So many people I've talked to all of my life (me included) have had the outlook that humanity is some kind of destructive parasite on this planet, missing the point that we've been played into this arena of behaviour. It's not what we are it's what we're being forced to do in a rather heavy handed manner. The idea of us being parasites or as in older dodgy texts 'not worthy' is a rather nifty piece of social engineering and it comes from the mainstream tightly controlled information outlets, then it of course spills into people’s minds and out into grim opinion and conversation. Please don't take my word for it because words can deceive and confound you in a flash, we all have the ability to figure things out for ourselves without becoming lost in blinding belief mechanisms.
