Humans derive all of the resources needed for survival from the earth and that organisms that live on it. For example, humans get oxygen from the Earth’s atmosphere, water from the Earth’s rivers and food by harvesting the planets animals and plants. Additionally, humans derive the raw materials that are used to construct homes, clothing and tools, from different parts of the planet.
The Earth itself does not produce the oxygen humans breathe; instead, plants living on Earth produce the oxygen. In addition to oxygen, these plants form the basis for the food chain that keeps humans nourished. Additionally, some of the natural resources that humans require, such as textiles that can be spun into clothing, come from plants. Humans also eat these plants and some of the animals that eat these plants. Other food resources are harvested from the ocean, such as kelp, fish and shellfish.
Additionally, humans draw a number of minerals, ores and other substances, from within the Earth. These resources are used for a variety of purposes, such as fertilizers and microchips, while others are used to power cars and provide electricity. Humans also use naturally occurring energy sources, such as sunshine, wind and geothermal vents, to help provide power for their needs.
