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.

Also, foods like vegetables, fruit and nuts are helping the planet.
