Speaking at an event for the environmental group Conservation International on Thursday, Harrison Ford blasted the Trump administration's handling of climate science.
"We face an unprecedented moment in this country. Today's greatest threat is not climate change, not pollution, not flood or fire," said Ford, according to the Hollywood Reporter.
"It's that we've got people in charge of important shit who don't believe in science."
Ford has been involved with the non-profit for nearly 26 years, and he currently serves as the executive vice-chair. On Thursday, during the organization's 30 year anniversary, Ford was honored with the Founders' award for his dedication and service.
Not one to miss an opportunity, Ford used his acceptance speech to criticize those politicians who allow "political or economic self-interest denigrate or belittle sound scientific understanding of the causes and effects of human pressure on the environment."
"I'm here tonight for one reason: I care deeply for the natural world. It's not about me, it's not about me at all, it's about this other world we're going to leave behind," Ford said.
"If we don't stop the destruction of nature, nothing else will matter. Jobs won't matter, our economies won't matter, our freedoms and ethics won't matter, our children's education and potential won't matter, peace, prosperity. If we end the ability of a healthy natural world to sustain humanity nothing else will matter, simply said."
Ford was first introduced to Conservation International in 1999. The leading environmental group, which provides a fund for scientists in 30 countries to identify and overcome biodiversity threats, impressed him so much that he joined the organization's board. After years of dedication and hard work, Ford now sits on the board's executive committee.
"Other than my family, doing this work has been the most important thing of my life," he said.
"Nature doesn't need people, people need nature."
