Explanation:

Explanation: Man-made resources are items or substances that have value to human lives that do not  occur in the natural world. Examples of man-made resources include plastic, paper, soda, sheet metal, rubber and brass. These contrast with natural resources, such as water, crops, sunlight, crude oil, wood  and gold. Some man-made resources are nearly essential to modern human life, such as medicines.  Without medicines, vaccines and similar manmade chemicals, many people would become sick and  die. Others are not essential, and only exist because people want them. For example, many pesticides  are man-made resources, and while not essential, their use enhances the lives of many people.
