Sanibel Sea School will begin its winter season of educational opportunities for adults on Friday, January 18th with a screening of the award-winning film DamNation. The screening will be held at 5 p.m. at Sanibel Sea School’s Flagship Campus, 455 Periwinkle Way.

DamNation evaluates whether dams are a positive form of development, and if better alternatives exist. “You might be surprised by the impacts dams can have on things like communities, fish populations, and water quality,” said educator Shannon Stainken.

The second session will be a field trip led by the organization’s executive director, marine biologist Dr. Bruce Neill, to learn about harmful algal blooms (HABs). The trip will be from 9 a.m. to noon Jan. 25. Participants will learn about the organisms that cause red tide and other HABs in our area, how these blooms impact our ecosystem, and what we can do as individuals to help solve the problem.

The cost for each event is $10. To RSVP, call (239) 472-8585. To learn about additional sessions, visit www.sanibelseaschool.org/sanibel-adult-programs. Sanibel Sea School is a 501(c)(3) nonprofit whose mission is to improve the ocean’s future, one person at a time.
