Pros
The mission, which is to try to get forestry, agricultural, tourism, and other businesses to operate in an eco-friendly way and get consumers to buy eco-friendly products and services, is great.
Cons
The Rainforest Alliance is the most unprofessional organization for which I have ever worked. At no other organization were managers so much more interested in comfort and accommodation than in doing things well. At no other organization was there so much of an emphasis on self-promotion over furthering the mission. At no other organization did a meeting break into a half hour discussion of women's clothing or start with the person leading the meeting asking if anyone had any good gossip to share. You really can't expect to have any sense of accomplishment or feel like you're making a difference. You have to accept that you're mostly just going through the motions.
