What are the main threats to biodiversity?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What is the single greatest threat of biodiversity?

Habitat destruction is currently ranked as the primary cause of species extinction worldwide.

Which of the following is the most direct threat to global biodiversity?

The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.

What is currently the greatest threat to species?

Habitat loss poses the greatest threat to species. The world’s forests, swamps, plains, lakes, and other habitats continue to disappear as they are harvested for human consumption and cleared to make way for agriculture, housing, roads, pipelines and the other hallmarks of industrial development.

What is the biggest threat to the loss of biodiversity essay?

Habitat Fragmentation

Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.

What drives global biodiversity?

Recent debate has questioned whether biodiversity patterns are shaped by local or continental-scale factors (Borregaard et al., 2020); global drivers include climate trends, latitudinal gradients, evolutionary processes and speciation while local disturbance factors include agricultural activity, erosion, grazing …

Which of the following locations has the greatest species diversity?

Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.
