Question

Enumerate the various causes of biodiversity loss and how they impact human lives

Answer 1

Answer:

Habitat destruction is a major cause for biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution and global warming. Species which are physically large and those living in forests or oceans are more affected by habitat reduction.Global warming is also becoming a major cause for loss of biodiversity. We must create economic policies in order to maintain the Earth’s biodiversity and take appropriate measures to protect habitats and species.

Answer 2

Answer:

Hi there!!!

Explanation:

There are 4 main cause for biodiversity loss. they are:

1. Habitat Loss and Fragmentation

2. Over-exploitation for Commercialization

3. Invasive Species.

4. Species extinction.

1. Habitat Loss and Fragmentation:

A habitat is the place where a plant or animal naturally lives. Habitat loss is identified as main threat to 85% of all species described as threatened or endangered. Factors responsible for this are deforestation, fire and over-use and urbanization.

2. Over-exploitation for Commercialization:

Over-exploitation of resources has coasted more environmental degradation than earning. For example; shrimp farming in India, Thailand, Ecuador and Indonesia results in Wetland destruction, pollution of coastal waters and degradation of coastal fisheries. Scientific studies have concluded that cost of environmental degradation resulting from shrimp farming was costing more than the earning through shrimp exports.

3. Invasive Species:

Invasive species are ‘alien’ or ‘exotic’ species which are introduced accidentally or intentionally by human. These species become established in their new environment and spread unchecked, threatening the local biodiversity. These invasive alien species have been identified as the second greatest threat to biodiversity after habitat loss.

4. Species extinction:

Extinction is a natural process. The geological record indicates that many hundreds of thousands of plant and animal species have disappeared over the eras as they have failed to adapt to changing conditions. Recent findings however indicate that the current rate of species extinction is at least a hundred to a thousand times higher than the natural rate.
