NEET BIOLOGY

Detailed explanation-1: -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-2: -Destruction of Habitat – It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count. Whole ecosystems live in our forests. It is predicted that all our rainforest can disappear in the next 100 years if we cannot stop deforestation.

Detailed explanation-3: -When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.

Detailed explanation-4: -Unlike previous extinction events caused by natural phenomena, the sixth mass extinction is driven by human activity, primarily (though not limited to) the unsustainable use of land, water and energy use, and climate change.

Detailed explanation-5: -Habitat loss is a consequence of human activities such as agriculture, urbanization, deforestation, resource extraction, alteration of the sea-floor due to trawling (fishing), or the release of pollutants.
