Are they enough?

I went out with my friends few days back and we passed a cemetery.The cemetery located just next to the road that we took that day.I looked at the cemetery and that question came into my mind..again.Wanna know what was it?Sure.I was wondering, if we die, will there be enough space for everyone?
Let say that there is no more space left to bury the body,then where will the body goes to?As we all know, the price of a piece of land nowadays is very high and plus, most of the lands are meant for development.More houses,more commercial areas and more shopping malls.Then what will happen if there is no more place left to bury our bodies?
I'm worried and feel like there is something should be done in order to avoid such thing to happen. What is the solution for this problem?Yup, this might not happen now,but it will surely do later.Maybe soon.Therefore,we should be worried upon this matter and look for the best solution.We need more lands and the authority should do something about it as soon as possible.If not, we will end up paying thousands bucks just to reserve a space for our body when we die later.
