We have a lot of holidays that are strictly celebrated by the United States. Like President’s Day, Labor Day, Memorial Day, Martin Luther King Day. I mean sure, you can celebrate them with us if you live outside of the states - no one’s stopping you - but the significance of the day can only really be felt by Americans. Not Earth Day. No, Earth Day is a holiday that needs to be observed by everyone occupying God’s green earth. It’s a day we need to all come together and keep our Earth Globablly Green. Buy this T-Shirt for Earth Day. For our planet.
