As Austin continues to grow so does the push to generate more sustainable food. The city has several community gardens that are now so busy that there are waitlists to get into them.

Festival Beach Community Garden opened for business about six years ago. Juilo Perez has been here since the beginning. He says as Austin grows, so does the city's need for sustainable food.

"It seems to be growing quite a bit," Perez said. "A lot more people are wanting to do it."

"It's really important to make sure that we're saving green space for community gardens and farms because if we don't, we won't have a place to grow food locally anymore," Sari Albornoz with the Sustainable Food Center said.

According to the City of Austin website, Austin has 20 community gardens on city land which produce more than 100,000 pounds of fresh, local produce each year. All of them keep a light environmental footprint.
