What is Earth Day?

Earth Day is held every year on 22 April to celebrate our planet and raise awareness about protecting the environment.

Its organisers say that over 1 billion people in more than 190 countries are involved.

It began back in 1970, to highlight pollution and environmental issues.

Earth Day helps remind everyone to look after our planet. It encourages people to help stop pollution, protect animals and nature, and do things that help slow down climate change.

Around the time of Earth Day, people often plant trees, clean up litter, recycle, and join campaigns to protect nature. They might also start to make small environmental changes to their lifestyle so that they can enjoy our Earth for many more years to come.

  • Reducing the amount of energy they use by switching off lights and appliances when they are not being used.

  • Reusing shopping bags, plastic bottles, and containers rather than throwing them away.

  • Recycling rubbish so that it can be turned into new things.

  • Upcycling old things like clothes or furniture – keeping them in use for longer.

  • Eating sustainably by choosing locally sourced, seasonal fruit and vegetables.

  • Cleaning up the environment by always putting litter in a bin.

  • Walking, cycle, or using public transport if and when they can.

  • Planting native trees and flowers. Trees absorb carbon dioxide and give us oxygen. Pollinator-friendly flowers provide food for bees and butterflies who then spread pollen, which helps plants to reproduce and create seeds and fruits for us to eat.

  • Talking to friends, family and leaders about protecting nature.

Around the world, it is difficult to know the exact number, but it is estimated that people plant roughly 1.8 to 1.9 billion trees every year. This sounds like a huge number - but far more trees are cut down each year.
