Ocean Acidification

Ocean acidification. If you haven't heard of it before, get to know it now. It’s more proof that we humans have really screwed up when it comes to taking care of the ecosystem.


Since we started using machinery that needs fuel to run, the pH of the world's oceans has dropped, meaning the water is becoming acidic (too much carbon dioxide). This has horrible effects on marine creatures that make shells or use shells, eat other creatures that make or live in shells, and the animals that eat the fish that eat the creatures that make or live in shells. Hello – that’s us humans.


Scientists have started studying sea life around carbon dioxide vents in the Mediterranean Sea to get an idea of how high levels of carbon may affect marine organisms living in the more acidic waters. The findings are scary: coral was absent and species of algae that use calcium carbonate were displaced in favour of species that do not use it. Snails were seen with their shells dissolving.


How does acidification occur? Carbon dioxide (CO2) becomes dissolved into water (H2O) and binds with it to make carbonic acid (H2CO3). In other words, 2 hydrogen atoms plus one carbon atom plus three oxygen atoms equal carbonic acid.


If you ever used Coca Cola to clean a penny you’ve seen carbonic acid at work. It will eat through that penny if it’s given enough time. That same carbonic acid will also eat through a snail shell or a coral colony.

Watch & Learn

On August 12, 2009, tune in to Discover Planet Green at 10 p.m. EST/PST for a very important premiere of a new show called Acid Test. The documentary – presented by the National resources Defense Council – is all about ocean acidification.


The film is narrated by Sigourney Weaver and, if you miss it this evening, it will be airing on Discover Green Planet throughout August.


In honor of Blue August, Discovery Green Planet will be featuring online content and TV programming about the study of our Earth’s oceans and their hidden mysteries.

This angers me that they made such a big deal out of it. Like DisneyanimeLover said: "I think it's fine to talk about.

Should these things really be taught or talked about in sixth grade? Should the Holocaust? Should Slavery? Should the Civil Rights movement? Because each of those subjects are definitely more inappropriate than the LGBT and what they stand for and yet it continues to be taught by teachers and learned by children in grades as low as fourth grade. Compared to those events in history, the LGBT discussion seems more like The Cat In The Cat than an inappropriate topic. And besides if a student feels they are mature enough to want to boraden their perspective and thoughts then they should be allowed to do it and not be oppressed or told they're wrong because their views differ from the status quo. Should children really be taught sexuality outside of Specs Ed class? Be honest here, none of us would want our kids to go to school and be lectured on the LGBT.  Well, actually that's not entirely true. ^ It depends on the parents. If they are conservatives, then that'll be true. However, they're lots of liberals who wouldn't mind.  My school educates us on LGBTQ+ quite often, and the students don't mind. Most enjoy it. I've only heard one family complain, and they were conservative.  The teachers are people with political and social opinions as well, which makes it hard to teach fairly. What curriculum would there be?
