The Pros And Cons Of Overpopulation

Genetic engineering could potentially create little genetic variation within the human population because individuals would have a similar genetic makeup. Individuals within a population share a gene pool which is the total sum of different alleles within an interbreeding population. Genetic variation is the measure of the different genetic combinations that are in the gene pool and the amount of genetic variation within the population can affect the survival of the entire population, in this case the human population because the environment is constantly changing such as climate change, introduction of new predators or a new disease than the organisms with the favourable alleles will survive and reproduce and pass those alleles onto the future …show more content…

Cities go on for miles without any greenery and are overcrowded, roads look disgusting as there’s so many cars on the road polluting the atmosphere and if the population increases there will be more cars on roads which will cause even more air pollution in the atmosphere which means that plants and other species will die as the atmosphere will be so toxic or it could potentially introduce new diseases or cancers. Wild animals could also gradually die out and become extinct because of environmental destruction because the humans would be destroying their habitats and also due to over hunting animals. Animal hunting is a very popular activity to do and if there is a higher population more people will be killing animals which is another factor that will cause the wild animals to gradually die out. Siberian tigers have been classed by the IUCN as being endangered. There are approximately 300 Siberian tigers left in the wilderness in the regions of China and North Korea and the factors that are influencing the lives of these tigers are due to humans capturing, hunting or the killing of the tigers and habitat loss due to humans constructing more buildings or cutting down trees to use for vital everyday things such as fences, buildings, shelves, desks and books. Overpopulation would start affecting many other animals as well because more trees and land would be used, destroying their habitats and there will also be a higher number of hunters. Overpopulation will also affect the environment because due to the shortage of natural resources, people will create more plastics than ever before. Plastics are used today in everyday items such as plastic packaging, bags and bottles due to the lack of natural resources. These plastic items are getting thrown away into dumps, rivers, beaches and forests on a daily basis and
