The Importance of the Earth's Rainforests

julesrs007
Tropical rainforests are a world like none other; and their importance to the global ecosystem and human existence is unequivocal. Unparalleled in terms of their untold biological diversity, tropical rainforests are a natural reservoir of genetic diversity which offers a rich source of medicinal plants, high yield foods, and a myriad of other useful forest products. They are the world’s richest and most productive ecosystems, containing half of all living species on the planet and a multitude of unique indigenous cultures.

Tropical rainforests play an elemental role in regulating global weather in addition to maintaining regular rainfall, while buffering against floods, droughts, and erosion. They store vast quantities of carbon, while producing a significant amount of the world's oxygen.

Despite their monumental role, tropical forests are restricted to the small land area between the latitudes 22.5° North and 22.5° South of the equator, or in other words, between the Tropic of Capricorn and the Tropic of Cancer. Since the majority of Earth's land is located north of the tropics, rainforests are naturally limited to a relatively small area.

Tropical rainforests, like so many other natural places, are a scarce resource. The vast swathes of forest, swamp, desert, and savanna that carpeted Earth's land surface a mere five generations ago have been reduced to scattered fragments; today, more than two-thirds of the world's tropical rainforests exist as fragmented remnants.

Just a few thousand years ago, tropical rainforests covered as much as 12% of the land surface on earth, or about 15.5 million square km, but today less than 5.3% of Earth's land is covered with these forests (about 6.7 million square km).

The largest unbroken stretch of rainforest is found in the Amazon river basin of South America. Over half of this forest lies in Brazil, which holds about one-third of the world's remaining tropical rainforests. Another 20% of the world's remaining rainforest exists in Indonesia and Congo Basin, while the balance of the world's rainforests are scattered around the globe in tropical regions. (Adapted for educational purposes from mongabay)

The Disappearing Rainforests

We are losing 33,8 million acres of tropical forest per year, that’s 500,000 trees every hour, or an area the size of a football field every second!

The Amazon covers over a billion acres, encompassing areas in Brazil, Venezuela, Columbia and the Eastern Andean region of Ecuador and Peru. It is the most diverse ecosystem in the world, supporting around 60,000 plant species, 1000 bird species and more than 300 mammal species. The rainforest is also home to 20 million people.

Over the past 30 years 15% of the Brazilian Amazon has been completed destroyed - that's an area the size of France. In 2002 an area the size of Belgium was destroyed, the second highest figure on record.

There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less than 200,000. In Brazil alone, European colonists have destroyed more than 90 indigenous tribes since the 1900's.

Why do tropical forests disappear?

Logging is one of the principal causes of destruction in the Amazon. By building roads in pristine forest, the logging industry opens the door to further devastation such as clearing forest for cattle ranches and soya plantations. When the demand in the world for meat increases, more rainforest lands are being destroyed and turned into farmland for animals.

Tropical forests yield some of the most beautiful and valuable woods in the world, such as teak, mahogany, rosewood, balsa, sandalwood, and countless lesser-known species.

Most of the rainforest timber on the international market is exported to rich countries. There, it is sold for hundreds of the times of the price that is paid to the indigenous peoples whose forest has been plundered. The timber is used in the construction of doors, window frames, crates, coffins (we consume even in death!), furniture, plywood sheets, chopsticks, household utensils and other items.

    • All the more reason to know where your forestry products come from... just take a look at the way Indonesian firms are burning and hacking apart precious rainforest to pave the way for palm oil plantations to supply huge corporations like Nestle (think Kit Kat bars, PowerBars, Nestle Quick, etc) with palm oil for their products.

      We need to make targets out of companies like Nestle for sourcing palm oil in places like Indonesia -- places that are still lucky to be blessed with rainforest. If that means boycotting their products, then we have to do that to protect the rainforest. But in terms of online activism, here's a petition targeting the CEO of Nestle on this very issue, check it out: http://bit.ly/cKxYTI

    • Regardless of the fact that some people will find the statistics in a piece like this to be inflated, or invented, a look around with our own eyes makes it impossible to deny that humanity is, as they often have throughout history, having a negative effect on the environment - and that people in third world or developing nations are exploited. An unfortunate part of human nature is that societies as a whole seldom change unless its of financial benefit or a direct and overwhelming threat to them. These things are real. We can all agree to disagree on the statistics if we want to, but I think we loose sight of the big picture when we focus on that too much. Good post.

