What caused the second war between Rome and Carthage?

Carthage and Rome were the most powerful powers in the 2-1 centuries BC. Three wars were fought between these countries (264-146 BC), which came to be called Punic. The most bloody was the Second Punic War, which was caused by the fact that the Romans tried to take root in Sicily.
