Every year on 22nd April, over 192 countries celebrate (庆祝) Earth Day. It's an important day. It tells people to help our Earth.
On Earth Day, many people in the US keep their cars at home and go to work by underground. Many children like wearing a blue and green T-shirt on that day. Blue and green clothing is like the blue sky and the green trees.
The theme (主题) for Earth Day in 2024 will be the "Planet (星球) vs. Plastics". Many turtles, seabirds and dolphins get caught in plastic bags. They can't move and some of them even die! That's why people stop using plastic bags and bring their own shopping bags. Some people like drawing pictures on their own shopping bags. They want to tell more people to help our Earth. It is a good way, isn't it? Next Earth Day, will you join them together?
