I watched this film a few years ago, and the picture that sticks in my mind is the guy in Africa watching his beautiful riverside turn into a junk heap. It's shocking and upsetting.
I'm intrigued by your comment about Dyson. My mum has one, and I hate the thing! Even though I'm a Brit and should be supporting our industries - and despite all the hype, claiming that Dysons were going to change vacuum cleaner technology for the better. I think that must be psychological programming! I have a German-made Miele vacuum cleaner that's about 25 years old and works like a dream.
