As we all may know, the environment is something that is greatly in danger, and it is our job to protect it. Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilization and sustain our economies. It's that simple: we could not live without these “ecosystem services”. Student: Neo Peralta Bravo
