New Inventions Needed Quickly

Scientists put the emergence of Homo Sapiens at approximately 250,000 years ago but after 200,000 years of living in caves and bopping each other other the head with a club, around 50,000 years ago we got our act together and began using our large brains to make specialist tools, organise our living space, move to less inhospitable areas and about 5000 years ago we developed cities, agriculture and trade.
Considering the dinosaurs were around for over a hundred million years and never invented anything at all and never evolved beyond walking around and eating each other, us humans have not done bad.
We harnessed fire, invented tools, the wheel, writing, telescopes, engines, discovering gravity and split atoms, invented many modes of transport, electricity and came so far so fast that in 1899, Charles H Duell of the patent office announced that 'Everything that can be invented has been invented'.
Mr Duell was obviously wrong as we carried on inventing things to this day but one day will there be a time when we really have invented everything?
Mankind should be quite rightly proud of itself but there are some inventions that still need to be invented if we are going to last as long as the comparatively simpleton dinosaurs.
In our 250,000 years we have undoubtedly caused more destruction to the planet than the dinosaurs did in their entire 150 million years, enough destruction to seriously place the Planet and its inhabitants in peril so we need to invent, and quickly, a way to cleanse the pollution in the very air that we breath and have shovelled into the now poisoned atmosphere.
We have developed, and used, weapons of such destruction that whole cities can be wiped out in seconds and continue to use up the rapidly dwindling valuable natural resources quicker than they can be replaced so alternative resources need to be invented.
Space travel is a necessity as the only planet we have becomes more overcrowded and unlivable so a whole host of inventions are needed to allow us to travel to, and live on, other moons or planets
We are at the mercy of the earths crust with volcanoes, earthquakes and tsunamis so need to be able to control them as well as the forces of the planet’s evermore violent weather and dangerously warming climate.
While fire and the wheel were essential for human life to develop, inventions since have made human life easier and more comfortable so while inventions such as televisions, the Internet, light bulbs and cars are nice, they are not essential whereas the inventions still to come are literally the difference between our life and death.
For all our smart inventions we are at our most highly vulnerable, some due to our natural environment but mostly due to our own stupidity and undoubtedly we will invent even more horrific ways to end human life so while there is still plenty left to invent, we can only hope that our wisdom advances more rapidly than it has so far.
The dinosaurs may not have been the brightest in comparison to humans but they were around for so much longer than us and they were not the ones who put their very own existence and all life on the planet at peril so surely that makes us the simpletons.
