Peoples affects

• 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.

  years to recover from a single touch, it could
  take up to 500 years before the corals return to
  normal stage.
