The event was first launched in 2008 by Town Square as the first Earth Day festival in north Brooklyn, and this year featured 92 exhibitors and organizations.
The event also featured a variety of activities for residents to enjoy, including local food, arts and crafts, games, live music performances, and fitness classes while also learning about sustainability and how to get involved.
"It brings the community together to learn about what's sustainable, but also to reconnect with our neighbors and our friends in a fun grassroots manner," said Susan Anderson, executive director of Town Square.
A highlight at the festival was the Greencycle Swap, where residents could drop off and take clothes, books, toys, electronics and more. The remaining items are donated to Home Life Services shelters throughout Brooklyn and the Bronx.
"I personally think we really use too much, we waste too much," said Robert Ming, co-founder and creative director of Smart Toddler.
Ming, who hosted a table where children and families could learn to make airplanes out of recyclable materials, said the event helped children to learn about green ideas and how to improve the future of the environment.
"If you can reuse stuff like this especially with kids, you're teaching them at a really young age the fun benefits of recycling," he said. "It shows them we can do something with this other than throw it away."
Anderson explained the festival is especially beneficial for organizations that work towards improving the environment.
"To have an event like this where they can come out and share what they are doing with a broad audience and also reconnect with each other is rare, and so I think that's what this event offers," she said.
