I would unite this world under a common goal that what matters is not how much you possess but how long you can stay on a cosmic scale. I would like us to focus on how long we can stay here and I believe that in order for us to achieve that we must work with our environment instead of against it.
I believe that if we balance our ecological footprint to nature's standards we would easily last more than 15 million years and maybe outlast the dinosaurs. Excluding big apocolyptic events that may or definitly will happen in the long term future. In the past hundred years we have made humongous technological progress and we are on the precipice of understanding the world around us. Imagine how far we would come in ten million years even if you include ups and downs regarding progress. Which is still just a dot on a cosmic scale. But at least it's a dot. With the way we currently handle things we wouldn't even get as close as a spec on a cosmic timeline. Considering that we would only have to balance out our ecological footprint to achieve this makes you wonder what would happen if we were able to not only balance out nature but also use the fundamentals of nature itself to progress the growth and evolution of the environment. To make it livier on this planet, to help nature become more self-sustaining or even create recoures through bio-engineering. We would effectively be able to utilize the forces of nature to also work for our survival. Maybe contributing in amazing ways, like a more efficient magnetic field.
From the perspective of a timeline that stretches into millions of years of technological civilization other problems that must be tackled come into play. How do we protect ourselves against extreme solar outbursts from the sun? How would we survive an ice age? How would we survive an asteroid? To be able to actively think and tackle those problems would not only be amazing and scary but it would also mark our unity as a species. These problems can't be solved if we aren't united. Every individual, every child has a great inventive mind brimmed with idea's, dreams, love and ambition.
I want us to utilize all those talents, all those ideas and see how long we can last. I want us to stay for a very long time. I want to know that when other species look at our planet they are looking at our civilization as it was one billion year ago, when we were still bashing eachother's heads in with wooden clubs. I want them to realize that they are looking at the beginning of a civilization one billion years ago. And I want them to know that if they looked a little bit closer they would realize we are still there.
After those ten days I would step down and I would have wanted to create a world where no one would step up and take leadership. We would all be equal and united under this common goal.
