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.

No one is given a gun. A person has to acquire a permit, and then has to buy a gun for themselves.  Okay, yes, mental health is an obvious issue. But it needs to be for specific mental health problems. It can't be just because someone has a mental illness, because many mental illnesses won't effect the operation and use of a gun, or make it more likely for a person to hurt someone else with a gun. I support background checks which would include mental health history, but only if it's done right. Similarly, the guy who killed 49 people in Orlando was taken off the FBI watchlist. This tells me that there are flaws with the way that the watchlist is currently being used. Once that system is redone, then we can restrict those on it from buying firearms. But at its' current success rate? Not a chance.  And it's not about what's necessary...well to an extent it is, but hear me out. Weapons are used for self defense. No matter how many gun laws you have, criminals will still use firearms in their crimes. Citizens require at least an equal amount of protection that criminals use to break the law.  In other words, if you were to be the victim of gun violence, would you rather have with you a knife or a gun? Would you honestly bring a knife to a gun fight?  First of all, I agree with you. Mental health is definitely an issue! But together these issues can be addressed!!!! And as I said earlier, we can control our weapons. The government can create a harder way to get a gun or any weapon. Look at criminal records!!!! Even before getting a permit, or a license, CHECK THE RECORDS!!! This will help prevent these mass shootings.

The amendmant is there for a reason. Weapons are useful for protection. Protection is going to keep us alive. The human population, as a nation, and as a world! If we take away our weapons now we are all dead! We don't want that.  Now, killing 50 people in the Orlando shooting. That is just not right at all. It was not the gun's fault, it was the person. Same thing with the death of Christina Grimmie. Now, I personally believe that we should not take guns away, but we should find a harder process into buying a gun or some other weapon, and we should be trained properly! Look at people's criminal records, look at their other records. I don't care! As long as we still have protection, but less mass shootings! Omg, so true.
