There is no planet b. there's no dome on the moon. matt damon is not out there figuring out how to grow us all some potatoes if we ruin this planet (well, i don't know that for sure). and an inability to understand science is not a valid argument against it. so, what better way to celebrate earth day than with a donation to your favorite environmental organization? or planting a tree? or picking up trash in your neighborhood? or giving up single-use plastic? we can do better ya’ll...it starts small.
