Understanding Biodiversity Impact

Medium Supporting Details Fact Recall

The following passage discusses the importance of maintaining biodiversity:

Biodiversity refers to the variety of life on Earth, encompassing the diversity of species, ecosystems, and genetic differences within species. Researchers have found that rich biodiversity boosts ecosystem productivity, where each species, no matter how small, has an important role to play. For example, a particular plant might support a specific pollinator, which in turn influences the reproduction of various other plants. Therefore, when biodiversity is diminished, it can lead to ecosystem instability, resulting in harmful effects such as the loss of food sources or increased vulnerability to diseases.

The significance of maintaining biodiversity is further reflected in its direct impact on human survival. Diverse ecosystems provide us with essential resources including food, clean water, and medicinal resources. Moreover, biodiversity contributes to climate stability, as diverse biological communities can better withstand environmental disturbances.
