Natural y sintético

The video tutorial explains the differences between natural and synthetic materials. Natural materials occur naturally on Earth and include items like stones, wood, and silk. They can be processed for various uses, such as tanning animal skins or spinning cotton fibers. Synthetic materials, on the other hand, are human-made and include plastics, foam, and nylon. Some synthetics are new substances formed by mixing natural materials, like steel from iron and carbon. The key distinction is that natural materials exist naturally, while synthetic ones are created by humans.
