If you haven’t encountered a TED Talk yet, you’re missing out on a great source of innovative thinking and new ideas. TED stands for Technology Entertainment and Design and they are a series of video talks held by a diverse range of people from all over the world, about every topic imaginable.
Created by a non-profit organisation, TED is devoted to ‘Ideas Worth Spreading’, and since the arrival of video streaming on the Internet, it has grown into a huge site, with a gigantic database of video talks, all of which are free to watch.
Many TED Talks are concerned with the environment and what we can do to make a positive impact on it, and this article looks at twenty of the best environmental TED Talks, presented by some of the world’s most innovative thinkers.
