Document Summary
Desert cities, destruction of soil and underground habitat by off-road vehicles, depletion of groundwater, land disturbance and pollution from mineral extraction. Off road vehicles, clear cutting, pollution of forest streams. Air pollution blowing in from urban areas, agriculture, timber and mineral extraction. Human activities are likely to affect biome placement in the future. Plants and animals respond ecosystems become threatened. Certain ecosystems are more vulnerable to climate change than others northeast is very sensitive. Based on long term differences in average temperature and precipitation. Largely determines the types and locations of the earth"s deserts, grasslands, and forests. The earth"s terrestrial systems provide important ecological and economic services. Human activities are degrading and disrupting many of the ecological and economic services provided by the earth"s terrestrial ecosystems. Tying it all together: a temperate deciduous forest and sustainability. Climate plays a key role in determining the nature of terrestrial ecosystems. The earth"s climate system helps distribute heat from solar energy.
