Part A: Conservation of Biological Diversity
Contribution of humans in Species Extinction
Extinction have been a part of the life on Earth. Extinction of a species happens when the
species cannot adapt the changes on Erath and then dies. However, the human existence have
impacted the existence of other wild species (Nyhus, 2016). Five ways that human have
contributed in the species extinction are described below:
i. Climate Change: Pollutions and wiping forests have caused to rise the earth’s
temperature by 1 degree. It results the hotter summers, droughts, floods and extreme
winters.
ii. Hunting: Hunting have been a way for human to wipe out an entire species. The hunted
species are tigers for their skin and bone, leopards, rhinoceros for their horns and
elephants for their teeth.
iii. Deforestation: Humans have converted the forests into cultivating land and cities. It
destroys the habitat of the Animals who were living in the forest.
iv. Technology: Science and technology have caused major harms to nature. For example
the GPS and radio waves are the major cause that the birds and marine animals are near
to an extinction.
v. Interbreeding: The interbreeding are also cause as the species kin is replaced by a new
kind of species that is the hybrid one.
