The Army of Autonomous Robots Restoring Nature | Tom Chi | TED (Level 1)

Most people love nature. However, our world often destroys nature to make money. This happens because we think we must choose between a strong economy and a healthy planet. This idea is wrong. In reality, everything we buy or use comes from the earth. Every product is either mined from the ground or grown in the soil. We can use new technology to fix this problem. First, instead of digging for new metal, we can recycle old car batteries to make new ones. Second, farmers can use computers to understand the soil better. This helps them grow food with less water and fewer chemicals. Finally, we can use robots to fix damaged land. Drones can plant thousands of trees in a few minutes, and underwater robots can plant sea grass. By using these tools, we can help the planet and the economy at the same time.
