profoundly change the natural cycle of rivers
air pollution
destroy ecosystems
increases the greenhouse
effect
acid rain
affects both animal and plant life
nuclear accidents by nuclear waste
Final energy use
Extraction of natural resources
Depletion of resources
Waste treatment
Thermal power plants
Use coal with a low sulphur content, to reduce acid ram
Ma intain and increase the size of large forested areas, since they absorb carbon dioxide.
Install special filters on the pipes at the power plant to capture some of the gas pollutants
Nuclear power plants
The use of ocean trenches has its own problems, because there's the risk of the drums surroding and the radioactive material leaking out of them
