Top 10 List of the Main Causes of Global Warming (but no quantitative data%, so there is still lack of valid detailed info) 10. Greenhouse Effect (mainly its carbon dioxide) 9. Air Pollution 8. Depletion of Ozone Layer 7. Volcanic Eruptions (its sulphur dioxide) 6. Melting of the glaciers 5. Deforestation 4. Industrial Advancement 3. Use of Chemical Fertilizers (its nitrogen oxide destroy ozone layer even more faster than any other greenhouse gases) 2. Burning of Fossil Fuels (releases extra carbon dioxide in a very large amount) 1. Human Activities

Four hundred million hectares--an area bigger than Mexico and Indonesia combined. About the size of the Brazilian Amazon. That's how much of the world's tropical forests are being selectively logged. Unfortunately, these logged forests are intensely vulnerable to being cleared for oil palm, slash-and-burn farming, and other land-uses. With the rapid decline of old-growth tropical forests, retaining logged forests--and devising economically viable ways to manage them over the long term--are key priorities for the future.

No nation on Earth is losing forest faster than Indonesia. ALERT assessed the specific drivers of forest loss in Indonesia, For one thing, the biggest driver of forest loss wasn't oil palm, but rather industrial pulpwood plantations. Mega-corporations such as Asia Pulp & Paper and APRIL have cleared vast expanses of rainforest and peat-swamp forest for such plantations, especially in Sumatra and Indonesian Borneo. Second on the list was industrial logging. This indicates that logged forests in Indonesia, which still harbor a great deal of biodiversity (see this blog), are intensely vulnerable to being cleared. Oil palm, while still important, was actually number three on the list of industrial forest destroyers. Notably, the authors surmised that over half of all deforestation was caused by actors other than the big three above--including slash-and-burn farming, legal and illegal mining, and other causes.
