Jackson believes that the marine ecosystems are changing for the worse. Warmer waters is one way that the ecosystems are being altered by human activity. Due to pollution, the water temperature has slowly increased over time causing a change in the ecosystems that once thrived there. Run-off from fertilizers are create massive ares of water where nothing but algae can grow, also known as a "dead zone". Most of the dissolved oxygen is sucked out of the water by the algae, which pushes out other species. This creates the slime that Jackson referred to in the article.
This article and the movie that we watched in class really opened my eyes to how much trouble the marine ecosystems are actually in. Usually, when I think about endangerment, I think about the rain forests and pandas. What I didn't know is that so many aquatic species are threatened today because of human activity. What really surprised me was how much a consumer could do to help the marine aquatic system, even if it's something small like not getting a certain seafood dish because you know that the species isn't doing to well. I was also surprised by how little some governments are doing to try to solve this problem. You would think that they would be more concerned with their people's future, but instead, some seemed focused on how much money they can bring in. I usually don't eat seafood, but when I do, I'll be sure to ask where it came from.
