According to baxter, penguins (and all other animals) are valuable only if they provide something for humans.

Anthropocentric Ethics

Explanation:

Anthropocentric ethics are assigning moral values to only humans, or we can say, assigning significantly more value to humans only.

Baxter's anthropocentrism is a human-centered view that is "People or Penguins." According to Baxter, penguins (and all other animals) are valuable only if they provide something for humans. If they are of no use to the human, they are of no use at all. We should adhere to our attention to save the lives of humans instead of animals. There is no responsibility for humans to respect or protect nature for its own sake.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
