In its widest sense, nature constitutes all physical things that are not human-made. This means that the entire planet and all of its bio-systems which support life are to be considered part of nature. As the heat energy we derive from the sun is part of the natural order, it – as well as the rest of the physical universe – should properly be considered to be a part of nature. Generally speaking, people will refer to the natural world as living environments – known as biomes – whereas the human-made environment is not. That said, nature can be found everywhere, and you will see numerous examples of it in cities with anything from the presence of foxes to the growth of moss being just two instances of it. Humans are a part of the natural order, but a distinction is often made that separates us, usually so that human activity is not confused with that of the rest of the natural world.
