Windsor students were schooled this morning by one of Canada's leading environmental activists.

David Suzuki met with as many as 8,000 students at the WFCU Centre to deliver a message of preservation during Earth Week.

"It’s their future that’s at stake now," Suzuki told Early Shift host Tony Doucette. "I have grandchildren, and the world they inherit is a radically different one from the one I grew up in.

"We partied as if there is no tomorrow. We never thought about the consequences. The consequences are that our kids and their kids will feel more and more heavily our impact."

Suzuki said technology and social media has made spreading environmental information easy.

"They’re very aware of a lot of this stuff. They’re much more plugged in to what’s going on in the world around them," Suzuki said.

Suzuki spoke to students about protecting the environment, climate change and the policies around these issues.

"We’ve never been at the top of the food chain until very recently. We’ve suddenly become this powerful force. We’ve become very adept at exploiting a huge amount of the planet’s resources," Suzuki said.

He said everything humans consume comes out of the earth, and for the most part, is put back into it. He said the impact is minimal when there are fewer people, but there are 7 billion people on the planet.

Suzuki ran his first program about global warming and climate change in 1988 and thought at the time that "we had 60 or 70 years to fix the problem."

"Now we know it’s very, very serious," Suzuki said. "The reality is, climate is changing.

"If we can pull back our effect, nature is capable of tremendous regeneration."
