We're changing the planet faster than any other species in Earth's history. What does this mean for our future?
Our species has only been around for about 300,000 years, but we have transformed ecosystems wherever we've gone -- first slowly and locally, now faster and on a global scale because of our technology and vast population.
The fossil record reveals what happened during earlier periods of dramatic change. By exploring Earth's past, we can understand the changes happening now and learn how our choices shape our future. |
