Human activities have detrimental impact on some animal and plant species. The primary factors responsible for the loss of biodiversity are the growing need to bring more land under cultivation and the human interference in marine ecosystems. This essay will discuss the causes of this problem and suggest some measures to save biodiversity.
The two major causes of imbalance in the ecosystem are ever increasing demand for agricultural land and aquatic activities. The need to feed the growing population requires more land to grow food. Consequently, this has led to deforestation and extinction of various plant and animal species. Further, activities like oil and natural gas extraction from the seabed might affect marine biodiversity. It may cause underwater temperature to rise and add some impurities into the oceans that might harm certain water species. For example, it is estimated that oil spill accident that happened last week in Atlantic Ocean will affect thousands of underwater species. Illegal trade in forest produce and wildlife are other factors leading to the cause of biodiversity. Many species of birds and animals have become extinct due to excessive hunting and poaching.
These problems may seem unsurmountable; however, there are solutions available. Firstly, technology such as shed agriculture and genetically modified crops should be adopted to increase the yield per hectare. For example, a study revealed that engineered seeds give twice as much yield as traditional seeds. It is also important for the government to create more wildlife sanctuaries, promote afforestation and introduce serious laws against poaching.
To conclude, there are many human activities such as excessive cultivation of land and exploitation of marine life that have ominous effects on the ecosystem. However, there are some solutions available which can be used to mitigate the problem.
