Scientifically speaking, nature is the physical world and everything in it that is not created by humans. It includes living organisms, such as plants and animals, as well as non-living components, such as air, water, rocks, and soil. Nature can be studied through various scientific disciplines, such as biology, ecology, geology, and physics. It is a complex and interconnected system that follows natural laws and processes. By studying nature, scientists can gain a better understanding of how the world works and how to sustain and protect it.
