The reason as to why there is essentially no waste in the natural world is because;  in the natural world, there is essentially no waste since the waste of one organism becomes the nutrients or raw materials for other organisms. Solid wastes are unwanted or discarded material we produce that is not liquid or gas. Mother nature also has her own waste disposal solutions in place for years. In natures one organism's waste is another's feast. Natures clean up crew includes the decomposers, scavengers and the detritivores and also the process of biodegradation. 
        
             
        
        
        
<span>The cells of our organs change size as a result of physiological changes of situations like aging and diseases which come with it. Diseases put an extra workload on our body’s tissues and organs that cause the cell to get larger.  Many cells grow larger as they undergo repair after inflammation and infection. Cancerous cells get larger because they are working hard dividing and increasing uncontrollably.  </span>
