Define Ocean Acidification, Celebrities: Hollywood On Global Warming

Ocean acidification, which has been also referred to as “global warming’s evil twin” and other similar titles, has been the subject matter of some recent films and documentaries that have emerged from Hollywood.

Many Hollywood celebrities have linked ocean acidification — which is caused when excess levels of carbon dioxide (CO2) are released into the atmosphere and dissolve into the ocean — along with global warming in their activism.

Here are three celebrities who have unabashedly voiced their concerns for the oceans’ future:

1. Harrison Ford

Ford, 72, of “Star Wars” and “Indiana Jones” fame, has been a board member of Conservation International for many years. After filming the documentary, “Years of Living Dangerously,” about environmental and climate issues, Ford said, “Is it too late to teach our kids the difference between right and wrong? If we are not ready to redress something happening on our watch, how can we expect our kids to do something about it?” reports The New York Times. He added, “Nature will be just fine without us. Nature doesn’t need people. People need nature. That is why we can’t save ourselves without saving nature.”

2. Leonardo DiCaprio

DiCaprio, 40, of “Titanic” fame, delivered a speech at the United Nations in 2014 rebuking public reluctance to challenge global warming and related issues. According to The Guardian he said, “Every week, we’re seeing new and undeniable climate events, evidence that accelerated climate change is here now. We know that droughts are intensifying, our oceans are warming and acidifying, with methane plumes rising up from beneath the ocean floor ... We only get one planet. Humankind must become accountable on a massive scale for the wanton destruction of our collective home.”

3. Sigourney Weaver

Weaver, 65, of “Alien” fame, co-starred in “Avatar,” an environmentally-charged film that takes place on the fictitious planet, Pandora. She later wrote in The Huffington Post blog, “Back on planet Earth, we have our own life force — the oceans. Our oceans — which generate most of our oxygen, regulate our climate, and provide most of our population with sustenance — are essential to all life on earth. Yet, our oceans face a threat as dangerous as any Pandora faced: ocean acidification ... Without healthy populations of ocean fish, or vibrant reefs, many coastal communities could lose their primary food source or their most promising job opportunity. We cannot prosper unless the ocean prospers, too.”
