Answer:
The deterioration of the natural environment causes the loss of mobility of birds and animals. The causes of deterioration of the environment are the destruction of the forest, expansion of agricultural land and urbanization.
Deforestation not only causes many plants and animals to become extinct it also causes soil degradation which causes more habitat loss and extinction. Wildlife extinction has a large impact on our world that most people are not aware of.
Ordovician-Silurian extinction - 444 million years ago.
Late Devonian extinction - 383-359 million years ago.
Permian-Triassic extinction - 252 million years ago.
Triassic-Jurassic extinction - 201 million years ago.
Cretaceous-Paleogene extinction - 66 million years ago.
Extinction today.
In the natural world, limiting factors like the availability of food, water, shelter, and space can change animal and plant populations. Other limiting factors, like competition for resources, predation, and disease also impact populations.
Human activity is by far the biggest cause of habitat loss. ... The loss of wetlands, plains, lakes, and other natural environments all destroy or degrade habitat, as do other human activities such as introducing invasive species, polluting, trading in wildlife, and engaging in wars.
