Availability of food
Great White Sharks are on top of the food chain and are very skilled hunters and thus have an abundance of food available. Their main food sources are seals and sea lions and Great Whites mostly live in areas where they are abundantly available. As Great Whites are able to swim for long periods of time and far distances they are always able to find a source of nutrition.
Another cause that has made it easier for great whites is the protection programs many places have put in place that protect seals and such which leads to more of them around the coastal habitats of the great whites ad thus to a higher abundance of food for the sharks.
