When we think about giving help to developing countries, we often think about giving money

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it's far from enough. Ladies and gentlemen, we've got to e up with some better ideas to help them.
I was very surprised, then, when I read about a plan to make cheap laptop puters for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop puter and he planed to produce a lot and sell them to the children in developing countries at a low price after he visited a school in Cambodia. The laptop will be covered in rubber so that it is very strong and won't be damaged easily. The idea is that these puters will help the children's education as they will be able to surf the Internet. By improving children's education they should help people to find their own solutions to their problems in the long term.
Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals at the same time. We will reduce the waste we produce and help others. In other words, we will be able to 'kill two birds with one stone’, and that is always a good thing.
