Chapter 20: Climate change + Ozone Depletion3. This article deals with a global environmental issue.
4. New studies are showing that global warming may cause further problems to human health because of microbes, bacteria, and toxic algae blooms. These risks come along with other risks like death due to heat waves, natural disasters, and diseases like malaria. These hidden risks are being studied by the National Oceanic and Atmospheric Administration. Some of these risks include the contamination of seafood by toxic algae blooms. A specific type of algae called Alexandrium catenella algae produces a poison that accumulates in seafood and can lead humans to have vomiting to muscle paralysis, and sometimes even death. Another effect is that harmful oceanic bacteria could explode. Climate studies have shown that due to global warming wet regions will continue to get wetter and dry regions will become even drier. This will increase desertification and the amount of dust in the atmosphere from places like Africa. A lot of this dust will end up in the oceans, and scientists predict that it "supercharges" the growth of harmful bacteria that ends up in the seafood humans ingest. A last effect is that more sewage will contaminate drinking water.
5. I think that it's good that scientists are studying these other effects of global warming, but there may be other effects that scientists have yet to discover and that is why we need to be very careful and very aware of global warming. We need to make sure we are all doing what we can to prevent global warming from happening. There are so many little steps each one of us can take to prevent all of these negative things from happening. We need to protect our earth as much as possible. We all can pitch in whether it's just changing a light bulb in our homes, or carpooling with neighbors, making sure we conserve electricity and just being aware of all the things we can do to prevent global warming.
6. Supercharge- to charge with an abundant or excessive amount, as of energy, emotion, or tension.
Great articles - especially the Hudson River PCB one!
