Over one-half of the world is at high or medium risk from human disturbance, this often leads to a sickness where corals come diseased or bleached. People noticed a spread of damage and bleaching in coral reefs, this happened not only in places with lots of human movement but in undisturbed areas too. Motor boats can tear up sea grasses in shallow lagoons.
Careless snorkelers come break and damage corals by standing on or leaning against the reef. Even a light touch can destroy the animals living in the hard bodies.
