ENERGY SUPPLY AND USE
Causes
Societies have become increasingly dependent on nonrenewable sources of energy [fossil fuels].
Long term use of nonrenewable energy will change the climate [unsustainable].
Effects
Climate change is here.
The climate change affects the weather, the biosphere [ecosystem shifts, flora and fauna],
and the hydrosphere [shifts from polar ice caps and glaciers to surface water and groundwater].
Solution
Conserve nonrenewable energy.
Research and develop new types and sources of renewable energy.
Shift to renewable energy.
