Each year, hundreds of TED talks are given at TED and TEDx events around the world and many of them focus on agriculture, food and the enivornment.

TED is an organisation devoted to spreading ideas and stimulating conversations in the form of short, powerful talks covering all topics, from science, to agriculture, to business, to global issues. On top of the events, each TED Talk is recorded and posted on the TED website, where videos attract millions of views.

Here, we've chosen three agriculture TED Talks that you might find interesting.
