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.
Famine
A famine is an extreme and widespread scarcity of food that leads to a significant number of people suffering from hunger and malnutrition. Famine is often caused by a combination of factors, including severe weather conditions, crop failures, conflict, economic instability, and inadequate distribution of food resources.
