Last summer I had the most amazing experience of my life. My dad's an engineer who works with green technology, and he was sent by the university he works for to a small town called Gaviotas in Colombia. Since was on my summer vacation, he decided to take me with him. At first I wasn't ve excited. What was I going to do in the middle of nowhere, in a country where l couldn't even speak the language? And anyway, what was so special about Gaviotas?
