A recently formed charity, Educate for Life, is trying to make its name, in a big way. It wants 1 million people to send in 2 p each. Their reasoning is that everyone can spare 2p, it is virtually worthless in its own, but if enough people send it in the it really can make a huge difference.
They are planning to build an 'eco-school' in India with the money raised. It will run on solar and wind energy and grow its own crops. The idea is to show through example that living can be sustainable, but also to provide much needed education to children that normally have no access and whose families, friends and neighbours are stuck in a constant cycle of poverty.
As Kofi Annan said in his 2001 Nobel Peace Lecture, 'Poverty begins when even one child is denied his or her fundamental right to education.' So if enough people send in their 2 pence peices, perhaps there will be a few less children in the world facing this denial.
