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.

On a "normal" person, Polygraphs have a 70%-90% success rate. Now, the problem is that a lot of people aren't "normal". Some people are naturally anxious or have an anxiety disorder, which can mess up the results. Obese people often tend to sweat more, which will give the sensors bad readings.  So, is it a good tool for finding the truth? In certain circumstances, yes. Is it enough to convict someone of a crime? No.  ^^This There are so many variables, it's hard to make sure polygraphs are working to model standards.

wow this topic is rarely spoken, thanks for sharing it!! [s:p/zxl] 8) 8) Thank you for reading! I think as days go by it gets more and more talked about, but I don't think there can ever be enough said, especially about positive strategies. It seems like we tend to dwell on the worst and not the solution sometimes. Not to mention I don't think there's anything inherently bad about these things.

Ok so some things about my depression are like i found out i had it when i was 10. I might of had it before then but Idk. But like is a good thing i joined kw cause that's how my friend on here like figured out that i have depression and basically made me tell my mom and dad. And like also i kinda wanted to die and stuff and then later i kinda wanted to kill my self. And hurt my self. I kinda did a little bit but like not that much. And so like i had to do this weird therapy that didn't work. And then it kept getting worse and stuff and then like i went to the doctor and got some medicine but like they didn't give me any for almost a year probably until i was closer to 12. But the first one they tried made me like wake up sometimes and basically be really anxious like freaking out so much that i thought i might hurt myself or kinda other people or do things like run away. But it kinda helped the depression during the day and helped me to sleep sometimes better but like also i stopped wanting to do anything. So then i got a different one but it made me dizzy as soon as i tried it basically and so like after 3 days maybe then I spotted. But then i had to wait for them to get out of my system. After that i starred like regular therapy where you talk to the therapist. Like people told me it was bad so i really didn't want to go for a long time, but i went and it was kind of fun i guess like i could say anything and he wouldn't like be mad about me saying it or anything like he didn't judge and stuff. So i did that for a while like 2 or 3 months and i was feeling a lot better from that and some off the things we did. But like since my dad got a new job it has different insurance so i have to switch but we're just waiting to see like if i need to right now Thank you so much for sharing? You're really brave to talk about that, and I know that sharing your story is going to help somebody else. Thank you. :)
