Habitat destruction is recognized as most significant threat to global biodiversity
Answers
Answer:
Habitat destruction is currently ranked as the primary cause of species extinction worldwide. The destructive environmental changes include more indirect factors like geological processes, and climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution and others.
Habitat loss poses arguably the greatest threat to the world’s biodiversity. Our impact on the planet has never been greater, and human activity has become the dominant influence on our environment and climate. We are inflicting unprecedented changes on the natural habitats on which wildlife depends, through deforestation and destructive fishing, the burning of fossil fuels, industrial-scale mining activities and land-use changes for agricultural expansion. The statistics speak for themselves: in Indonesia alone, over six million hectares of primary forest – an area twice the size of Belgium – were lost between 2000 and 2012. Globally, a third of all forest cover has now been cleared and another 20% has been degraded.
