Present threats have to do with what we humans are doing to the
environment. First, pollution. There is an increasing concern that sea
pollution may be not only displacing whales from specific habitats but also
weakening their immune system and making them more prone to infectious
diseases. Also there is concern that "noise" pollution (ships, oil
platforms, drilling, etc.) may affect these animals that depend so much on
sound for communication. Most efforts are being concentrated on studying
these problems of which we know very little.
