Earth Day is observed annually on 22nd April since 1970 as a day of action to change human behavior and create global, national and local policy changes to cease negative implications casted over the planet Earth.
The theme for Earth Day 2021 is “Restore Our Earth”, which focuses on natural processes, emerging green technologies, and innovative thinking that can restore the world’s ecosystems. In this way, the theme rejects the notion that mitigation or adaptation are the only ways to address climate change. It is up to each and every one of us to Restore Our Earth not just because we care about the natural world, but because we live on it. We all need a healthy Earth to support our jobs, livelihoods, health & survival, and happiness. A healthy planet is not an option — it is a necessity.
Earth Day is widely recognized as the largest secular observance in the world, marked by more than a billion people in 192 countries every year. Now, the fight for a clean environment continues with increasing urgency, as the ravages of climate change become more and more apparent every day.
