The knock on effects of biologically active synthetic products are plainly not yet predictable. Current test and assessment abilities only establish a tenuous "not guilty yet" legislative status.<p>How long is it taking to acknowledge that even a relatively inactive material - plastics - produced without restraint, can devastate ocean life and lead to who knows what destruction or disease, when some tiny little marvels eventually adapt to eat them ?<p>We must prioritise employment of natural materials simply and plainly because they are less disruptive to biology and more predictable by the knowledge and observation of their fitness in natural systems and natural history.<p>Of all our industries mass agriculture should be the most careful and symbiotic with environment and biology. Medicine, quarantined lab research, and exceptional problem cases - this is where novel materials and processes belong. Not sprayed across millions of acres and in our loved ones bellies.
