Climate Crusader Tia Nelson continues legacy of her father and founder of Earth Day

WAUNAUKEE, Wis. (CBS 58) -- It's no coincidence that president Joe Biden chose this week’s celebration of Earth day to host the Leaders’ Summit on Climate. Odds are, the president will mention the name Gaylord Nelson during the virtual gathering of world leaders. In 1972, the late Wisconsin governor, US Senator and Earth Day founder encouraged Biden to carry on when his wife and baby were killed in a car crash a month after he was first elected to serve Delaware in the US Senate.

48-years later, it was Gaylord Nelson's daughter, Tia, showing support for Biden in his bid for president.    

On CBS 58 Sunday Morning, Mike Strehlow caught up with the life-long environmental crusader at a place she calls “Papa's park” to talk about her father's legacy, and her never-ending drive to put the brakes on climate change.
