The Red Cross is probably the best known emergency relief organization in the countrybut theyre not necessarily the best. Accusations of mismanagement have plagued their responses to national and international disasters, and their name recognition and easy text message donation system can obscure worthy local and grassroots organizations. As you decide how to support the relief efforts, consider not just where you give but what. Supplies are in great need, of course, but even if an organization has an Amazon wishlist, a straight up monetary donation can allow them to respond with more speed and flexibility. See this Wired piece for more on why. And please dont send unsolicited donations of materials to any organization. Odds are they cannot use it. Dont forget that most nonprofits, even if they organize volunteers, still rely on staff to runmonetary donations help ensure that those crucial employees get paid. Hurricane Harvey continues to barrage Texas, destroying homes and devastating lives. Whether or not Read more Read. Most organizations will allow you to earmark your donation specifically for Harvey relief, but consider making a general donationif funds are needed for Harvey, thats where your money will go, but unrestricted donations allow organizations to respond quickly and nimbly to the next disaster, too. And if it matters to you, check before you donate to see if your contribution will be tax deductible. Guide. Star has a robust guide to deciding where to donate here. If youre local, of course, you can reach out to these organizations about volunteering, too. In the immortal words of Mr. Rogers mom, Look for the helpers. Well, here are a bunch of them National Organizations. Ameri. Cares provides emergency supplies and medical care.
