Livestock and Climate Change explains that the sole way to meet the objectives of recent international climate negotiations may be by replacing at least 25% of today's livestock products with alternatives. That's because the only path by which a significant magnitude of carbon can be absorbed from our atmosphere may be through planting trees -- or allowing them to regenerate –- on a substantial amount of the vast expanses of land now set aside for livestock and feed production. Anyone can get involved, e.g. by taking action described by groups such as Friends of Trees and its national partner Alliance for Community Trees, as well as Trees for Life and The Fruit Tree Planting Foundation. Below is a map showing areas ripe for planting trees and regenerating forest.
