Why can wild emperor penguins only tell their fortune at the age of 20, but you can live to be 50 when you are raised artificially?

First of all, the predation environment is harsh in nature, and the elderly will become food for other predators, reducing the average life expectancy.

Then there is food. It is impossible to feed penguins selectively according to their physical condition. In the natural environment, you can eat whatever you want, and you will be hungry if you don't eat. When you get older, your body function will be weakened and the efficiency of predation will be reduced. If you eat less, your body function will decline. The vicious circle will naturally be eliminated, and artificial farming will not have this concern, so this is also a part of the factor.

Of course, there are problems between climate and temperature groups, such as fighting and trampling.
