Larry, so you understand the significance of the problem- the pending extinction of elephants and rhinos, but you want to make zero sacrifice to do anything about it?  

Many poor Africans argue they need to kill elephants to make money- and none of these Africans are getting annual Permanent Fund Dividend checks, or the numerous other welfare benefits that are doled out in Alaska.

There have been many cases where walrus have been illegally slaughtered in Western Alaska- only to take tusks.   A recent, vile case involved the killing of many walrus with semi- automatic weapons, and the only thing harvested were the tusks. 

Where do you think the Chinese are going to turn when they can no longer illegally import elephant and rhino ivory due to loss of these animals?

And you do understand walrus are under significant threat due to the loss of sea ice?

No

Could you clarify, something for me? If a person is born with a penis and testes, it is male, right? And if a person is born with a vagina and a uteris, it is female, correct? As far as I know, the physical attributes each human is born with is not a matter of choice. After birth, humans have many years to make a decision as to what their sexuality will be or even may be born understanding what their sexuality will be at sexual maturity. Some may even identify as being a different sex than at birth. I agree that there are perhaps lesser or greater variations of bi-sexuality that permeate all human beings to a lesser or greater extent. The exploration and discovery about ourselves continues and will be either exciting or dreaded, depending on your views and experiences.

Yes
