Discuss the evolutionary significance of death?

Death keeps the population from growing too large and depleting resources. Also, as the body ages, DNA is less likely to repair itself, which leads to mutations. This is part of the reason why older people (those past reproduction age) are more likely to develop health problems. There is no selection for good health later in life, because by the time it becomes apparent the individual is usually past the reproduction age.
 
I would like to build on this. Why couldnt we all just be immortal and it just be really hard to reproduce? Im sure that would solve alot of problems in the world.

Infact, we would probably be alot further along 'the golden path' with all the retained memories that normally get lost when somebody decides to go and have a fatal heart attack.

I'm serious about this. 'Need to reproduce leads to alot of problems we face today.'
 
There is no significance to death, as such, it is just an inevitable.
Cells wear out, organisms that reproduced early and often passed on their genetic material to the following generations, so there is no advantage, in an evolutionary sense, to not dying.
In tribal communities, perhaps those whose elders died early did better than those who needed to feed their elderly, particularly in times of food shortage. So there is a sense of advantage at that level, particularly when competing against other tribes.

What would happen if nothing died? Would natural selection be important? How many new organisms could be born before there was a huge strain on the environment and resources?
