Question

What is biodiversity loss and why is it a Problem?

Answer 1

The biological variety and variability of life on Earth is referred to as biodiversity. Biodiversity is a term that refers to genetic, species, and ecosystem variation. Because of the warm climate and high primary productivity, terrestrial biodiversity is usually higher near the equator.

Complete answer:
Biodiversity is not evenly distributed across the globe, and it is more abundant in the tropics. These tropical forest ecosystems cover less than ten percent of the earth's surface but house nearly all of the world's species. Marine biodiversity is typically higher along the coasts of the Western Pacific, where sea surface temperatures are the highest, and in the mid-latitudinal band of all oceans.
In terms of species diversity, there are latitudinal gradients. Biodiversity tends to cluster in hotspots and has been increasing over time, but as a result of deforestation, it will likely slow in the future.
The extinction of species around the world, as well as the local reduction or loss of species in a particular habitat, all result in a loss of biological diversity. Depending on whether the environmental degradation that leads to the loss is reversible through ecological restoration/ecological resilience or effectively permanent, the latter phenomenon can be temporary or permanent (e.g. through land loss). Human activities that overstep planetary boundaries as part of the Anthropocene are driving global extinction, as has been proven to be irreversible.
Thus,The rapid loss of species diversity and ecosystem destruction is referred to as biodiversity loss. A self-sustaining ecosystem requires a high level of biodiversity. Ecosystems cannot function properly if biodiversity is lost. It has an impact on its productivity and makes it more susceptible to disruptions. For our survival, we rely heavily on ecosystem services.

Note:
For decades, international environmental organizations have campaigned to prevent biodiversity loss; public health officials have incorporated it into the One Health approach to public health practice, and biodiversity preservation is becoming more mainstream in international policy. The United Nations Convention on Biological Diversity, for example, is focused on preventing biodiversity loss and taking proactive measures to protect it.
