Presenters & speakers

Laura Turner Seydel, Captain Planet Foundation


I inherited my passion for taking care of the planet from my dad, Ted Turner, the original Captain Planet. As children, my father instilled environmental stewardship into me and my siblings every chance he got. Growing up, when we took a family beach vacation we had to commit at least one day to picking up litter along the beach. In the winter we put on more layers, before just dialing up the thermostat. Despite his success, my dad drove the same old car he always had. Waste not, want not.

In 1990, my dad created the Captain Planet animated TV series with Barbara Pyle. Captain Planet is still in syndication around the world, and continues to inspire a new generation of Planeteers. Today, I have the honor of acting as Chairperson of the Captain Planet Foundation which supports high-quality, hands-on environmental stewardship projects that have enabled more than 1.1M youth across the U.S. and around the world to make significant environmental improvements to their schools or communities.

I have dedicated my life to continuing my father’s legacy of environmentalism and humanitarianism. Captain Planet taught us that the Power is Ours, and I endeavor through education and outreach to leave this planet a place our children and grandchildren will want to inherit

“When I was ten years old, my family and I got in our car and drove away from our military base in the hot, dry Mojave Desert to start a new life in Warner Robins Georgia. I will never forget waking up in the car after four long days of travel and being blown away by the view outside of my window of Georgia’s thick, green forests blanketing the landscape as far as the eye could see. Before that moment, I had only seen so many trees in textbooks. It was this experience that ignited a fire in me to love, explore and protect the environment.”
