If it is true, that it is the competition between groups which leads to the discord and hatred between us because we believe we are all different, then if people recognized that we were not a different group all this strife should come to a conclusion.
However, when the first rockets were sent into space and sent back the images of our globe, some solidarity was formed between all of the nations which occupy our planet. Yet, that was a fleeting moment in time and easily forgotten.
I almost hate to say it, but what has been proven to work in binding and forming cohesive bonds in smaller groups is presenting them with a common problem or enemy and putting them in a situation where they have to work together to solve the problem.
Extrapolating this concept to the entire planet with all of our varied nations, I have surmised, rather comically, that the only common enemy which could bind us all together is an Alien Invasion. (I only half-joke)
We do however, have a common problem that will take the effort of everyone on the planet to solve. We are just beginning to feel the negative effects of this problem and it has not become so paramount that we as a civilization set aside our differences to face it, yet. That horizon is fast approaching.
These are some of the people culling the information necessary to face this challenge and building the infrastructure when that horizon is at last breeched and we as a civilization are forced to stand in solidarity, or disappear from the history of Earth forever.

THE FINAL CHAPTER
This is a fictional tale and any relation to persons living today is purely coincidental.
Prince Tony said climate change was “crap”, and he firmly believed any changes in Earth’s climate were not caused by human activity.
He was not concerned in our survival on Earth, as our immediate future did not appear to be at risk.
But he was interested in his own survival and immediate future at the helm of his powerful realm.
For him to survive, he must keep his “Powerful Big Business” friends happy by allowing them to continue polluting at a minimum cost to themselves.
He devised a fiendish plan, a solution for the happiness of his “Powerful Big Business” friends.
He would pay them to pollute.
Their continued pollution would not affect the earth’s climate, contrary to the opinions of the climate scientists who had not yet been arrested and imprisoned.
As the years went by, Prince Tony found it harder to breathe, but he was not worried, as all around him had similar problems.
The food shortages had not troubled him either, for there was enough left to feed those who had not yet drowned in the rising oceans.
He had authorised his “Powerful Big Business” friends to cut down and burn as many trees as they wished, regardless of the naysayers and increasing sand storms.
His “Powerful Big Business” friends suggested he not alarm himself over the eastern skies which became darker each day, as this was a minimal risk factor and would one day disappear.
Yet the dark clouds grew, the sun was rarely seen and people died from the cold whilst others starved to death.
Undeterred, Prince Tony, in his infinite wisdom, increased the taxes to raise more money to pay for his food and warmth.
But no monies came, there were no people left, no “Powerful Big Business”, for all had perished in the climate change which he believed was not of mankind’s making.
. . . . and as the dark clouds sank slowly in the west, our lonely Prince Tony finally realized that climate change was not “crap”, it was his plan which was “crap”.
Splendid closing.
Thanks. I have a few climate cartoons here among my political toons if you wanted to have a wander thru.
