These people would come across a beautiful flower on the edge of a calm stream and think... "yea but can it be weaponized?" That violent state of mind should probably be studied with as much enthusiasm too no? because it's producing a being so toxic it has a violent reaction to everything it touches. Nature fights back in its own unique way though. Hopefully it continues to hide it's secrets for a more deserving species on this planet that isn't hell bent on destroying itself as a means of survival. Love your channel though.
