Earth Day Texas, the world's largest green event of its kind, returned this weekend to Fair Park in Dallas for a few days of food, fun and free events for the whole family.

Tiny houses, fun music and more: 5 reasons to go to Earth Day Texas

With the focus on innovation and education, there was plenty to do at this weekend's festival. Tiny House Village showed off the newest trend in affordable and environmentally-friendly housing, LEGO Build For Change tasked kids with building something cool over three days, and there was plenty of awesome food and films. Oh, and some music too, from the likes of Kinky Friedman, Telegraph Canyon and more. 

The festival, whose plan this year was to be seen as even more international than before, brought recycling robots, solar technology and hydrogen power to Fair Park. It was fun, free and runs through tonight, April 24.

Check out some photos of the festivities below.
