Lululemon’s founder is the latest to put their money where their mouth is and help save the planet … by pledging a HUGE chunk of change to help preserve the wilderness.

Chip Wilson, founder of Lululemon Athletica Inc., and his wife Summer are pledging $100 million Canadian — about $75.8 mil U.S. — which marks the biggest gift the billionaire philanthropist’s ever given.

The cash will be used by the Parks Foundation in British Columbia to acquire wilderness space in the area … with the goal of turning massive amounts of land into spots locals can then use for money-making purposes such as tourism.

In a recent interview, Chip — who’s worth $5.6 billion — says, “Our vision for our family is providing components for people to live a longer, healthier, and more fun life.” Chip and Summer are hoping to get matching donations from other philanthropists, governments and local businesses.

Shout out to the Red Hot Chili Peppers … because give it away, give it away, give it away now is the theme of the week among apparel-peddling billionaires.

The founder of Patagonia, Yvon Chouinard, did his part this week to help fight the climate crisis … giving away his $3 billion company to an environmental nonprofit company called the Holdfast Collective.

While Patagonia will remain a for-profit company, after every year, all cash they make will be handed over to the Holdfast Collective to help end the climate crisis.
