In 2018 the United Nations' Intergovernmental Panel on Climate Change (IPCC) report, the U.N. suggests an additional 2.5 billion acres (1 billion hectares) of forest in the world could limit global warming to 2.7 degrees Fahrenheit (1.5 degrees Celsius) by 2050. That's a lot of trees, but you could plant one or two, right? One young tree can absorb CO2 at a rate of 13 pounds (5 kilograms) per tree. Every. Single. Year. And that's just an itty bitty baby tree. Once that tree reaches about 10 years old, it's at its most productive stage of carbon storage. Then it can absorb 48 pounds (21 kilograms) of CO2 per year. Trees also remove all other kinds of junk from the air, including sulfur dioxide, nitrogen oxides and small particles. So go ahead, plant a tree. It's good for everybody.
