            Did you know health is not just about not being sick? It is about feeling well. In healthy ecosystems, you can find plants, animals, water, rocks, and soil, all interacting with many microbes. Thanks to this biodiversity we have clean air, fresh water, and nutritious food. Bees and other animals pollinate flowers to help grow fruits and vegetables. Birds spread seeds that grow into trees and forests. Plants clean the air we breathe. And people feel better in nature. Healthy ecosystems, therefore, keep people healthy. While public health programs teach people about healthy food and give them access to medicines, people make ecosystems healthier by protecting nature. You can help too, by taking care of your health and your surrounding ecosystem, learning about the world, and supporting decisions and actions that protect nature and people. By becoming guardians of Earth’s biodiversity, we can all have a healthy future together.more » « less
