Pros
One of the best places/positions I can imagine for breaking into the field of conservation, be it in science or comms. You will be hard pressed to find somewhere equal in terms of ecosystems, biodiversity, access to cutting edge research, the sheer amount of projects to work on, and a direct line to a stellar network of scientists, conservation leaders, and innovators in the field. There is also an incredible potential for growth in any position and freedom to pursue your own projects, publish your own papers, or present your own films. Part of the internship also mean living in a remote biological station, which in itself is an incredible life experience. It's not often you will be that immersed in nature. And still, having lived in several different research stations around the world, this is by far the most comfortable I've ever been.
Cons
Some might say that the discomfort of the remote rainforest is a con, but it's also the most wonderful and unique part.
