Biodiversity loss, also called loss of biodiversity is a decrease in biodiversity within a species, an ecosystem, a given geographic area, or Earth as a whole.
Biodiversity, or biological diversity, is a term that refers to the number of genes, species, individual organisms within a given species, and biological communities within a defined geographic area, ranging from the smallest ecosystem to the global biosphere. A biological community is an interacting group of various species in a common location. Likewise, biodiversity loss describes the decline in the number, genetic variability, and variety of species, and the biological communities in a given area.
This loss in the variety of life can lead to a breakdown in the functioning of the ecosystem where decline has happened. Biodiversity loss is the loss of diversity in an ecosystem. That means that species in that ecosystem start to die because of harmful human activity. If this keeps on going, those species will then go from endangered to extinct, therefore disrupting the natural balance.
Each and every ecosystem is carefully balanced. If you were to take a species out of the ecosystem, there is a risk that the whole ecosystem could fall like dominoes. Biodiversity loss includes the extinction of species worldwide, as well as the local reduction or loss of species in a certain habitat, resulting in a loss of biological diversity.

Did you know that at least 1,000,000 species are endangered because of human activity, and another 1,000,000 have gone extinct? That's a lot of species, and they are all gone because of human activities.
