One of the Southeast’s largest eco-benefits, the Captain Planet Foundation’s annual Benefit Gala will be held on Friday, Dec.8 at the InterContinental Buckhead Atlanta (3315 Peachtree Road NE) from 6:00-9:30 p.m. “Avengers” actor Mark Ruffalo will receive the Superhero for Earth award. Single tickets are $750, $1,500 per couple, and corporate tables start at $5,000. The charitable evening will raise funds for the Foundation’s programs, which promote and support hands-on environmental education projects in K-12 schools in all 50 states and 25 other countries. Funds will also support Project Learning Garden, which is over halfway to its goal of having a learning garden in 525 City of Atlanta, Cobb, DeKalb, Fulton and Gwinnett public elementary schools by 2020.
