How much forest is there now?

Of course, these debates occur in a context where total global forest cover has long been in dramatic decline. The total area of forests and woodlands around the world is estimated to have declined from 6,215 million hectares in the year 1700 to 5,053 million hectares by 1980, a loss of almost a fifth of the world's forest over a relatively short period (Grainger 2008). Where did all of these trees go?

Most available evidence points to deforestation being closely associated with the expansion of human industry, urbanization, and agricultural expansion. Forest is cleared to produce food and cash crops and to make way for urban development. Many secondary effects of human activity also hamper forests, including climate change and atmospheric pollution effects, like acid rain, which has damaged and destroyed forests throughout North America and Europe.

Acid Rain Deposition of rain or snowfall with unusually high acidity, resulting from the emission of sulfur dioxide and nitrogen oxides into the air, typically from industrial emissions. This form of precipitation is harmful for plant life and aquatic ecosystems
