Global warming has made it difficult for sharks to continue living their peaceful existence. It has also increased the tensions among them and humans. As the temperatures of the water increase, the sharks may move into new locations where they will be more comfortable. This means they can be in areas where people are fishing, boating, and swimming. Sharks have been able to evolve for millions of years. Yet they never had to deal with humans on such a large scale before in order to do so either.
This graph explains how the ocean has been getting hotter at different levels in the water. Thats why sharks cant stay in one spot and feel comfortable because it gets to hot.
