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.

"No-catch" fishing zones help to prevent the global issue of overfishing by allowing for certain areas of bodies of water to be deemed illegal to fish in. By limiting places countries can fish in, we allow for populations of sea life to be restored.
