Make a Difference Day 2009
by Kalee Chau
On October 24, Make a Difference Day, our chapter had a joint event together with Beta Zeta Nu Chapter from Canada College. There were one person from Beta Zeta Nu Chapter(the Vice President of Fellowship, Ryan Calic) and four people from Alpha Sigma Alpha Chapter(two members, Viet Trinh and Tim Avila; the Vice President of Membership, Anis Sohaimi; and the Historian, me). Besides members from our chapters, there were a lot of individual and grouped volunteers from other schools and organizations. One of the volunteering organizations was named 350. In the charge of Save the Bay(a restoration organization), we picked up trash and pulled out aggressive non-native plants(fennel, Russian thistle, crystalline ice plant, and trikia) and put them into decomposable bags at the shoreline along SF3 Pond in Ravenswood (next to Dunbarton Bridge). The event started at 9am and ended at 12pm. It was a good chance not only to make a difference but also to look at the birds and the beautiful scenery there as well as to get educated on the beauty of nature.
The event at SF2 Pond in Ravenswood was part of the south Bay Salt Pond Restoration Project, the largest urban wetland restoration project in the United States. Save the Bay partnered with another organization named US Fish & Wildlife Service at this site to hold this 50-year-planned community-based restoration project, opening opportunities for all the people living in the Bay Area to learn about and protect the Bay Area wetlands.
Before we started the activity, we introduced ourselves and one of the coordinators of Save the Bay, Meagan, gave us an impressive lecture on the Bay Area wetlands. Wetlands are areas where salt water meets with fresh water with rich nutrient. The major photosynthesizes on wetlands are woody plants and bogs. They play an important role in keeping the global ecosystem balanced. Not only do they act as filters before micro- and macro- wastes enter the water body, but they also have an amazing ability to absorb water like a sponge does, effectively controlling floods. Moreover, as the most biologically diverse ecosystem, they provide a large area of nursery and habitat for birds, some herbivores, crustaceans, insect larvae, and other animals because their water body contains high level of nutrient brought in by salt water form the tides, saturated with the incoming fresh water.
The sad thing is that more than 90% of the wetlands around the San Francisco Bay were badly destroyed by human. They were civilized into roads and cities where cars travel around, and people build their buildings. The loss of wetlands has increased the frequency of floods and the damages they bring. Also, dues the the loss of hold of wastes, more toxic and harmful substances have been released into the ocean, polluting the water body and causing serious death among aquatic species. Through the circulation of food-chains, the deadly pollution is in progress of damaging the entire biosphere. Moreover, the wetlands themselves are severely polluted by trash from the road and houses. All kinds of trash was found and picked up at Ravenswood Pond, including liquor bottles, plastic bags, components of shot guns, and other waste plastic tools. Also, the non-native aggressive species introduced from other places by some people have competed and crowded out the innocent native species(such as pickle weeds and gum plants). Those non-native species have no predator at this site. With their existence, the native species will die out soon and so the animals that eat the native species will also die out.
In order to prevent the destruction of biosphere from continuing to happen, we need to make out efforts and do what we can do to save our Mother Earth. Although this restoration project alone is unable to change everything all at once, we believe that if the majority of humans are aware of this fact and bring it into practical action like we do, the biosphere will win the fight against pollution!
