Q: Evaluate the impact of humans on evolution in society and the environment. Compare Darwin/Wallace and Lamarchin theories of evolution. Discuss how society has reacted to these two theories.
A: Humans have had a great impact on Evolution in most aspects. An example of this is the destruction of many factors favourable for evolution. The most prominent is the clearing of land by farmers etc. This can have many negative effects on the environment, when land is cleared many things are effected, Firstly plant life can be destroyed, this effects the natural ecosystem also the clearing of land can effect animals, due to the recourses they need being destroyed with the clearing. In the long run this can cause many problems to the ecosystem, one of the most drastic being the extinction of plants and animals alike. Another downside of the clearing is that it reduces the variation in species because they all need specific features to live without the things that have been cleared, with in turn means that it reduces biodiversity. Another factor is with the tampering of Bacteria growth humans have made an impact on the growth of these organisms, now while they are able to help us in our day to day lives they have also become a danger to people if given the right conditions.
These factors have affected both society and the environment, firstly the environment has to pay because land is cleared and it is affected. Secondly there is an impact on society, because now such things as bacteria can affect people and it has been a burden too many societies especially in third world countries.
There have been many opinions on the topic of Evolution over time, however there were three people whose theories stood out over the last few centauries. Firstly there is Darwin, his basic idea was that there had actually been evolution on earth, while this seems like a simple idea. At this time period it was believed...
