Question

What kind of threats to biodiversity may lead to its loss?

Answer 1

Hint: The term biodiversity refers to various species of life on earth. So, threats to biodiversity mean damaging or destruction of those various species of life on earth.

Complete step-by-step answer:
Biodiversity means a measure of variation at the genetic, species, and ecosystem levels. Rapid changes in the environment lead to mass extinction.
The common threats to biodiversity are:
Destruction of habitat leading to deprivation of shelter and food for animals. Pollution is considered as one of the main reasons for habitat destruction which results in the reduction and elimination of the population of sensitive species. Industrialization has caused many species to go extinct. Due to the continuous use of biological resources, its measure is decreasing day by day. Disturbance and degradation of habitat include natural disturbances and degradation which are caused by spontaneous jungle fire, pest infection deforestation, and locust attack.
Man-made disturbances and degradation are more severe as compared to natural ones. They include cutting of trees, use of fire for clearing forest areas, a collection of litter, and overexploitation for other economically important products also contributes to the disturbances and degradation which result in a loss of biodiversity.
The increasing temperature of the atmosphere is affecting the environment in many ways such as an increase in sea level, climatic changes, and glacial retreats.
A concept known as the evil quartet is related to the reasons which are responsible for the decrease in the number of biological species. This is indirectly related to the loss of biodiversity. The four main reasons responsible for the loss of biodiversity are loss of habitat, over-exploitation, the introduction of the co-extinction of species and exotic species.

Note: If proper precaution is not taken then we may have to face many environmental problems. One of the examples is the recent incident which occurred in Lisbon where an explosion of ammonia led to many deaths of people and making the land infertile.
