Nature

Nature, in the broadest sense, is the natural, physical, or material world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.

Nature has been in existence long before humans and ever since it has taken care of mankind and nourished it forever. In other words, it offers us a protective layer which guards us against all kinds of damages and harms. Survival of mankind without nature is impossible and humans need to understand that.
