…but “how” and why ?

There are several reasons why some species on the earth have become increasing endangered. Habitat loss is one of the primary reasons for endangerment in species today. Natural changes usually happen at a slow rate, only having a slight impact or change on individual species.

Unnatural reasons are those for which we are responsible for. When mankind causes changes to occur, there is little or particularly no time for individual species to respond an adapt to changes in their living environment.

Living in a hostile environment

An introduction of animal species such as, rats, dogs, insects or any other types of species, non-native to a particular environment can carry many diseases. Even mankind are carriers of diseases that will plague an environment bringing great harm to the surrounding area.

Many species cannot adapt to a hostile diseased infested living environment, some start simply disappearing an will go unnoticed an die off.

Populations of organisms can even become jeopardized in danger of extinction, due to changing environmental conditions or predation parameters.

As human population and consumption increase, wild life habitat is converted to houses and highways. Forests are cut down for building materials, fuel and paper. Prairies and forest land are turned into crop land and grazing land for our live stock, and shopping malls stand where wetlands once existed. The damming of rivers to create hydropower has flooded river valleys, making it hard for ocean going fish to migrate.

Is it worth the cost ?

A significant percentage of many habitats in North America that are important for wild life have been destroyed or degraded since the time of European colonization.

Over 50 percent of wetlands are gone, 90 percent of ancient forest in the North West has been logged, and millions of acres of grassland have disappeared.  Habitat loss affects over 2,000 mammal species around the world and is considered the greatest threat to species across the globe.

Human activities cause loss of habitat

The principle cause of habitat loss is human activity. This activity includes the land and resources we use, all of our production and consumption and the waste we discard.

Each human activity contributes to the main causes of species loss:

* habitat loss
* climate change
* invasive species
* pollution
* unsustainable trade
* by catch ( marine creatures accidently caught in nets while fishing for other creatures
* human-animal conflict.

The 2005 Global Forest Resources Assessment by the Food and Agriculture Organizations of the United Nations estimate the rate of deforestation at 13 million hectares. As tropical forest contain at least half the Earth’s species this represents an enormous loss.  Where does it stand today ?
