Activity - Jeremy Jackson

Jeremy Jackson is a coral reef ecologist, in his lecture he talked about how we wrecked our oceans.  There is overfishing, pollution and overheating.  Overfishing is a very big problem in the world, he talked about how in the 50's they did the same thing we do now, they paid good money to go fishing and catch the biggest fish and the difference between than and now for the size of fish is tremendous.  He also showed a picture of coral reef, and there was no fish around, quite odd, when fish are supposed to be swimming all over the place. The reefs are the fishes homes. Pollution and overheating are also very big issues. With pollution he talked about two biological pollutants, they are introduced species and things that come from nutrients. An example for the introduced species would be the killer algae, and an example for what comes from the nutrients would be nitrogen fertilizers. There is also climate change with overheated and climate change isn't always the best thing for environments like the coral reefs and the ocean.  I feel we need to actually do something about how we treat our ocean, its very sad to hear all these horrible things that are happening. Put some more research in to it, and actually come up with a plan to minimize the pollutants going into the ocean, the overfishing we do, and somehow figure out our climate change.
