What the world needs

I think the world needs food and water, these two things are more important than other things, water is the most important because humans can only survive for four days if you do not drink water water water also used for everyday things day and wash his teeth, clean the house and stuff like that.
On the other hand the food humans can only survive twenty days without eating I think this is very important since it is also not very well cared for animals these last years.
