Growing global demand for land for the production
of agricultural commodities has resulted in sometimes
irreversible changes to the world’s forest cover. The Amazon is now part of a

Decreases and increases in forest area, 1940-2005. Costa rica has recently recorded a change from having
a net loss of forests to having a net gain

Defining what constitutes a forest is not easy. Forest types differ widely, determined by factors including
latitude, temperature, rainfall patterns, soil composition and human activity.
