18. Earth Day (April 22nd)
Earth Day is a celebration of the only home we have in the universe and its preservation and care for it. On this day, there are many activities held worldwide—primarily things related to environmental science, which are used to educate everyone of all ages. The event was proposed in 1969 at a UNESCO conference in San Francisco by activist John McConnell to honor Earth. What started as a small-town event ended up being a Nationwide event that began in 1970. More than 20 million people participated the first year, which remains the largest single-day protest in human history.
Today, 141 nations celebrate this event after it went global in 1990. On 2020 Earth Day, over 100 million people from many parts of the planet marked the 50th anniversary, making it the most significant online mass mobilization in history. On record, over 1 billion people have joined the movement to date to help lower global warming and the environment in general. What’s great about this anniversary is that there are many activities for everyone that are easy to do and won’t cost anything. Turn off your lights, conserve water, and plant a tree. Even if it sounds like tiny things, it can help make this planet a better palace.
