I saw this message on a shirt today. It was on the back of a shirt a man walking in front of me was wearing. Maybe a cotton shirt, or maybe a synthetic oil based shirt. Either way, it is part of the problem, not part of the solution. You cannot have a world without cancer when you have synthetic running shirts, especially ones that have toxic ink silk screened onto them. You cannot have a world without cancer and have computers, or synthetic running shoes, or stopwatches. What is less damaging to the environment, a blank cotton t shirt or a cotton t shirt with toxic ink on it in the form of the words "Go Green"? The answer: The blank t shirt is less damaging to the environment than the t shirt that has "Go Green" silk screened onto it. You can't have a world without cancer and have synthetic t shirts that say "IMAGINE A WORLD WITHOUT CANCER". You can imagine anything you like, but to actually manifest it, you have to cut out all things that are keeping it from being. Synthetic t shirts that say "IMAGINE A WORLD WITHOUT CANCER" cause cancer. MRI machines, the manufacturing of them, causes cancer. The labs built to test new drugs cause cancer. Cell phones cause cancer. Plastic causes cancer.
