Although crowdfunding offers a low barrier entry into making change, there are so many things you can do as a crowd without money. You can crowd-volunteer on the United Nation's online volunteer site, or crowd-petition on change.org. You can crowd-map on greenmap.org or even crowd-design on catchafire.org. Not a scientist but you'd like to somehow help find a cure for childhood cancer? You can offer your computer up when it's idle on the World Community Grid so that scientists can do research faster. Money is necessary for many worthy projects, but you can also give with your skills and other resources. What can we do as a crowd to make more change?
