Why is an understanding of evolutionary and population processes important for species conservation? Abstract Evolution is it a theory of previous life becoming more like present life over time through means such as "natural selection" With an endless diversity of life‚ and variation as a result of the interactions of organisms with their environments. Fundamental to the process of understanding how evolution works is to look at a combination of many mechanisms such as genetic variation‚

While poaching animals remains the gravest threat to animals‚ trophy hunting has also removed a significant number of animals from these rapidly declining populations (1). There is little evidence that the money is being used to help the threatened species (1). It concludes that trophy hunting may be contributing to the extinction of certain animals (1). My last topic was on Bear Hunts by David Suzuki. 1. Grizzlies are more plentiful now than when trophy hunting was not a thing and it has even been

As humans inhabit more and more of the earth’s land‚ some species of wildlife are more likely to be found in captivity than in their natural habitat. But is that a good thing? Keeping animals captive might not be in our best interest. Caging theses animals up for zoo can be compared to imprisonment for animals. It makes profits for zoos and aquariums while these wild animals suffer. They take away from these animals being free‚ just so they can entertain humans. Lastly it takes away these the freedom
