What does the last sentence mean? The place where this was recorded was in fact a gibbon reserve, which is why you can hear so many of them, but in fact the most important noise that was coming out of the forest that time was one that I didn't notice, and in fact nobody there had actually noticed it. So, as I said, this was a gibbon reserve. They spend most of their time rehabilitating gibbons, but they also have to spend a lot of their time protecting their area from illegal logging that takes place on the side. And so if we take the sound of the forest and we actually turn down the gibbons, the insects, and the rest, in the background, the entire time, in recordings you heard, was the sound of a chainsaw at great distance. What does the last sentence mean? Actually this is a subtitle from TED. I can't understand it because there are a lot of commas... Even i don't know what is the subject. word... plz help me...
