Step-by-step explanation:
Singer's Principle of Equal Consideration of Interests is a principle that argues for the fair treatment of individuals by taking into account their interests. According to Singer, all beings who can suffer have an equal moral claim to have their interests considered. This means that when making decisions, the interests of all individuals should be given equal weight, regardless of their race, gender, or species.
