesuai dengan Undang-Undang Pokok Agraria bahwa semua tanah dapat diambil negara apabila dibiarkan telantar.

“Akan diperuntukkan bagi cadangan negara untuk kepentingan strategis, seperti pangan, energi, dan perumahan rakyat,” kata Kepala BPN Joyo Winoto dalam pertemuan dengan Menteri Negara Perumahan Rakyat Suharso Monoarfa dan pengurus Kamar Dagang dan Industri (Kadin) di Jakarta, Ahad malam lalu.

Ia menerangkan, tidak semua tanah yang telantar adalah tanah tanpa pemilik. Tanah-tanah ini bisa jadi setelah tiga tahun atau lebih tak pernah dikelola. Jika dalam tempo sebulan setelah peringatan para pemilik tanah tidak merespons, kata Joyo, hak kepemilikannya akan dicabut.

Negara-negara berkembang kemarin berkeras agar upaya mengikat secara hukum traktat perubahan iklim bakal terwujud dalam Konferensi Tingkat Tinggi Perubahan Iklim di Kopenhagen, Denmark, bulan depan. Padahal Presiden Amerika Serikat Barack Obama dan sejumlah pemimpin dunia lainnya menganggap hal itu belum mungkin terlaksana.

“Kami percaya kesepakatan untuk mengikat secara hukum masih mungkin,” ujar Menteri Lingkungan Grenada Michael Church, yang mengaku mewakili 40 negara yang tergabung dalam Aliansi Negara-negara Kepulauan Kecil tersebut. Church optimistis, sedangkan Duta Besar Sudan untuk Perserikatan Bangsa Bangsa –Lumumba Di-Aping – pesimistis.

“Kita jalan di tempat,” ujar DiAping, yang mengaku mewakili negara-negara sedang berkembang di Grup 77 dan Cina. Tengok saja pernyataan tuan rumah, Denmark. “Waktunya amat sangat terbatas untuk merangkum seluruh kesepakatan,” ujar Menteri Lingkungan Denmark Troels Lund Poulsen.

Maklumlah, di Kopenhagen akan datang lebih dari 40 menteri lingkungan yang cuma punya waktu berunding selama dua hari. Itu belum seberapa. Isu pemangkasan gas rumah kaca dan jumlah dana bagi negara-negara miskin juga masih jadi kendala untuk bersepakat. Itu mengemas traktat perubahan iklim masih jauh panggang dari api.

“Saya akan ke Kopenhagen bilamana kehadiran saya berarti bagi adanya kesepakatan yang penting,” ujar Presiden Obama dalam kunjungannya ke Konferensi Tingkat Tinggi Kerja Sama Ekonomi Asia-Pasifik (APEC) di Singapura. Obama termasuk yang menyokong pembahasan kesepakatan hukum tentang perubahan iklim itu ditunda hingga 2010. Komentar Obama ini mengundang kecaman dari juru kampanye iklim Greenpeace, Joss Garman. “Sudah 12 tahun semenjak Protokol Kyoto dan dua tahun dari negosiasi di Kopenhagen, tapi Obama bilang masih butuh waktu untuk bicara?” ujarnya. “Dunia tak bisa mundur dan menundanunda lagi.”

Boleh jadi Garman ada benarnya. Tengok saja hasil riset kelompok konservasi alam internasional, WWF , Ahad lalu. Kata WWF , Dhaka, Manila, dan Jakarta adalah kota-kota utama di Asia yang rentan terhadap bencana akibat perubahan iklim dunia. “Rentan terhadap gelombang pasang air laut, badai, dan dampak perubahan iklim lainnya,” begitu ujar WWF .

Jakarta dan Manila (Filipina) disebut amat rentan lantaran ukuran dan seringnya terkena banjir serta rendahnya kemampuan beradaptasi. Dalam laporan bertajuk “Mega-Stress for MegaCities” itu disebutkan sejumlah kota lainnya yang juga rawan, antara lain Kalkuta, Phnom Penh, Ho Chi Minh, Shanghai, Bangkok, Hong Kong, Kuala Lumpur, dan Singapura.

