There is no good or bad among the life-forms on earth. Each has its role, is necessary, and has equal value.
It seems logical for people to choose something special from nature and use it for the benefit of human beings, but when they do this, they make a big mistake. Taking one element from nature, in the name of creating something valuable economically (cash crops, for example), gives that element special value. It also implies that other elements have a lesser value. When human beings plant only “useful” trees with high cash value in the desert, and cut down the undergrowth referring to those plants as “weeds,” many plant species are lost. Often they are the very plants that are enriching and holding the soil together.
There is no good or bad among the life-forms on earth. Each has its role, is necessary, and has equal value. This idea may seem simplistic and unscientific, but it is the basis for my plan to regenerate landscapes all over the world.
