There is a lot that one could do to combat starvation. What you do depends on such things as where you are, how much time you have on your hands, and what your talents are. But no one is unable to do something. And whatever you can do, no matter how small, must be better than doing nothing.
You can raise money to feed the starving. You can raise public awareness of the extent to which it is rampant. You can adopt an orphan through one of the reputable organizations that provides services to them. You can donate to a faith-based or other charitable organization that provides services. You can dedicate a few hours a month to an organization of that kind. You can write letters to the editor. You can sell your stuff on Ebay and donate the proceeds. Whatever you do will be worth doing.
I have just finished an anthology of 70 poems, including maybe a half dozen song lyrics, that I titled “Poems & Songs for Christ”, which I am now working on getting published. All of whatever profits or royalties result from this are dedicated to feeding the starving. I will give all of it to Christian missionaries who do work in Africa, Asia, and Latin America, including providing meals to widows and orphans in need.
You can make something and sell it. You can get a part time job and donate the income. You can put all your change in a jar at the end of the day and donate it. You can use your imagination, since you know your circumstances and conditions, and devise ways of getting involved that are compatible with your situation.
You can print out flyers and pass them out, encouraging others to get involved. You can set up a charitable organization dedicated to raising funds for the starving. You can go door to door asking for donations for a charitable organization or do it by phone. There are many ways you can participate in this effort.
Think about it. Pray about it. Talk to your significant other or your Momma about it.
But please, do something about it. They really do need you.