“Kota-kota besar mengkonsumsi 75 persen energi dan bertanggung jawab atas jumlah emisi karbon dioksida yang sama yang menyebabkan pemanasan global,” kata Nicholas Stern, bekas Kepala Ekonomi Bank Dunia yang pernah menulis kaitan ekonomi dengan perubahan iklim pada 2006. “Perubahan iklim bukanlah perubahan di dalam air semata.”

Dan, seperti diungkapkan WWF, Asia, yang padat populasinya, adalah benua yang paling rentan terhadap perubahan iklim itu. Kalau jalan-jalan utama tergenangi air akibat banjir, akankah transaksi ekonomi berjalan mulus? Akankah tumbuh-tumbuhan bisa dipanen di pengujung musim?

Panel Antar Pemerintahan untuk Perubahan Cuaca (Climate Change) , dalam laporannya, menyebutkan terjadinya peningkatan gas karbon dioksida (CO2) di atmosfer. Bersama gas-gas rumah kaca lainnya, CO2 menjadi biang keladi perubahan iklim. Hutan bakau (mangrove) ternyata mempunyai kemampuan menyerap gas tersebut.

Hal ini ditunjukkan oleh Nyoto Santoso dalam risetnya di Batu Ampar, Kalimantan Barat, pada 2007.  Nyoto mencatat bahwa bakau dengan kondisi baik mampu menyerap karbon sebesar 10,68 ton/hektare/tahun. Penelitian lain dilakukan oleh Ball– seperti dikutip oleh Sukardjo (1996)– yang menunjukkan bahwa fotosintesis bakau secara khas terpenuhi mencapai ½-2/3 dari seluruh radiasi sinar matahari. Lalu mempunyai suhu optimum di bawah 35 derajat Celsius dan memiliki titik kompensasi CO2 yang mudah ditera. Pada kondisi normal, keseimbangan CO2 secara linier berhubungan dengan daya hantar listrik daun.

Menurut Ball, kecepatan asimilasi banyak berkurang pada suhu daun yang tinggi. Pada beberapa jenis bakau, kecepatan asimilasi relatif tidak terpengaruh oleh suhu dengan kisaran 17-30 derajat Celsius, melainkan menurun secara tajam pada suhu di atas 30 derajat Celsius dan mendekati nol pada suhu 40 derajat Celsius.

Selain peredam CO2, bakau memiliki fungsi lain. Davis, Claridge, dan Natarina mencatat sejumlah manfaat itu.

  1. menjadi habitat satwa langka, seperti 100 jenis burung, termasuk burung langka Blekok Asia.
  2. melindungi bangunan, tanaman pertanian, atau vegetasi alami dari kerusakan akibat badai atau angin yang bermuatan garam melalui proses penyaringan.
  3. pengendapan lumpur, sehingga kualitas air laut terjaga dari endapan lumpur erosi.
  4. penambah unsur hara.
    penambat racun.
  5. sumber alam dalam kawasan (in-situ) dan luar kawasan (ex-situ).
  6. transportasi.
  7. sumber plasma nutfah.
  8. tempat rekreasi dan pariwisata.
  9. sarana pendidikan dan penelitian.
    memelihara proses-proses dan sistem alami.
  10. penyerapan karbon.
  11. memelihara iklim mikro.
  12. mencegah berkembangnya tanah sulfat masam.

Tidak hanya itu, buah dan daun bakau dapat diolah menjadi bahan baku beragam makanan kecil, sirop, dan urap.
Berdasarkan penelitian Departemen Kelautan dan Perikanan, buah bakau mengandung gizi seperti karbohidrat, energi, lemak, protein, dan air. Karbohidrat yang terkandung di dalamnya mencapai sekitar 76,56 gram per 100 gram.
Buahnya mengandung senyawa yang bermanfaat bagi tubuh manusia, seperti monosakarida, terutama glukosa, galaktosa, dan fruktosa.
