Sen Ruderman, where is the proof

[Haaheo okole puka]

In nature we find poisonous plants everywhere and who's to say they were in previous times not poisonous?
Nature can create poisonous plants with or without human involvement, fact.
Nature cannot work outside its own constructs. Humans can work outside natures constructs and those products when of biological origin are placed in nature will forevermore alter natures constructs. Yes humans are of nature and therefore part of natures plan but nature has equipped humans with internal oversight. To progress forward into the unknown without great exercise in caution is irresponsible. To assume we have mastered complete understanding of natures constructs and can taint nature with our unnatural constructs is pompous irresponsibility.
