Applying the same statistical approach to extinction data revealed a rate of 100 to 1,000 species lost per million per year, mostly due to human-caused habitat destruction and climate change. Unfortunately, due to their small genetic pool, the species is highly susceptible to a number of diseases and the fertility of the males is gradually decreasing, so they still require human help to stave off extinction.

An endangered species is a type of organism that is threatened by extinction species become endangered for two main reasons: loss of habitat and loss of genetic variation loss of habitat genetic variation is the diversity found within a species it’s why human beings may have blond, red, brown.
Endangered species 1 endangered species 2 the international union for conservation of nature and natural resources have given us a classification of existing plants and animal kingdom based on their characteristics and the threat they are facing due to human intervention and many other specific factors causing their loss: - normal species: species whose population levels are considered to be.

Canada is fortunate to be home to thousands of wildlife species and vast areas of land and water on which they depend unfortunately many of these species are in decline, due in part to human activities there are currently over 600 species of plants and animals at risk of being lost from canada. Human-wildlife conflict is also a major threat to lions due to habitat loss, lions are being forced into closer quarters with humans this, coupled with decrease in their natural prey, causes them to attack livestock. The world has an amazingly diverse number of different species of animal and plant life, but many are in danger of being lost for ever, often as a result of human action an endangered species is a group of organisms which is at risk of becoming extinct.

A species is considered endangered if it is at a risk of becoming extinct, which can be due to a number of reasons, from climate change to human influence to even arguably natural cases factors such as pollution, habitat loss and poaching have led to many animal species becoming endangered. The study of adaptation to human habitats also yields vital information for conservation efforts and helps to soften the environmental impact of business parks, housing, roads and waterways. By 200 years ago, humans, our pets and our livestock had increased from 01% to 10-12% of the mass of the mammals of the earth now, we, our pets and our livestock make up 96% – 98% of the mass of the mammals of the earth.
