Today is Arbor Day. That means in just three years, America's oldest environmental celebration will turn 150, and the Arbor Day Foundation is already planning a redwood-sized birthday present. The foundation, the largest non-profit dedicated to planting trees, has announced a new goal: planting 100 million trees by 2022.
"It can be easy to take trees for granted, but they are absolutely critical to maintaining balance on our planet—supporting clean air and water, healthy food and a livable climate," Arbor Day Foundation President Dan Lambe said in a press release. "With an estimated 18 million acres of forests lost globally each year, that balance is being shaken."
The benefits of trees are incalculable, from providing oxygen and cooling our streets with shade, to helping us relax and connect with nature.
But in a world experiencing increasingly extreme weather, many tree species are at risk. For instance, last year's devastating hurricanes—Harvey, Irma and Maria—snapped and downed innumerable trees, altering treasured landscapes in Texas, Florida and the Caribbean.
