I have an idea for you, Kim. There is a group that operates globally -- including in Vietnam -- to reduce starvation and hunger called CARE. Your control over plants might mean that you could help to develop and proliferate strains of food that could help feed millions all over the world, and you'd never have to kill a single weed.

I have many friends in this organization and ones like it, and I am sure they have somebody who would be happy to speak to you, if you're interested. It may not be the most financially rewarding work, but you can go to bed each night knowing you helped make a difference in the world and are helping to save countless lives.

And to be honest, for somebody of your talents, I'm willing to bed they would pay very, very well.

I can even put you in touch with someone who speaks Vietnamese, if you prefer.
And there's no saying you can't pursue other interests, like the one TeleForce put forward.
