Krill are endangered because of global warming. They feed on the algae that live underneath the antarctic ice. If the ice melts, there is no more algae. If the algae's gone, it means no more food for the krill so they will die. If there is no more krill, animals like whales and penguins will die to because there will be no more food for them.

Pollution, overfishing, destruction of the water environment, boat traffic. Sonar, and loud noises might effect water life that have sensitive hearing. Building bridges, and islands in water areas that used to be free and clear. Introduction of harmful species into an area that they are not supposed to be in.

Most crickets are not endangered, but some, such as the field cricket, or Gryllus campestris, have been driven out of their habitats and so are being reintroduced to new areas in an effort to save them.
