Philosopher Peter Singer cites his top three ethical issues in the world today as: extreme poverty; climate change, which is related to poverty; and the way humans treat animals.
Any rational being should be interested in trying to understand how they ought to live, and whether they are doing things that are right or wrong. Singer suggests asking yourself important questions. When it comes to extreme poverty, ask: “Is it okay for me just to be living my life in my society and not doing anything for people who, through no fault of their own, are living in extreme poverty?”
For climate change, ask how you can put pressure on political leaders to take serious steps to prevent a climate change catastrophe that will disproportionately affect the poor. When it comes to animal cruelty, ask: “Am I complicit in the suffering that’s being inflicted on animals, especially in factory farms but in other forms of farming as well? Am I complicit in that when I buy those products? And, if so, does that mean that I need to stop buying them?”
