Reduced biodiversity means a future where food supplies are vulnerable (易受攻击的) to pests and disease, and fresh water is  in short supply. If biodiversity 5 impacts  our lives in such big  ways, then our conservation (环保) efforts don’t just benefit the environment, they benefit us, too. One convincing benefit that comes from wildlife conservation efforts is that it ensures food 6 . Wildlife conservation promotes agricultural biodiversity, which plays an important role in building a secure and healthy food system. When agricultural biodiversity is 7 and land  is cleared for agriculture, extensive habitat loss takes place, as well as undocumented loss of species and massive soil erosion (侵蚀).

A number of studies have 10 reduced diversity among mammal (哺乳动物 ) species and overall decreases in biodiversity to an increase in the transmission ( 传 播 ) of animal-born diseases to humans.
