10. Dolphins: Endangered Animals
Dolphins are endangered creatures. This is mainly because of us humans. Dolphins
often are killed because of getting caught in fishing nets that are supposed to catch
fish. Also, ocean pollution harms dolphins and kills their prey so they have nothing to
eat. Climate change warms the ocean temperatures and because of this, prey
populations are affected. This affects the ocean food chain and dolphins and other
animals will not have enough food to eat. Overfishing also kills off the food that
dolphins eat. Habitat loss also hurts dolphins. While humans build dams and use boats
to travel, we are taking up the place where dolphins live and we are polluting it. All of
these things are bad for the environment but the good news is, we can help! We can
reduce the amount of pollution being put into the ocean and we can stop overfishing
and only take the amount of fish we need. Take action and remember that dolphins
are living creatures just like us and that we should start caring for them instead of
putting them in harms way.
