Habitat destruction

The primary threat to the world’s biodiversity is habitat destruction.
Currently in our world, the humanity is destroying many habitats, people use them in their own purpose, for example, there are a lot of factories instead of the habitats that are destroyed, which are composed by some animal species, plants and so on. In other words, the habitat destruction is a contribute for the reducement of the biodivercity.
In the simplest terms, when a habitat is destroyed, the plants, animals, and other organisms that occupied the habitat have a reduced carrying capacity so that populations decline and extinction becomes more likely. Habitat loss alters or eliminates the conditions needed for plants and animals to survive, even landscapes are destructed.
Desertification, deforestation, and coral reef degradation are specific types of habitat destruction. Forests are converted to agriculture and livestock production, coastal development, estuaries, bogs and swamps converted to landfills, dumps and residential areas. These biologically diverse forests support a wide variety of animal, bird and plant life that can't be found elsewhere.

Remember: habitat destruction is one of the major causes that contributes to the extinction of many animal species!
