Its a tough one. Its a bit riskier because the safest thing is to be broadly diversified. Which is hard the less you have to invest. There at least use to be a microloan thing where they pool peoples money to use to lend to individuals in poor countries to buy things that would allow them to make money. sewing machine, bicycle, whatnot. It had this structure where they used the community to sorta police it (loans would not come to the community if payments were not being made). They charged interest enough to make up for any defaulting or such and still make some profit. Besides that there are a variety of moral funds that have specific rules but what they do is based on the fund. some avoid companies contributing to climate change while others avoid alcohol, cigarettes, or gambling and maybe another avoids weapon manufacturers. The thing is from what I can tell its hard to find one that is not investing in something that would be considered bad to another. You could straight up buy stock in businesses you do not think are to bad.
