Natural ecosystem is a natural unit consisting of all plants, animals, and microorganism in an area functioning together with all the non-living physical of the environment which plants and animals are dependent upon one another, and their particular surroundings-for survival. Natural ecosystems make up the planet on which we live as well as the entire universe. They are dynamic and interconnected. An ecosystem is a collection of all plants, animals, microorganisms, bacterium, and fungus as well as the non-living components that function together as one unit in a given area (The Ontario Plan, 2011). Living and non-living things intertwine with each other in a natural ecosystem. San Diego’s wetland is an example of a natural ecosystem. In this paper it will discuss about the effects that a growing human population may have impacted on San Diego’s wetland’s resources, including loss or harm to populations of wild species. It would also discuss one management practice for sustainability and conservation of natural resources. Also to identify the risks and benefits of extracting or using one resource from this ecosystem, or in any areas near this ecosystem.
Effects of Human Population Coastal Wetlands are one of many endangered habitat in the world, only next to tropical rain forests. It is said that in the United States there are estimated more than 50% of wetlands have been severely altered or destroyed. San Diego wetland is the most threatened resource on the California coast. By 1900, wetlands have been affected by human activities. Wetlands everywhere have been filled in for human developments such as housing, industrial plants, and airport. They have been dredge for use as canals, waterways, and marinas. Highways are over the streamside canyons and cut right through coastal marshes, causing habitat fragmentation (Sea World, 2002).
Loss and harm to population of wild species
Between 1990 and 2000 wetland loss was
