"If we are to have a chance of avoiding catastrophic climate change, each of us must reduce his or her carbon footprint."
A good start is to reduce the number of "his and hers".

Well there is our problem.

If a highly educated academic can convince themselves that the destructive riots following the death of George Floyd "show human nature at its compassionate best" it proves that political allegiances can negate any amount of book learning or common sense.

This one has it bad. If he has ever applied the math he must have at his disposal he can not possibly believe the scam of global warming, but expresses that belief to comply with the narrative of his tribe.

God help us, & protect us from academics.

Human nature is any characteristic pertaining to our species that distinguishes us from other forms of life. It can be natural or environmentally related or be a cultural or social trait.

The best example of human nature is greed. I do not know of any other life form that shares that trait. How many things can be related to human greed?

Mr O,
The worst and most important, thing related to human greed is the ongoing destruction of the Environment, and hence the planet, our only home.

ateday,

Yes, it is our greed that drives us to destroy the natural environment at the expense of driving other species into extinction.

Christianity is particularly at fault because it declares that God gave man dominion over all over things to be used for his own purpose. Prior to the growth of religious systems there was feminine relationship between people and their environment that maintained a balance between the environment and human activity. The creation of religious systems transformed the feminine / Mother Earth unity to a patriarchal / male dominated system which began to decimate the natural world to the advantage of the human species.

Mr O,
Yes sadly we have this mistaken belief that WE are the most important species and superior to all else.
The sad fact is we are the only animal species wantonly engaged in deliberately destroying our own Environment, our only life support system, for our own selfish wants.
No other animals species does this.
