d. Chapter 21: Water Pollution
e. Samples were taken from the coastline of California(near major cities like Los Angeles, San Diego, and San Fransisco) in 2009 and the results showed that high levels of mercury, PCBs and pesticides such as DDT were found in numerous popular sport fish species. The studies showed that 1 one in every 5 fish caught had so much mercury in them that it was dangerous for human consumption. These fish can cause nervous system damage, increase risk of cancer, liver damage and reproductive issues. Another study done five years ago predicted that it is possible that the world will run out of seafood by the year 2050 because of overfishing and contamination.
f. I think this is a very serious issue that people must be aware of. Since the population is growing rapidly and fish is a very big source of protein it is constantly in danger of being over-harvested. I think people should not only cut down the amount of fish they eat but also be aware of the garbage they leave behind. This garbage could easily run-off into lakes and streams and contaminate the fish population, and then they will eat the fish and get serious health problems because of the high levels of contaminants they are ingesting. Children and pregnant women are extremely susceptible to these health problems and they should make sure they know they aren't eating contaminated seafood.
g. Confluence- a merging or flowing together.
