Natural materials are defined as products and physical materials from the natural world. This definition is in contrast to man-made or synthetic materials. There is a wide variety of natural materials that exist, and they can be roughly grouped into two categories: organic natural materials and inorganic natural materials.Continue Reading
Organic materials include animal and plant products; materials like wood, fiber, bark and soil are some examples. Inorganic materials are mineral products like stone, metal and composites like clay. Generally, inorganic materials contain traces of organic materials, and vice versa. Inorganic natural materials are, by definition, unprocessed. Sand, for example, is an inorganic natural material composed of silica and other minerals; glass is a processed synthetic product of silica and other additives. Leather, on the other hand, is a processed material from a natural source. Animal skins are not considered immediately natural, as human intervention is required to process the skins to create leather.
Natural materials are considered by some to be a good source of objects for children's play. Stones, pine cones, leaves, nuts and branches are some of the many materials that can be used. Children can benefit from the outdoor setting in gathering these materials and can use them in counting, pointing, building and sorting exercises.Learn more about Natural Resources

Experts estimate that approximately 80,000 acres of the world's rainforests are destroyed per day, while another 80,000 acres are irrecoverably harmed each day. Experts also estimate that 135 species of various plants, animals and insects are lost per day, totaling 50,000 species per year, according to Scientific American.Full Answer >
Resources that are commonly accepted as being scarce throughout the world include water, food and forests. Oil and natural gas are also growing increasingly scarce. To an extent, however, resource scarcity is contextually subjective. In wealthier places in which people can afford to pay premium prices for resources that may not be in plentiful supply, the shortage is not likely to be felt as severely as in economically deprived locations.Full Answer >
