How to celebrate Earth Day

Earth Day

The first Earth Day was held on April 22, 1970. The holiday has been celebrated on this day every year ever since then.

In 2014, NASA(美国国家航空和宇航局)took an active part in Earth Day. Their Global Selfie event asked people to take a photo of themselves outside, and send it to NASA. They then put these pictures on a map of the world for all to see to commemorate their participation (纪念他们的参与)in this important day.

我们可以做许多小事来保护地球。the following are some easy ideas!

Ride your bike

if you live close enough to your school, ride a bike to and from classes. Not only is it good for your body, it’s also good for the environment! And if you aren’t nearby or don’t have a bike, take public transportation.

Use your own water bottle

Just throwing your plastic water bottles into the recycling bin doesn’t mean they are not hurting the environment. Besides the fact that it takes a lot of oil to make all of those bottles each year, there are still over two million tons of water bottles that have ended up in U.S. Landfills(垃圾填埋场).Buy a reusable bottle, so you’ll be getting fresh water every time.

Get produce from a local farmer’s market

Besides supporting area businesses, you’ll also be helping the earth by buying your fruits and vegetables from local farmer’ s market. That’s because food in the supermarkets travels about l,500 miles to get to you, and all that shipping can cause pollution. When you buy locally, it’s transported in shorter distances(距离).

Some Earth Day themes

Earth Day 2019: Protect Our Species(物种)

Earth Day 2018: End Plastic Pollution

Earth Day 2016: Trees for the Earth