    • So you posted this so everyone would go ga-ga over saving rain forests and forget all about drilling for oil in the Arctic Wilderness National Refuge and offshore drilling?

      And exactly how are you privy to Al Gore's stock portfolio, checking account or real estate assets? How about sharing with the rest of us how you became so knowledgeable?

      I think we need to protect rain forests. I think we also need to protect Arctic Tundra. And swamps and wetlands. And prairies. And temperate and boreal forests. And marine environments.

      We protect natural habitats from encroaching exploitation by making set aside protected areas. And we need to keep those areas protected.

      We need to protect all different kinds of environments. I agree drilling for oil needs to stop and the artic tundra needs attention, but this is just one story about one problem.

    • ...its like all these clowns have to do is show you a picture of a bulldozer with some trees knocked down behind it for effect...throw in some sad tale w/huge fabricated numbers 10,000 acres a DAY!!! ...

      add a few scary words like "GIANT CORPORATION!!!" or "SLASH & BURN!!!" and out you come with clenched fists full of cash and a heart full of Righteous Indignation. GET A CLUE. The bears aren't in danger...rube...WE are.

    • Tropical rainforests are a world like none other; and their importance to the global ecosystem and human existence is ...(see TRUTH below)

      ...no more or less than it was 10,000 years ago. All hype. it's about the money. It's ALWAYS about the money. Money for "researches" most of whom are no different than any other "charity" with the lions share of funding going into the pockets and offshore bank accts. of private individuals. Fear tactics. If they can make you afraid, if they can distract you with a boogie man to hate...it makes it easier to get your money out of your pocket into theres.

      "Lets CELEBRATE our bio-diversity! Let's strip off our clothes and run NAKED THRU THE RAIN FORESTS!!! (but watch out for the anacondas...they still think its a damn jungle)

      As a soldier/correspondent in south east asia...viet nam,cambodia, laos,burma I saw miles & miles of "rain forest" wiped out by Arc lights and arty barrages. completely defoilated by toxic chemicals (agent orange & worse). It was BACK 100% in two years. there may not have been as many 40ft tall trees...but some..and ALL the rest of it was there. right back like it was.

      Nui Ba Den ( the black virgin mtn in tay ninh province) was a prime example. in may of 69 we hit that mountain with everything we had. Heavy artillery rounds spun 50 ft tall trees and boulders of granite spiraling thru the air. Jets pounded it with napalm. arc lights (b-52 raids w/ 500 lb bombs) ripped craters in the sides of the mtn. At night we would watch the fires glow until dawn.

      This one particular operation went on for weeks. a joint op. with 1st cav, llth acr, special forces, 5th arvn abn...23 arty grp...

      When we started it was a 3200 ft tall mtn that jutted up from the "rainforest floor" all by itself. the only mtn in 3rd corp. It was granite base with lush green thick triple canopy in places, giant banana roots made it a bear to climb. When we got done only the very top...which was ours and we didn't bomb...and the very bottom were still green... the rest of the entire mtn was devasted...huge sections of gray granite with NO vegetation left on it. from a distance resembled a huge mangy dog. By the time I left that area not quite a year later...It was completely covered again in thick jungle growth. Trees were already topping out above the undergrowth...

      I saw pictures of this mtn 10 yrs later. It was completely recovered WITHOUT assitance from man. On its own. They made the thing into an amusement park complete with tram rides to the top and disney like animal statues along the sides. The old Cau Dai temple is still there...its as if it had never happened.

      Get off this fear and paranoia people. everything is okay. just a tactic of the powers that be seeking...mo money...more control more power. That jungle is fine....

      so next time some liar from some so-called govt. agency starts throwing out wild no.s like

      "50,000 sq. miles of rain forest a day are being destroyed!!!!...

      it's bull crap. You have no way to know if they are making it up entirely or just twisting the facts...so stop blindly believing people who have proven they cannot tell the truth...

