Hakoah Arango, Colombia, Hakko Ranga discussed on Morning Edition
This week in a way, we've been bringing you stories from the future describing a world in which we have actually stopped climate change. And today, we turn to food in a zero carbon world your dinner plate may not look all that different. But some big changes have to happen down on the farm NPR's. Dan, Charles traveled to South America to see how those changes might happen. A scientist named Hakoah Arango was traveling in a forested part of his country Colombia when he ran into a big cause of global warming. He couldn't see it. But he could hear it. You could hear the chainsaw cutting the forest on the local telling us that this is nothing unusual for them. They were hearing every day, and they all knew what would happen next after land. Clearing comes cattle grazing version of cattle grazing, that's careless and destructive and Tim searching her from the world Resources Institute says it's incredibly common grazing land is about two thirds of all the world's agriculture. Land and about a third of that came right out of clearing forest. This is a climate disaster. I because cutting trees and tearing up soil releases huge amounts of carbon dioxide and then cattle release methane a powerful greenhouse gas as they digest grass and leaves. There are greenhouse emissions from other kinds of farming to from plowing and from fertilizer added all up and growing food accounts for a quarter of the entire climate change problem, it could grow to because billions of people around the world are getting richer. They wanna eat beef to there is no solution to climate change that doesn't dramatically reduced the land use demands and greenhouse gas emissions agriculture searching her and his colleagues have laid out a road map for how to do this. It includes lots of things less food wasted ways to capture those fertilizer emissions. But maybe the biggest piece of the solution. Hakko Ranga wants to show it to. Arango works at the international center for tropical agriculture in Colombia. And he's brought me to a farm in the patio valley, not far from the country's Pacific coast. This is cattle grazing land wide grassy pastures lined.
