Hello my friends and my dear teacher, today I am going to talk about human threats on endangered species.For example, human activities, like developments, can directly destroy the habitats of native species by cutting down trees for housing, industrial sites, and so on. Moreover, when species lose their habitats, they may pop up in people's living areas often and be killed by cars, or poisoned food.Moreover, organizations of the conservation of species promote awareness of the importance of protecting the environment such as, by decreasing landfill and pollution and providing information about the protection of animals.In other words, the genetic variation depends on many breeding pairs, much fewer breeding pairs can be chosen if the population of species reduces, which causes unhealthy offspring.As a result of this, species lose their genetic variation.
