What is nature? Does it give us a lot for life?

All material objects associated with the existence of living organisms are nature. Water elements and their inhabitants, inhabitants of the earth and everything that happens on it, atmospheric phenomena and outer space. However, everything that is produced by man does not belong to nature. Man takes what is necessary for life from nature. For example, Building houses (trees, stones), food (water, meat, fruits, cereals, vegetables), making clothes and shoes (wool, down, leather and animal skins). Manufacture of various machines and mechanisms (fossils). Nature is also the object of knowledge of its laws. This gives the person the motivation for continuous development and improvement.
