National Geographic have just released a documentary called "Before the Flood", in which Leonardo DiCaprio explores the world in regards to the effect of climate change, and what we can do to prevent even more harm to our planet.

Before the Flood, directed by Fisher Stevens, captures a three-year personal journey alongside Academy Award-winning actor and U.N. Messenger of Peace Leonardo DiCaprio as he interviews individuals from every facet of society in both developing and developed nations who provide unique, impassioned and pragmatic views on what must be done today and in the future to prevent catastrophic disruption of life on our planet.

It’s an incredible film, and while I was aware of most of climate change, it still opened my eyes up to a lot more harm we are doing. There’s also some people that are actively trying to turn it around, but they alone won’t be able to fix the planet, everyone needs to make themselves aware. Then the process of fixing things, won’t be as difficult.

You can watch the video on YouTube, or below if the embed works on your device. And after that, you can watch more videos on the National Geographic YouTube channel, and everything else they do on their website.

Also, Leo’s speech at the end! Wow.

I watch TED videos a lot, but I thought this one definitely had to be shared.

Forests don’t have to be far-flung nature reserves, isolated from human life. Instead, we can grow them right where we are — even in cities. Eco-entrepreneur and TED Fellow Shubhendu Sharma grows ultra-dense, biodiverse mini-forests of native species in urban areas by engineering soil, microbes and biomass to kickstart natural growth processes. Follow along as he describes how to grow a 100-year-old forest in just 10 years, and learn how you can get in on this tiny jungle party.

It’s just under 10 minutes, but I found it very fascinating, and it proves there are things we can do to kickstart nature.