      Don't be such a sap. Aren't you tired of being a stooge for these hacks? Think for YOURSELF. It's ALWAYS about the money. always. Its never about anything else...

      while you're franticaly running around scratching together pennies to SAVE the bears, or the air or the water or the eagles or the snail darters...or the oceans...Al big oil Gore is putting cocoa butter on ol tipper on his private beach in the bahamas. now when he gets low on cash or his baby wants a new beamer, he'll either sell off some more of his occidental petroluem stock...or go out and create another crisis, collect another 3 mil. and fly his jumbo jet back to the bahamas. what a gig.

    • Biodiversity means genetic adaptation. It has nothing to do with tropical rain forests. Biodiversity can be found in any type of environment, from tropical rain forest, to grasslands, to marine.

      The loss of habitat is the most major cause of species extinction. Regardless of habitat type.

      Rain forests are important. But they are no more or less important than any other habitat. Prairies, deciduous forests, coniferous forests, arctic tundra, deserts, swamps, marine environments, and even urban environments are just as important to biodiversity as rain forests.

      "Nature" is not something that only exists in a rain forest in Brazil or Indonesia-----nature is everywhere. Nature is being destroyed everyday to build suburbs and parking lots for strip malls.

      If you want to have biodiversity, you have to have protected habitats. Of all types. Not just rain forests.

    • I think more people have lost touch with nature. I remember being young and outside playing, getting dirty almost the entire day. We may not have understood all the things we saw in nature but it certainly planted the seed of curiousness. It may be a fluke but most of the kids I grew up with have nature-related careers and I have a few out of control hobbies.

      Maybe our group was just lucky. When I see the neighborhood some 20 years later the streets are usually empty of children. Society has also changed I feel. Parents are over-protective and it's easier for them to let the kids play video games and surf the net than take them to the park.

      In America we have a bad habit of praising popularity over academics and in the long run it's causing more damage than anyone expects.

      It would be a bleesing to see a revival of science in schools.

    • while this is happening people are to preoccupied with shopping, drinking, smoking, not giving a damn about themselves or their environment. i bet more then 50% of the population of this world even knows that deforestation is even a problem. they should be teaching this in schools not useless garbage just to keep us in school for 7 hours of the day.

    • What concerns me is that people are apathetic about what we are doing to the planet. These forest provide a carbon filter for the world and all of our pollution. Anyone who says that man is not impacting the planet in a negative way is intentionally ignoring the situation.

      It also concerns me that people are going to depend on scientist to come up with a cure for our planet. I think our commerce is doing more damage through industry to our planet than the world cares about.

      Al Gore's movie/documentary really opened my eyes with facts and the impact. We all have been following the progression of the polar ice caps melting. The ozone increasing in size. The warming of our planet is causing more moisture in the air and causing our storms, winters, and weather events to be magnified.

      Our habits are going to have to change, my fear is it that it will be too late to reverse the damage.

    • Sickening. Wiping out the rainforest has incredibly far reaching consequences for humans. Consequences that will eventually lead to, essentially, the drying up of our planet, the spread of more infectious disease (as a product of water not being properly filtered by the immense root and mycelial systems of the rainforest) ... and as far as biodiversity is concerned... nature has already found solutions for the problems that we're still creating. Very few organic compounds necessary for human life to continue can be synthesized in a lab. Alkaloids, fats, and other organic molecules produced by some herbs, mushrooms, and other plants & animals that we know of can cure (or help cure) some of our greatest ailments... and there are millions of species we're destroying before we even see them. Think of all the potential technological advancement, or advancements to medicine that we could be finding. We are a sick, sad race of barely-self-conscious bacteria, if you ask me.

    • When you purchase almost ANYTHING nowadays, food, clothing, furniture etc., some (or ALL) of the ingredients used to create the goods have most likely been imported from outside the US.

      Always look for the logo for certified "Fair Trade".

