Human Impacts

I went to the Mukilteo beach, which is the beach that is near old town Mukilteo. There is a ferry and restaurants, and fire pits, and a big playground, so on sunny days there is always a lot of people. One human impact on this ecosystem is the docks, though they do provide a home for some barnacles on the poles that keep them stable. All the boats coming in and out of the water could disturb marine life near the shore. The boats could also potentially leak oil or other things into the water which would also disturb the marine ecosystem. The boats also have some noise pollution, but the main contributors to that are the ferry and the train. Which leads me to my next human impact, the train. The train contributes a lot of noise pollution at the Mukilteo beach. There is always one rumbling by and often time the conductor to pull the horn, which is fun for little kids, but is very, very loud. This could have a long term impact because marine animals could want to move away from all of the noise, to a quieter area. I hypothesize that if the noise pollution in the area were to decrease than there would be an increase of marine mammals like seals. To fix these impacts they could have less trains running by, or they could have less boats going into the water.
