Question

What are the five major human activities that threaten to reduce biodiversity?

Answer 1

The five major human activities that threaten to reduce biodiversity are habitat destruction, overharvesting, introduction of exotic species, climate change, and pollution.

Step-by-step explanation:

The five major human activities that threaten to reduce biodiversity are:

1. Habitat destruction: Activities such as farming, logging, fishing, and construction of roads and buildings result in the loss of natural habitats for many species.
2. Overharvesting: Unsustainable hunting, fishing, and harvesting of plants can deplete populations of species, especially those that reproduce slowly or have low population sizes.
3. Introduction of exotic species: When non-native species are introduced into new habitats, they can compete with and displace native species, leading to a decline in biodiversity.
4. Climate change: Anthropogenic climate change, caused by human activities such as burning fossil fuels, is predicted to have significant impacts on biodiversity in the future by altering ecosystems and disrupting species' distributions.
5. Pollution: Toxic pollution, such as chemical runoff into water bodies or air pollution, can harm and even kill many species, affecting their populations and overall biodiversity.
