Affordable housing, with subsidies for no/low income people. Medical care, addiction care, mental health care. The "best" ways to help seem obvious but unrealistic given the cultural and political landscape. If you mean what can you personally do about a large and politically intractable problem, probably not much. You can volunteer, or donate money to reputable charities. You can vote for candidates that have a realistic plan, if you can find one.
