The correct answer is: A) People no longer feel that they are part of nature.
The statement “Little we see in Nature that is ours” shows us that humans have created their own world separated from nature. The perfect example of this are large cities in which nature is only found in some trees and parks, trees that are placed there for our comfort. Buildings, cars, streets, etc, surround us and we feel safe there, we are used to live in those places in which everything was designed and builded to fulfil our needs. Imagine if someone from a big city was forced to live in the forest, he/she would probably die within days. Some years ago human was probably more connected with nature as he was involved in a more direct way in the production process, if a family wanted to be warm, they had to go to the forest and cut down a tree for example.
