My dear friends, look at this site! It's a real good deal, spend some time a day to get food for people who need it! A person needs just 400 gr. of rice a day, it's nearly 19.500 rises, but you can earn it by your mind...your brains! http://www.freerice.com/
Our friends, we've started working in a field of hunger helping. Fortunately it's not so topical problem in Russia, but we must discuss with our kids and students the ideas of supporting people who need it!
