There are a lot of programs, small, grass-roots projects which are making a difference in Third World countries, war-torn, or recovering from war. These aren't projects funded by super-powers or the ones pumping large sums of money directly into the pockets of government officials.
Many of the projects that I will highlight are funded and carried out by small groups, working directly with the people in crisis. One provides wells to communities where children would normally walk 5-6 miles a day to collect a bucket of filthy water. A group of Israelis plant olive trees in Palestinian communities, for the Palestinian people. Another teaches women in African countries to plant trees in an effort to reforest drought-stricken regions.
I'll be adding to the list frequently.
"The purpose of Fotokids is to help small groups of Central American young people from the poorest of barrios develop useful, employable skills as a means to self-exploration, expression, and discovery. Through intensive, long-term, personal relationships with teachers and mentors, participating children learn and use photography, creative writing, and computers as tools to examine their lives, families, communities, and environment."
