1) Even the simplest of words can help someone in need. For a person lost in depression and fear, or pain, encouragment is the first step towards optomism
2) We dont nessisarily eat more. If people want to do so much about it then they should grow thier own. I mean the goverment is always like 'yadda yadda we have to help these people this and that' when the reality is if every MP gave up a 1/4 of thier years salary and put it towards national help in Africa it could cure poverty and set up much needed medical treatment stations, contribute to the rebuild of a once proud nation.
3) We do live with more luxuries than we need, but then again, so do alot of people. Again, read above.
