Because you'll run out of air?
Seriously though, you can only stay at certain depths for a certain amount of time due to the amount of Nitrogen (N2) and Oxygen (O2) you absorb as you dive. The deeper you dive, the more gasses you absorb.
Raised levels of N2 can lead to Nitrogen Narcosis, which in itself is thought to be harmless, it can cause divers to do things that lead to accidents, some fatal. Also, the more N2 in your body, the higher the chances of getting DCS as you surface, which is why you need to offgas as you surface, surface slowly and offgas in between dives.
Raised levels of O2 can lead to oxygen toxcity, which can lead to death.
Best stay safe and stay within limits of tables or your dive computer and only dive to the depths you are trained ad insured to dive to.
