As the graph is not provided, lets try to answer the question generally.
Explanation:
Human activities are known to be threatful and harm biodiversity in several ways.
Humans activities like deforestation results in many species from losing their homes. These species are not able to survive and hence become extinct.
Human activities such as fragmentation cause the genetic diversity to become lowered for organisms of a species. As a result, a disaster such as a disease results in killing all the organisms of a species present in a community.
