I added a link to cool websites where you can watch documentaries (in episode format) about nature and the environment.
The Nature of Things is awesome, informative, fun to watch…and narrated by David Suzuki-so obviously super cool
Nature-I love these episodes, I learn so much and they have so many cool and interesting facts. PBS is only available in the US, but you may be able to find the episodes somewhere else. Check them out if you get a chance.
