Andrea K. -- Marine experts are concerned with chemical flame retardants PCB's (Polychlorinated Biphenyls) and that they will be affecting the marine animals, causing their specie to decrease, which they are already noticing a decrease in the orcas. The PCB's have been building up in the oceans, since people used them in World War II. The chemicals were later figured out to harm people, animals, and ecosystems and was banned in 1970's. It's affecting the killer whales because the fish they eat, they feed on polluted prey, and absorb the polluted water. Once the orcas eat their prey, they absorb that polluted water, leading to a decrease in the specie. Studies show that high levels of chemical flame retardants were found in the Northern Hemisphere and the Southern Hemisphere. Dr. Visser, who grew up watching and loving killer whales, she's doing whatever it takes to protect the orcas, and to make sure it does not harm any other marine animals.
It made me a little sad to read this article, i love killer whales, and to read about their specie decreasing left me with a bad feeling. I just think it's suprising that the chemical flame retardants would be affecting our marine life now, but it has been building up in the oceans since we used it in World War II. I'm just happy it got banned in the 70's, but many industries are near the coast, so that could be the reason the chemical flame retardants are spreading through out the oceans more. In a way im glad i read the article, because i doubt i would have heard about it anywhere else, so i can know what's going on with our planet. Im also really glad people like Dr. Visser would go out and try to help and protect our marine animals. It makes me want to do better and help out our world more, i know what's done is done, but i feel like we can help out the animals that really need it.
