Profits from deforestation range from near zero to thousand of dollars a hectare.In some places, there are huge incentives to convert or degrade forest.In Cameroon, oil palm and intensive cocoa cultivation has a net present value of more than $1,400 a hectare.In Brazil's cerrado, some conversions result in land values over $3,000 a hectare.And India offers very high values for land devoted to coffee cultivation in the Western Ghats, a biodiversity hotspot.

One in ten known species on Earth lives in the Amazon. Its forests contain 90-140 billion metric tons of carbon, the release of even a portion of which would accelerate global warming significantly. 30 million people living in the Amazon depend on its resources and services – not to mention many millions more living as far away as North America and Europe, but still within the Amazon’s far-reaching climatic influence.

environmental importance of the world’s vast tropical rainforests is well known – both

Rainforest in Honduras WHY ARE RAINFORESTS IMPORTANT? Flying over the heart of the Amazon is like flying over an ocean of green: an expanse of trees broken only by rivers. Even more amazing than their size is the role the Amazon and other rainforests around the world play in our everyday lives. While rainforests may seem like a distant concern, these ecosystems are critically important for our well-being.

Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet. Rainforests: help stabilize the world’s climate; provide a home to many plants and animals; maintain the water cycle protect against flood, drought, and erosion; are a source for medicines and foods; support tribal people; and are an interesting place to visit

They provide a habitat for plants and animals Tropical rainforests took between 60 and 100 million years to evolve and are believed to be the oldest and most complex land-based ecosystem on earth, containing over 30 million species of plants and animals. That's half of the Earth's wildlife and at least two-thirds of its plant species!

contain 1000 trees with up to 300 species.

There are many more thousands of rainforest plants and animals species still waiting to be discovered.

Forests cover 31% of total land area.   The livelihoods of 1.6 billion people depend on forests.   Forests provide a home to more than 300 million people worldwide.   The total global trade in forest products was valued at around $379 billion in 2005.   Forests are home to 80% of terrestrial biodiversity.

In this high-tech world of metal and plastic, it's easy to forget that many things are still made with good, old-fashioned wood. Countries with lots of forest stand to benefit from the lucrative timber trade, but at what cost to their ecological footprint? Here are five major timber exporters, and who is buying their wood. © WWF / GOOD / SectionDesign The Global Timber Trade, Who's Buying, Who's Selling?

The five most forest-rich countries are the Russian Federation, Brazil, Canada, the USA and China, and they account for more than half of the total forest area. Ten countries or areas have no forest at all and an additional 54 have forest on less than 10% of their total land area.

Five Basic Steps to Saving Rainforests "TREES" is a concept originally devised for an elementary school audience but serves well as set of principles for saving rainforests and, on a broader scale, ecosystems around the world. Teach others about the importance of the environment and how they can help save rainforests. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment. Establish parks to protect rainforests and wildlife. Support companies that operate in ways that minimize damage to the environment.
