Have you visited art exhibitions? I am sure you have. Every painting displayed is the result of the creators hard work, creativity and passion. Obviously his signature on the painting is a rightful assertion that it is his / her creation.
We, humans, forget that Nature is for the entire life on this Earth, even for the generations to come. Are we not being selfish, in exploiting Her...lets take care of Her as someone in our family, someone who exists for our well being...
