become vegan. donate to oxfam. become an environmentalist.
you could buy a pet and "care" for it. you could buy a human slave and "care" for it. you could take in an unlikable stray and care for it. to really care for something you have to care for the whole of it, at your own expense. commercially supporting taking an animal away from its family, treating it like an object, etc is not caring. it doesn't make sense to want to be actually caring (its at your expense). its very caring to donate to help children living in poor conditions, which are generally far away from me (3rd world countries), but its not the romantic kind of personal caring that people love (you wont see the kids, they wont know you, people wont really want to know that you gave away your money because it makes them look bad - unless you're a company or exceptional person they wouldn't relate to (Bill Gates lol), or have ulterior motives, etc). people want you to be a kind of non-threatening caring that benefits and supports them, and then that lets them feel like they can relax and let their guard down. they like it if they can see you as part of their "tribe". people are wary of selfless acts because they are not sustainable, not at equilibrium. a selfless act is destabilizing. they want a small, personal kind of caring which is symbiotic.
so to that end, give people little gifts. talk to them and listen to them etc etc. i don't really know. that's so not me.
