How might climate change impact forest cover?

• Warmer temperatures mean trees will grow better, increasing forest cover.

• Changes to temperature and precipitation will cause all forests to shrink.

• Forests may migrate as geographic range for forest species change.

• More carbon dioxide in the atmosphere will help trees grow, as they breath in CO2 and breath out oxygen.

How do government subsidies for agriculture increase deforestation?

• This costs money which could otherwise be spend on forest protection initiatives.

• The subsidies make agriculture more economically beneficial relative to industries that use the ecosystem services of intact forests.

• Agricultural subsidies ensure food security, leading to population increases that in turn place more pressure on forest ecosystems.

• Wars and civil disruption displace populations which may place pressure on forest biomes.

• The desire for economic growth demands industrial expansion to alleviate poverty in developing nations, often at the cost of forests.

• Infrastructure improvement factors such as mines, dams and transport systems.
