Hi...I picked
Mexico simply because a friend suggested it. I've been here over 8 years now and call
Mexico and
Mexico City home after falling in love with the country and the city. Just bought my first apartment and my Canadian girlfriend is pregnant with our first baby...that definitely makes this place home!
For safety, the media is making a lot these days out of the drug war happening up along the US border. Don't let that scare you at all. There haven't been any problems elsewhere in the country and all the troubles we read about are happening between the police, army, and drug traffickers and not the general population. Other than that, I find
Mexico and
Mexico City safer than my own Ottawa. I've never had any problems at all and other foreigners I know here have suffered no more than a pick pocket.
I don't know of the eco-living place you mention. You can try googling a few places in the region, starting with Playa del Carmen, Cozumel, Isla Mujeres, Xcaret, and Tulum. Maybe one will pull up the place you're looking for.
For work, I'm in the English education business and all the foreigners I meet here are as well. There must be a way to find work outside of education but I'm not sure where to look. If teaching is your thing, there are lots of opportunities around the country - though less chances of good employment in beach or resort areas.
If you'd like to know more about teaching, email me or message me here through my profile.
