CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Many species have become extinct because of hunting and overharvesting, the conversion of wetlands and forests to croplands and urban areas, pollution, the introduction of invasive species, and other forms of human-caused destruction of their natural environments.

Detailed explanation-2: -Species endangerment and extinction have three major anthropogenic causes-overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss. All three causes probably were factors in prehistoric as well as modern times.

Detailed explanation-3: -Habitat degradation or destruction is the single most important threat to wildlife in the modern age we live and the primary cause of species extinction worldwide.

Detailed explanation-4: -The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.

Detailed explanation-5: -When species vanish, benefits to humanity can be lost, too – from economic opportunities related to ecotourism to keeping in check populations of species that can spread infectious disease. The UN report estimated that as much as $577 billion in annual global crops are now at risk from loss of pollinators.
