it is the environment. environment is the key point to effect the species' development.
One positive impact is that the alien species may be able to control a pest species in an ecosystem. It may also bring social and economical benefits such as the process of reforestation reducing soil erosion.However, the alien species may also have negative impacts on the ecosystem. It may lead to increased competition with native species, reducing the chances of survival for native organisms. Native species may be driven to extinction and this reduces biodiversity. The presence of an alien species may also upset the balance between predators and prey.
Antelopes and wildebeests move into the area.
Climate change can cause various effects. It causes living organisms to move from their natural habitat.
It damaged nontargeted species. Example: Eggshell thinning in birds.
It is a negative effect. The loss of trees in the forest, therefore the loss of forest can result in erosion, loss of habitat, etc.
The effect of human activity is negative against nature (including parrots).
All animals live in the environment, in a niche of the environment called their habitat. Changes to the environment can destroy a habitat resulting in the species comprising that habitat to die out.
Hunting should NOT be outlawed. When properly regulated hunting is beneficial to habitat preservation and well being of the species being hunted. If a species has no predators then it overpopulates. Overpopulation lead to disease and starvation. Poaching has a negative effect on animals but this is already outlawed. People that hunt according to the regulations and buy licenses are the largest contributors to wildlife and habitat preservation funds.

New farmland: positive - increases employment and income of taxes negative - encroaches on the habitat of wildlife and fauna

evolution within a species. the allele frequencies in a gene pool of a population
Obviously enough the effects of rising temperatures is a very bad one on animals in every region. Those animals who in the past weren't able to adapt to a considerable change in the climate and their natural habitat ended up extinct. A species will not have young if it is stressed out by the change brought about. This will have a drastic effect on the population at the time. The rising temperatures are making it more difficult for certain species to find food and drinkable water. If the species is one of the bottom species in the ecosystem it will effect all the wildlife in the area. So if conditions are not altered we will get more and more extinct species.

The tiger's habitat is threatened by deforestation, not so much by pollution and climate change so far.
