aside from stopping the stupid stinking expensive war that is the death of the republic and the downfall of the empire (didn't ANYBODY learn anything from rome?)
-uh, aside from THAT, we could actually be helping people. here are some projects that take small practical approaches to big problems, and while they don't solve the cause of world poverty, they increase the standard of living for people who really need it.
these people make and ship low-cost wheelchairs to people in developing countries. it's not state-of-the-art-insurance-is-paying-for-it perfect fitted medical supplies, but a lawn chair fitted with bike wheels is perfectly serviceable and a cheap alternative.
and even during daylight hours it's DARK inside a lot of people's homes, where electricity is either expensive or unavailable. these people have come up with a cheap solution that helps.
and while we're at it, the problem of clean drinking water is a major one in much of the world. you don't hear much about this solution to the problem, but i think one of the reasons you don't hear a lot about it is that nobody is going to make a lot of money from it.
and in the developed world, people with diseases like ALS or MS typically can't get access to those spiffy computer-assisted communication devices that would make their remaining days better. those machines are expensive and your insurance won't cover them, so unless you're rich, you're out of luck.
so these guys developed a cheap DIY version you can make yourself or have made for under $100.
