A Quote by Ted Danson
Centuries-old habitats such as coral gardens are destroyed in an instant by bottom trawls, pulverized by weighted nets into barren plains. And global carbon dioxide emissions from human activity affect the ocean, changing the pH balance of the waters in a phenomenon known as ocean acidification.

Coral reefs, the rain forest of the ocean, are home for one-third of the species of the sea. Coral reefs are under stress for several reasons, including warming of the ocean, but especially because of ocean acidification, a direct effect of added carbon dioxide. Ocean life dependent on carbonate shells and skeletons is threatened by dissolution as the ocean becomes more acid.
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences.
The industrial way we fish for seafood is harming the marine habitats that all ocean life depends upon. Indiscriminate commercial fishing practices that include miles of driftnets, long lines with thousands of lethal hooks and bottom trawls are ruining ocean ecosystems by killing non-seafood species, including sea turtles and marine mammals.
Coral reefs are the backbone for the entire ocean. They are the nursery for the ocean. About a quarter of all marine life in the ocean spends part of its lifecycle on a coral reef. And there are about a billion or so people that depend on coral reefs for fish for their food, for protein.
As an explorer, I know firsthand there are many places in the ocean so full of life that they should be protected. Coral reefs and mangrove coastlines are stressed already by climate change and ocean acidification, and poor planning will just make their plight worse.
Carbon dioxide pollution is transforming the chemistry of the ocean, rapidly making the water more acidic. In decades, rising ocean acidity may challenge life on a scale that has not occurred for tens of millions of years. So we confront an urgent choice: to move beyond fossil fuels or to risk turning the ocean into a sea of weeds.
Here's the problem - carbon dioxide doesn't contribute to smog and isn't a health threat. All of this is being done because some people believe carbon dioxide is causing global warming, and that preventing carbon dioxide from entering the air is the only answer. Never mind that there is still an ongoing scientific debate about global warming itself, and that some respected climate scientists believe that methane is a better target, California legislators have locked their sites on carbon dioxide.
If it turns out that global warming and ocean acidification are consequences of capitalism's carbon-based energy system, the entire world could end up dead from the external costs of capitalism.
There are ecosystems like coral reefs [at risk] through ocean acidification. Those are valuable things that we should protect.
Nothing is as daunting as the threats associated with global warming. That's the biggie. Everyone bangs on about rising sea levels but the real challenge of a warming planet is ocean acidification. An acid ocean spells the end of life on earth.
There are some that feel like human activity is the cause for carbon emissions, and because of that, we need to revert to where we were in the 1870s for carbon emissions. I just choose to disagree with that.
The burning of fossil fuels has altered the amount of carbon dioxide in the atmosphere so rapidly and so abundantly that now, we are driving not just the warming trend, not just the sea level rise that is a consequence of the warming trend that is melting polar ice and alpine ice, but also [ocean acidification].
'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.
Hawaii feels so passionately about climate. You know, our oceans are warming. As a result, we have more ocean acidification and coral bleaching. You can actually see it.
There is no strong evidence to prove significant human influence on climate on a global basis. The global cooling trend from 1940 to 1970 is inconsistent with models based on anthropogenic carbon dioxide emissions. There is no reliable evidence to support that the 20th century was the warmest in the last 1000 years.
Our leaders must get to grips with the huge risk that carbon dioxide emissions pose to the economy and the environment. As we know, carbon dioxide is a long-lived gas. It hangs around.
