Human Impact on Biodiversity & Natural Environment All processes on our planet are interrelated. The human race is just a small part of the biosphere, and man is only one of the species of organic life. Over the course of history, men and women tried not to adjust to the natural environment, but make it easy for their existence. Now we realize that every human activity has an impact on the environment and that environmental degradation is dangerous to all living creatures, including human. Biodiversity gives us an opportunity to live a healthy and happy life. It supplies us with an array of products and materials, plants and soils; it contributes to our medical, ecological, genetical and other spheres.
Nevertheless, the amount of the population increases to a very great degree nowadays. The world population has considerably grown for the last 150 years and continues growing at a phenomenal, explosive pace. The growth of the world inhabitants is associated with the increased exposure to natural systems, destruction of habitats that serve as a refuge for many species of animals and plants. Deforestation and desertification areas occur catastrophically fast. Regulation of river flows, different processing of mineral carriers and development of new natural spaces for crops cultivation, pipe-laying, roads building and other forms of economic activity will inevitably lead to the destruction of habitat and loss of the ecosystem natural properties. The reduction of the species’ amount leads to the destitution of the genetic diversity,which is essential to the changing environment. This also applies to domestic animals and crops. The environmental degradation gathers an ever-increasing speed.
Of course, extinction is a normal and natural part of life. Over the history of the Earth, most of the groups of living organisms that had ever existed, evolved and then slowly disappeared completely. However, different species disappeared because of the natural changes in the environment, such as the Ice Age. Nowadays, species disappear at a faster and more dangerous rate for the reason of non-natural environmental changes caused by various human activities. Some of the actions have a direct impact on species and ecosystems. They include:
1. Climate changes.
The ecosystems suffer from the temperature increasing even now, and it turns out to be one of the main problems in the future. Loss of the Arctic Sea ice threats all the human beings with the great effects. In addition to higher temperatures, more frequent extreme weather events, droughts and rainfall changes can be expected to have a significant impact on biodiversity.
It is an overall use of the wildlife species in order to get some benefits for the humanity. Nowadays, hunting, trapping, fishing, and collecting of wildlife species are sometimes done just for sport or for fun. In the same time, we kill a great amount of the living beings which cannot be changed in their ecosystems. Many species of animals and plants become rare. Many of them are vanished. Surely, there are the Endangered Species Acts in different countries, which protect some species that are at stake of overexploitation, and the Convention on International Trade in Endangered Species of Fauna and Flora (CITES) functions to prevent the global trade of wildlife. Anyway, there are many species that are not endangered from being unlawfully traded or overharvested. Continue reading “Human Impact on Biodiversity & Natural Environment” »
