From the Earth Day website: Over the next five years, as Earth Day moves closer to its 50th anniversary, we’re calling on you to help us achieve one of our most ambitious goals yet —we’re planting 7.8 billion trees and we’re starting now. Trees help us breathe clean air. Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.
This is just one of many reasons why we should focus on trees. Let’s get planting!
