Hike4hunger is an international community-led initiative to raise awareness about the global food crisis, build solidarity behind world hunger and encourage new behaviours in both the privileged and underprivileged worlds to close the gap.
Each year, hike4hunger commemorates the UN World Food Day on 16 October by encouraging others to join or initiate personal pilgrimages, symbolic walks of solidarity ending at a place of significance. Participation and financial contributions focus on providing both immediate and long term relief to marginalised communities in Sub-Saharan Africa. (http://www.hike4hunger.org/)
While I was walking in Beirut today, I met hundreds school aged children walking hand by hand shouting "End World Hunger" with hand-made colored flyers!
So if you visit their website, you can actually plan your own hike in order to raise money and spread the word.
