Very science fiction like, but I would love to do away with food. There should be a pill or some injection which supplies all the necessary nutrients to the body. So, you don't have to taste bad food anymore and you are saved from indigestion and unhygienic food items. Gone is the need to raise crops and kill animals. Toilets are gone too and so is the need to brush. Gum disease and teeth problems are history.

All that is needed is to come up with some kind of chemical process which can create such a pill/injection. This wil also save a huge amount of time and free so many of our resources. World will be transformed completely with such a discovery.
