Here I go... I think the world would be better if more of it's inhabitants do what they think is best for all of it's inhabitants overall.I think this would lead to a huge decrease of mistreatment of living beings. This could be for example the murder of animals for their meat instead we might wait for the animals to die a natural death then eat them. This is like what some cannibals do to their loved ones to have a part of their loved one inside them. And how about having a ban on light emitters. light is an electro-magnetic wave and I think that the earth losses most if not all it's energy in this way. at the end I will list a ton of items that emit electro-magnetic waves. Then when the sun explodes in the extremely distant future we might decide to use are then useless eye sockets to import and export data on the internet. this would definitely save energy from the keystrokes this is actually is trivial but a little show of increased efficiency. the speed that we communicate would be extremely improved. By the way we probably would use sound to replace electro-magnetic waves. unlike electro-magnetic waves sound waves don't leave the earth this prevents energy loss. THE LIST: Cell phones, remote controls, radio stations, lights, television sets, and microwaves.
