Dragonflies do not live for only 24 hours. Dragonflies actually live for at least several months in a larval stage in ponds, and then emerge into adulthood as dragonflies which fly around. In this adult stage, dragonflies live for anywhere between a few days to several months and prey on other flying insects and look for a mate.
Dragonflies live for several moths, depending on the temperature. If it's too cold, they will only live for 'several' weeks, though.
Besides that, they are food for other animals (birds, reptiles, amphibians, etc.) and feed on other insects, including mosquitoes and horse flies.
That's like asking, why is a humans lifespan average 75 years?
However, I can tell you that most of the time larger creatures have longer lifespans, ie
Cat - 20 years
Mouse - 2 years
Pet fish around 3cm in length - 1 year
Amoeba - 1-2 days

That is a folk tale. The adults usually live for several months assuming they don't get eaten or freeze from early cold weather.
A dragonfly can live as long as six months. A mayfly, however, measures its lifespan in hours or days.

Dragonflies can remain as larvae for three to five years before metamorphosing into an adult. Adults typically live for two to four weeks. See the Related Links for more information on dragonflies.

There are not many insects that live less than a few days. One insect that has a lifespan of 24 hours is the Mayfly.
You can't really, they are water bugs when the come out from the water they become a dragonfly. Dragonflies only live for 24 hours, so, if you see a dragonfly dying, don't do anything, it is supposed to happen.
