Lend With Care
This is a really worthwhile cause. You lend money to people in (primarily) third world countries to improve their lives; they repay it in monthly instalments. So, it’s just like putting a sum aside into an account paying zero interest, which is more or less what most banks do. If you can afford to put say, £100, aside to lend to others less fortunate, on a rolling basis, you will be helping them at no real cost to yourself.
