What do you understand by biodiversity loss?

Explanation

**Step-by-Step Solution:**

1. **Definition of Biodiversity Loss**: Biodiversity loss refers to the decline in the variety and abundance of different species of plants (flora) and animals (fauna) in a particular ecosystem or globally.

2. **Impact on Species**: This loss is characterized by a decrease in the number of species, which can lead to extinction. When species become extinct, the overall biodiversity of the planet diminishes.

3. **Consequences for Climate and Environment**: The reduction in biodiversity affects our climate and environment negatively. Each species plays a role in its ecosystem, and losing them can disrupt ecological balance.
