What does it mean to "do good"?
One way of defining "doing good" is "having a higher social" impact, where your social impact is given by the number of people (or non-human beings) whose lives you improve and how much you improve them, over the long term. (Source.) This presents a more consequentialist perspective.
Making climate change your mission
We often focus a lot on eliminating personal consumption that contributes to climate change, and forget that different types of consumption harm the world in significantly different ways . It's also worth noting that not driving a car for a year matters about as much for the world as a $20 donation to a highly effective charity.
Trying to change the world, for and against
In 2009, when Toby Ord, an academic at Oxford University, was making less than £30k a year, he declared that he would donate 1,000,000 pounds over the course of his life to effective charities which aimed to alleviate global poverty and improve global health.
