Effects of Society on Ecosystems [Type the document subtitle] 11/14/2011 BIO/280 Kalista Andropolis By Jo Jarvis The ecosystem is the basic building block of biodiversity. In the very recent past, humans have taken resources from this planet with reckless abandon. Humans can build bigger better houses, flatter TV’s, and sell every movie ever made to every person on the planet. Humans are never happy with what they have, there has to be something better, and they want it now! We have become that child from Willy Wonka and the Chocolate Factory© that we so despised. Ecosystem Degradation and Loss From human Society A project ongoing throughout the United States has the Army Corps of Engineers proposing that trees within 15 feet of a levee be chopped down. They believe that the trees are hindering the performance of the levees. The removal of the trees will uproot large areas of sand and dirt, adding to the flood problems, disrupts animal habitation and worst of all, removes trees necessary for controlling carbon in the area and adding oxygen. These types of situations are lose-lose situations. Effects of Human Activity on Plants, Animals, and Ecosystem Dynamics Only five percent of the riparian forest remains in the Sacremento-San Joaquin River area. Tearing down all the trees would not only take the habitats away from the animals that need these trees, it would also damage the ground where the trees are torn up and the traffic in the area tearing the trees out. Much of the wildlife in this area would be disrupted and pushed into the residential areas nearby. Chinook salmon would be disrupted in the water as well as the nests of the Swainson’s hawk and the yellow-billed cuckoo (Lake County News Reports, 2011). Conservation and Exploitation The project of removing trees from this one levee could cost $7.5 billion (Lake County News Reports, 2011) to
