Describe two ways minerals are used by people. Then explain how the increasing human population affects mineral use, and why this could be a problem.

1. Just like vitamins, minerals help your body grow, develop, and stay healthy. The body uses minerals to perform many different functions, from building strong bones to transmitting nerve impulses. Some minerals are even used to make hormones or maintain a normal heartbeat.

2. Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity.

Hope this helps.
