Is Lobster worth the eating?

I am a pescatarian, if that word makes any sense. I am a vegetarian that occasionally eats fish. I know I am a hypocrite but that's just what I am!

I do eat lobster every now and then and it is a tasty, pricey treat but today I got myself going on a guilt trip. If you eat a lobster that has been alive for 100 years then it will take another 100 for a new one to grow.

It confuses me that we have not completely killed of these poor creatures yet. How can we keep going, sweeping them out of the sea. 100 years of living for one luxurious family meal. Is that worth it?

Lobster tastes great but life is precious and we often take it for granted.

I wonder if crabs grow quicker?
