Answer: Humans use man-made products, which leads to a loss in species number and an unbalanced food chain. They are mainly the cause of endangered species, and only species that contain wide variations/diversity are able to survive.
Step-by-step explanation:
Land use change, largely for industrial food production, is the major factor directly responsible for biodiversity loss, accounting for 30% of the global biodiversity reduction. The second major factor, which accounts for around 20%, is overexploitation (overfishing, overhunting, and overharvesting) for goods including food, drugs, and lumber.
