Impact of Human activities on Fauna and Flora

Human activities contribute to changes in the observed biophysical environment which lead to reduced land cover. Most of the changes are due to land use activities that human being execute to derive economic benefits from the environment. San Diego is one place that has fauna and flora which have been influenced by the human activities. Such activities affect the fauna and flora by reducing their number. Therefore, this has an effect of altering the composition and form of the ecosystems. This paper delves into the impact of human developments in San Diego in the habitation process of the fauna and flora.

San Diego has one of the most important coastlines in California. Along the coastline, there are different fauna and flora that depicts the importance of the coastline. It has the diverse organism in the habitats. There are different planktons along the coastline of San Diego which provide essential habitats and have led to developments along the coastlines. Several beautiful sceneries have also developed along the coastline. Human activities have led to rising in temperatures along the coast, beach erosions, and floods along the coasts. The effects are the direct impact of human activities which include human settlements, agricultural activities, and other economic activities.

Continued pollution leads to the buildup of pollutants that have the effect of reducing the number of planktons. The pollution is also responsible for changing the cornerstone species in the habitats that lie along the coast of San Diego. The pollution may be as a result of human settlements or as a result of the industrial activities along the coastline. Continued emission in the environment leads to greenhouse effects that have the impact on the ozone layer. This leads to rise in temperatures around the globe. The rise in global temperatures leads to melting of ice which increases the water level.

When the water level rises then there is a possibility of flooding along the coastlines and this also results in erosion along the coastlines which is beach erosion. At the present rate, the global rise in temperature is expected to escalate to 4.8 degrees by the year of 2050. An increase of 4.8 degrees will have several effects that will change the structure of ecosystems and will subsequently alter the structure of habitats. The rise in temperatures will also lead to the gradual change in temperatures and climate systems in different areas. The impact of a rise in temperatures also has a direct impact on the grasslands and wetlands. The rise in sea level may have an impact on the ecosystem by replacing essential species in the ecosystem and impacting on the relationships between the fauna and flora.

The main management measures that can be employed to ensure that the human activities do not impact the habitats include the policy formulation that restricts developments and physical planning activities in the area. Management of emission systems reduces the pollution of the environment due to emissions in the environment. Controlled settlements and treatment of air pollutions are also essential to the management and protection of the environment. Human settlements can also be controlled in the process of managing pollution. In the end, the best management strategies mitigate the adverse effects of human development effects on the environment.
