Earth science is the study of earth, air, and water. Meteorologists, oceanologists, and geologists are all examples of earth scientists. These scientists are very important. They help us understand things like climate change and shifting ocean currents — problems that are having a major impact on our planet. 

With climate change worsening, the world is going to need more earth scientists. One way to get involved is to celebrate Earth Science Week October 10-16. This year’s theme — “Water Today and for the Future” — is all about learning to understand, conserve, and protect water.

Why Do We Need to Protect Water?

Water is the most abundant substance on our planet. All living things depend on it to live and thrive. The world’s largest ecosystem, the ocean, contains about a million species. The earth is also teaming with rivers, lakes, and streams. The world’s largest river, the Amazon, which winds over 4,300 miles through South America, contains thousands of plant and animal species. The Caspian Sea in Central Asia is the world’s largest lake (despite its name), and contains hundreds of animal and plant species. Even small waterways are vital to maintaining healthy ecosystems. Since waterways are usually connected, pollution that ends up in one often affects others. 

From plastic waste to warming temperatures and shifting ocean currents, the world’s waterways are increasingly under threat. But there is plenty we can do to solve these problems.
