What 'green' career would be best for me? (interest, $20k, major)

[berrycurious]

I'm going to major in environment and sustainability, a subset of geography, in Vancouver. I was going to be a painter originally but have a strong interest/passion in ameliorating the environment as well as the quality of urban living. I am not a very good public speaker and prefer to autonomously, so am not sure being an urban planner would be the best fit.
I also plan to take up this career in the city of Vancouver.
Any ideas?
Thanks!

You can become a park ranger. If you can live off $20k a year, go for it!!

I think your goals are far too broad. Try narrowing them down.
