Narrative

Breed said she was more than two miles offshore, but the water was 'gross,' and it felt like she was 'swimming through sewage.' She said the experience made her reflect 'on how everyone's been so fixated on sharks and how interesting it is that we are so scared about these animals that live in the ocean and have no interest in us.' 'And how we are more fearful about that than we are about the damage and destruction we are causing to our own home that thereby directly affects us.
