Different from Earth Day which falls on April 22 every year, Earth Hour has been known for its "lights off" moment. On the last Saturday of March every year, from 8:30 p.m. to 9:30 p.m., millions turn off their lights to show they care about the earth. Last year's Earth Hour, with the theme "Create the Biggest Hour for Earth", was even more important as it shared the same day as World Water Day. However, it's not enough to have such an hour every year. What matters is how we can be kinder to the earth every day.
Planet-friendly food
You might not realize it,but the meat industry has a huge influence on forests around the world. Large numbers of trees are cut down to make space for soy(大豆)and other plants that are used to feed animals. Have a chat with your parents about going meat-free for a day every week. Also, foods like vegetables, fruit and nuts are helping the planet.
Go green and save money too
Electricity produced by burning fuels like oil, coal and gas causes global warming and pollution. Ask your parents how they heat your home and suggest using green energy like wind or solar power. Another tip is to remember to turn off the electricity whenever you leave a room. Cutting down on screen time is actually good for both your health and the earth.
Waste less, help more
Waste is a big problem! We've talked about saving electricity. What about food waste? Every year, 1.3 billion kilograms of food is wasted around the world. That's one-third of the total amount, which can feed up to 1.26 billion people. Try to talk to your parents about buying a proper amount of food. More importantly, find some ways online for leftover food at home.