      WATCH-OUT! Do not get scammed with the "fairly traded", "traded fairly", "We support fair wadges" etc. bullsh*t.

      Deforestation gets the least amount of air time and is the Most important issue. Too often media rants against climate change, which is a distraction to the average person, who won’t necessarily associate it with deforestation. The media and others should stop railing against the climate and directly focus on environmental issues.

      I totally agree. It's terrible that climate change has been negatively and unfairly associated with the Democratic party. This is a highly conservative country that's unwilling to be informed due to a political bias. Why should infomation about our amazing world and it's troubles get lost in politcal theater? Science censored from textbooks and media is an increasingly common protocol. We're lucky the EPA still exists.

    • The Wealth of the Rainforests

      · More than half of the world's estimated 10 million species of plants, animals and insects live in the tropical rainforests.

      · One-fifth of the world's fresh water is in the Amazon Basin.

      · 30% of all bird species and 90% of all invertebrates are found in the tropical forest.

      · A single pond in Brazil can contain more kinds of fish than are found in all of Europe's rivers.

      · One tree in Peru had forty-three different species of ants, which is the estimated to be equal to the number of ant species in the British Isles.

      · At least 80% of the developed world's diet originated in the tropical rainforest. Fruits like avocados, coconuts, figs, oranges, lemons, grapefuit, bananas, guavas, pinapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.

      · At least 3000 fruits are found in the rainforests. Of these only 200 are now in use in the Western World. The Indians of the rainforest use over 2,000.

      · Nearly half of the world's species of plants, animals and microoganisms will be destroyed or severely threatened over the next quarter century due to Rainforest deforestation.

      · Experts estimate that we are losing 50,000 plant, animal and insect species a year. As the rainforest species disappear, so do many possible cures for life-threatening diseases.

      · Tropical forests have given us chemicals to treat or cure inflammation, rheumatism, diabetes, muscle tension, surgical complications, malaria, heart conditions, skin diseases, arthritis, glaucoma, and hundreds of other maladies. Forests offer stimulants, tranquillisers and contraceptives.

      · 25% of the active ingredients in today’s cancer-fighting drugs come from organisms found only in the rainforest. Vincristine, extracted from the rainforest plant Periwinkle, is one of the world's most powerful anticancer drugs. It has dramatically increased the survival rate for acute childhood leukaemia since its discovery.

      · Nobody knows what effect the disappearance of the rainforest will have on our planet but there is general scientific agreement that it will impact everything from climate to the air we breathe, it is a vital part of our global balance.

      It will, absolutely, 100%, lead to (or speed up) the downfall and eventual death of (almost) all of the human race. Our genetics, and our body are beginning to stray from a natural and sustainable architecture... we're evolving outside the scope of our natural world. Most notably... single celled organisms that we've co-evolved with for millions of years are now falling out of step with our chemistry and us to theirs... this should eventually lead to a future human being with a very weak immunity disposition (like more allergies. The spread of allergies basically came eventually with the widespread use of soap and the elimination of a species or two of symbiotic parasites in our body!), coupled with much more toxic air and more atmospheric particulates. I think we're in big trouble, personally.

      I originally learned about it from an awesome free radio show called RadioLab:

      http://www.wnyc.org/shows/radiolab/

      You can download all the shows there, or at least you could last time I was there. don't see the links now. It was from an episode called "Parasites".

      I also highly recommend the book "Survival Of The Sickest". It was short and really informative. To the point.

      That radiolab broadcast got me very interested in the potential symbiotic relationships we have with the other lifeforms on the planet. The book drove the point home: Understanding and working WITH, not against, single celled organisms is really our only hope of survival from long term degradation of our immune system, among other things. They evolve much faster than we do... so we need to learn to harness them... for what they are, in essence, are little gears that fit with certain chemicals and turn them into others. Nature's nano machines with the capability to "learn" and store information (in the form of DNA). Our technology pales in comparison to millions of years of stored evolutionary data.

      Also of interest... Quorum Sensing ... this is the "language" that bacteria use to "talk".
