One thing to change the world

I was at the pub with some friends last night and we all suggested one thing which we would like to do to change the world. Here are some snippets:

• Kill all bumblebees - apparently bees becoming extinct would mean the world would end in 4 years. It seems there would be no food left if things went unpollinated by our humble bumble bee. Notably a particularly evil world changing idea.
• Make natural resources free - Our fear was that everyone would start going into the shed making business (you had to be there).
• Have a scheme where you can occupy someone else's body/mind for a week and start to understand what motivates other people - anyone remember that Red Dwarf Bodyswap episode? Genius.
• Put something in the water which makes people want to forgive each other - like fluoride for the soul.
• Make women's football more popular than men's football in the UK - the boys were well in favour of this.
• Render any weapon of war useless when in the hands of someone about to kill - world wars would be decided by boxing matches between people with huge artificially enhanced arms.
• World wide wealth re-distribution every 7 years - so the rich don't just get richer and the poor don't stay poor.

Any more suggestions in the comments box please....
