A Sea Change--film on ocean acidification
From Alana:
On Thursday night, a film entitled A Sea Change, was shown at the Bishop Museum. It addressed the much ignored by-product of climate change, ocean acidification. Ocean acidification is, arguably, the most dire consequence of adding ridiculous amounts of carbon dioxide to the air.
For years, the ocean has been absorbing extra CO2 from the air, a total of 118 billion metric tons of it. Adding 22 billion pounds of CO2 to the ocean each day is severely changing the chemistry of the water. But what is wrong with the pH of the ocean lowering by .1, or .01, or even .001? It may not seem like much to us, but any change affects what all life depends on most: the creatures at the bottom of the ocean food chain, namely pteropods. Pteropods are moth-like, transparent creatures, that seem to fly in the deep ocean. They are the food for a myriad of creatures, which in turn are the food source for hundreds of other creatures, that humans then feed on. Increased amounts of CO2, though, are causing the pteropods’ calciferous shells to disintegrate. This threatens the entire food chain.
Scientists have underestimated the magnitude and haste of climate change. They assert that we are past the point where we can stop the extinctions that will come with the disappearance of pteropods and coral. This situation is so extreme that within a few centuries humans could be all but extinct as well. As one scientist simply exclaims, “we’re screwed”.
The thing that disgusts me most about all of this, though, is that we could have solved it by now. It would only cost TWO PERCENT of our GDP to solve the energy crisis. It can be argued that 2% of GDP is a lot of money, but I think it might be a good asking price for ensuring the continuation of our survival as a species, and the survival of the animals we depend on. To put this in perspective, enough photovoltaic cells could have been built to power the entire United States with only $420 billion–HALF of the Iraq war budget.
A big hurdle that the public has to face is simply realizing how much we rely on the ocean, and that it is in fact possible for us to change something that big. Most people accept the fact that the ice is melting, but continually deny that life is endangered because of human activity. One woman in the film says,
“We are a very visual species. What is below water is invisible to us. What we can’t see, we pollute… because it doesn’t exist to us.”
So what can we do about this? The main thing to do is just analyze your lifestyle and make sure that what you do doesn’t add to this serious problem. Venture capitalists have the choice of going down the alley of exploitation as easily as the alley of sustainability. The government owes it to everyone to do something about this. This type of problem will threaten national security, the world food supply, etc, so when is anyone going to do something about this in terms of strong legislation– or creating an actual plan of action?? Depending on your age, you may not see the effects, but it is real. It is not going away. I know that there will not only be a sea change in my lifetime, but a world of change.
