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.
Tidal
Tidal power is a form of renewable energy that harnesses the kinetic energy of ocean tides to generate electricity. It takes advantage of the natural rise and fall of ocean tides caused by the gravitational pull of the moon and the sun on Earth's water bodies.
