Planting trees is good, but eliminating deforestation is better.
Every year, an estimated 15 billion trees are chopped down across the planet to make room for agricultural and urban lands and other uses. We’ve cut down so many that what’s left is about half of the number of trees that the Earth supported before the rise of human civilization, and scientists warn that it’s not helping our climate.
Planting more trees is one way to offset deforestation. But now, a report from the United Nations Intergovernmental Panel on Climate Change finds that to have a shot at combatting the climate crisis, we’ll need to cut down fewer trees.
Global deforestation is a major source of greenhouse gas emissions. As a Mother Jones reporter explains: "The way we eat, farm, and cut down forests contributes in a major way to the climate problem. Deforestation, agriculture, and other land use are already responsible for 23 percent of the rise in human-caused greenhouse gases, and agriculture is responsible for 44 percent of methane emissions." “We cannot plant trees to get ourselves out of the problem that we’re in,” Pamela McElwee, a professor of human ecology at Rutgers University and an author on the report, said. “The trade-offs that would keep us below 1.5 degrees, we’re not talking about them. We’re not ready to confront them yet.”
