Tigers in the future would be way different than most. Since they are predators they rely on their prey: Their prey would decrease over the years leaving them to have to find a way to contain the nutrients for longer. Along with global warming since the sun will become hotter, then their internal body temperature would have to decrease to withstand it. Also, the chemicals in the air would come into contact with their pores, robbing them of their camouflage coloring.
Thank you for your interest in contacting Future Engineers. We look forward to connecting with you!
