How do humans reduce diversity in ecosystems?

Answer 1

Humans reduce diversity through a number of ways. First and foremost, the blatant destruction of habitats such as the deforestation of rainforests can reduce the number of species in an environment, but also reduce the number of potential mates, cutting genes available in the gene pool, reducing biodiversity. This can also be caused by over-hunting, polluting water supplies and removing food sources in the area, meaning more animals will die.

Not in an ecosystem, however, we reduce diversity through things like selective breeding. For example the pedigree breeding of dogs has led to a tiny gene pool for each breed resulting in a lot of inbreeding. The same is with cattle as farmers try to make the best cattle they can.

Answer 2

Humans reduce diversity in ecosystems through activities such as deforestation, pollution, introduction of invasive species, overharvesting of Natural Resources, and habitat destruction. These actions can lead to the loss of species and disruption of ecological balance, ultimately resulting in a decrease in biodiversity within the ecosystem.
