For us, earth is the only option for now. So far, nothing else in the galaxy is habitable. The earth is big enough to take care of itself and does what it wants, no matter how inconvenient it may be for us. Hurricanes, tornados, floods, droughts, lightening fires, earthquakes, tsunamis and ice ages will happen. History shows that some parts of the world that are now deserts, were once agricultural, food producing plots of land with adequate rainfall. Asteroids have hit the earth in the past and could hit us again. And every 100 years we get all new people.
We may be able to plan for these natural disasters where they are common and we may be able someday to understand enough about how they happen. But it is probable that carbon doesn’t cause global warming, so we shouldn’t spend any money on it. I don’t expect an ice age soon, but I expect whatever warming we get will boost food production.
We should probably build more reservoirs and maintain our water treatment infrastructure and build fire-breaks and clear forests of underbrush to prevent lightening fires from spreading. We should probably try to build earthquake-proof bridges and buildings. We should be careful what we build in areas that are prone to damage of all sorts. We should also continue to develop better materials and building techniques.
Nature also endows us with specific genes that can determine how well we will do in life. We all live on the “normal curve”, so our abilities range from low to high in every field of endeavor. Whatever impediments we get from our natural abilities can be overcome by effort and what we decide to excel in. It takes some thought to choose our course in life. Those who are not doing as well as they like should give it more thought.
