Grassroots fundraising means asking many people, usually regular people, to donate a small amount of money towards a cause or organization. It is like asking your friends and family to give you money for a lemonade stand you want to start in your neighborhood.
For example, let's say you want to raise money to help clean up a local park. You can set up a donation box in the park, approach people who use the park, and ask them to donate money to help with the cause. You can also make flyers or posters and put them up around your neighborhood, asking people to donate money to your cause.
Grassroots fundraising is important because it allows regular people to contribute to a cause they care about, even if they can only afford to donate a small amount. Together, these small donations can add up to a large amount of money, which can help fund important projects and initiatives.
