I encourage you to give to your local food bank which honestly I have had to access many times raising a larger family on a small income. Without other's generosity over the years there are times we would of been in dire straits. I heard a statistic yesterday that was staggering, %40 of America's usable food is wasted. When I'm worried about feeding my family, I wonder how different would it be if just my neighbors cleaned out their food shelves? We never buy in bulk and only for the day, so when life pinches, it gets tough, but we get through and many times because of a food bank.
I have been homeless twice. I know. Once it was the charity of this Catholic church (and being of Protestant upbringing that stretched my heart lots!) and two men who came to the State Park where we lived in an RV and worked that saved us. They would bring food, milk so my little one could have it, but also just so I could have my tea! That made me cry. Gas vouchers so my husband could work. The head ranger unknown to us at the time would drop off loads of firewood when we were just in a tent- 3 kids, 1 cat, one dog because a promised job evaporated. The same Head Ranger who I had made friends with offered me a job hosting and painting the Ranger's houses and office. My husband worked outside the State Park and also hosted and maintained the camp grounds. The Head Ranger moved us around for a year to different sites (when you were only allowed to stay for 3 months), before we had enough to go back home.
List of Possible Charities-
Youth With A Mission- (note this isn't on the Charity Navigator, probably because it's decentralized, meaning it consists of many internationally run bases who are autonomous essentially, but I worked for their bookstore for a couple of years and I was very impressed with them. Choose a country to donate to and look up the base there or a base that ministers to a country you care about. Effective, awesome group that cuts across many christian denominations lines to create a working harmonious group of christian youths ministering worldwide).
Also some food for thought. If you are a knitter and live in a cool climate knit some scarves to give out to the homeless in the winter. One skein of Lion's Homespun, a cheap acrylic that washes well is about $5 (use a coupon!) and knitting a garter stitch at about 20 stitches on size #8 - 10 needle (this is for the Bulky regular Homespun, not Super Bulky) gives you a nice, fast scarf. Don't think expensive wool, it's not an easy wash and it could be scratchy to some. Simple is OK. Also give just $5 dollars- enough for food, but maybe not enough for drugs or alcohol. I've seen some people who create a gift bag out of simple $1 store items. Give socks to homeless shelters- they are the most wanted of gifts. Sanitary napkins and tampons and diapers. Giving doesn't have to be complicated. Just give. PLEASE. A little bit of love can go a long way.
