Proforestation
The great forests that have long existed on the Earth draw in huge amounts of carbon from the atmosphere. Proforestation is protecting the forests there still are, encouraging them to continue to heal and grow.
Geothermal
Geothermal energy is a sustainable and renewable power source. It is thermal energy generated and stored in the Earth. Geothermal power plants use the steam or hot water to drive turbines, which in turn generate electricity.
