It is money economy I beleive, PPl want to make money, everywhere in the world. and, they want to make money fast. There are two imple and logical way of making money a) Increase the price of the product: At present ,because of very very competetive nature of the market, it seems industry is bit afraid to do that. b) Decrease the cost of production: This is the behind scene activities. It seems that industries are using less space, less time to the raw product. In this also they cant touch human side because of legal barrier so they are trying in animals because they cant complain. The person who raises the cultivated animals in "inhumane situation" reterns home and loves her/his pets very much; so, for money we sacrfice about everything, forgetting the exception. Wel, the writer of "Planets of Apes" may have successfully indicated this by saying "Human is very strange species, they love their pet very much and do everything possible to its welfare but they kill their brother to get his money/wife...." Enjoy the life
