Return of the Sea Otter, return of the kelp beds

[Catherine]

There have been a number of places where they have restored animals to their rightful habitats. The results have been good for the whole ecosystem.

Of course that only works if there are living specimens left. Sadly with the Dodo they are all gone. We will never really know what the Dodo was like and that is sad. It can't even be remembered properly. 

My favorite is the woolly mammoth. I know they went extinct a long time ago, but still I wish I could have seem them.

In North American they wiped out the Passenger Pigeon.

There were so many pigeons and then there were none.

Loss of a species because of human activity has become so common that there is even a term for it.  It is called Anthropogenic Extinction.
You know it is bad when they have a scientific term for it.

Putting animals back and restoring their ecosystems is the least we can do. It doesn't make up for the ones that are gone forever, but it does show a commitment to do better in the future.
