The first trees emerged about 400 million years ago. Humanity needs only about 18,000 years more to destroy them completely. This estimate is overly simplistic and assumes a “no change” scenario from current trends in deforestation—an annual average loss of -0.13 percent—but it forces us to examine the data from a what if perspective, keeping in mind that forests are one of the most important natural filters and producers of oxygen.
The 1992 Rio Earth Summit was viewed as the turning point for global environmental policy, seeking to overturn disruptive ecological and environmental trends compounded by the industrial revolution and to spur development of national-level environmental policies to address emerging issues. The persistence of deforestation for land clearing and the continued popularity of wood in building and manufacturing despite the critical volume of forest coverage required is (disturbingly) evident in the data.
The world's 149 million total square kilometers of land is almost equally distributed among agricultural, forest, and other lands. Agricultural land consumes a slightly disproportionate share at 38 percent of the world's land area. About one third of the agricultural land is used as arable land, two-thirds by permanent meadows and pastures, and the remaining 3 percent as "permanent crops." An examination of the cross-country distribution of agricultural land reveals that China is the world's leader in total agricultural land, whereas Russia--the largest country by total land mass--has half as much agriulcultural land as China. Russia...
Temporary crops is all land used for crops with a less than one-year growing cycle and which must be newly sown or planted for further production after the harvest. Countries with the biggest square of temporary crops are Russia, Australia, Argentina, Ukraine, and Sudan. These countries have more than 50 percent of total temporary crops.
