There are so many ways in which the human race can destroy itself that it has become an almost mundane subject. I would like to propose yet another possible scenario, toxicity. Simply put I believe that we have been damaging our environment on a microscopic level for far too long to escape the consequences. Contaminating it with persistent chemicals, plastic micro beads, polyester fragments and other non biodegradable waste. We treat every piece of soft furnishing in our homes with fire retardant chemicals that have already been connected with a massive increase in the number of pituitary tumours in household pets (being smaller they could be an indication of things to come, just like a canary in a coal mine) Our vehicles are damaging the health of our children and consuming petrochemical resources even faster then we can discard them into landfill as yesterday's consumer goods. Since this stuff is already all pervasive in our environment it is in the food chain, the very same food chain that people depend on. I would suggest that the worldwide environment is like a wounded man, staggering along, as good as dead but he just doesn't know it yet.
