Human impact on biodiversity and ecosystem loss
The English College in Prague
Biodiversity and ecosystem are crucial issues that have an impact to the human well-being now and in the future. Biodiversity depends on many factors but the most influentive is the habitat loss which influences the biodiversity worldwide. Humans converts native areas into agriculture and industrial areas without realising how much impact it has now and will have in the future. Habitat loss is connected with fragmentation which influence the increasing amount of extinction. The specific climate is essential to be maintained for some species. If it is changed some species may not be able adjust to new conditioins such as extreme weather conditions like drought or flooding and long term changes in water and air temperature. It causing species to die out. It is a huge threat for the ecosystem because every specie is dependet on another one. Another global threat are alien species that become invasive and suppress the native habitants. In addition, species dependent on the suppressed ones will have to adobt or they will become extint.
Out of the 44, 838 species living on the earth, 905 are already extinct and 16, 928 are listed to be endangered and possibly become extinct. Aaet-asean. Retrieved from: http://www.aaet-asean.org/upload/Ear%20Choung%20Chhay-%20Essay.pdf
Considering that many species are not officially assessed on the list, there are probably many more species that does not exist any more. Most of the extinct species died out due to the human activity. The most serious causes of extinction are habitat loss, alien invasive species and the global climate change. In this essay, I will discuss the human factors that are causing the extenction of the species.
Habitat loss and fragmentation are the largest cause of biodiversity
