Venusians

Just read recently, in a well known scientific magazine, that Venus could well have been habitable some eons ago. It could have supported life, perhaps somewhat like ours, one assumes. While it's a very hot place now, without water, thus cloud to cool the surface, there is evidence that once when the sun was cooler, life strode, crept or slithered upon its surface. I have a few friends who believe that there is an invisible  twin world next to ours, and that what we do here is echoed there. I hope that it is a better world, better managed and one that takes lessons from our mistakes. I deign to question them further, however. I don't have the kind of imagination that can deal with that idea, but the one about Venus, considering it's only a mere 41 million miles off, intrigues me. It also scares me a bit. With the warming of our planet and the possible, but probable, eventual destruction of our cloud system, there would be, naturally, a decline in our own human habitability. We can't live long without water. While, in  our flimsy minds,  the time frame in eons, is almost unimaginable,  we have to remember how  a few decades ago, computer renditions of Jupiter were only a dream. But now, in my lifetime, at the beginning of which,  no one had microwave ovens, home television or cell phones, let alone being able to view space walks, there is no predicting what could be discovered next. It's a most exciting time we live in, and when money can be spent more on advancement scientifically, rather that wars, who knows what is to be?  Sci Fi writers toy with apocalyptic endings of earth in film and text. They see human life as grinding or frying to an eventual halt. The characters in these stories, strive to use whatever bits and pieces of what's left over from our once productive efforts to remake, invent and thus survive.  How long can we use up all means of energy sources to feed our need for commerce, entertainment, transportation and healing, before they deplete?  Old metal junk and defunct electronics become the fodder of the imaginary scenarios in science fiction  films, but the realities may be around that distant corner. Inventors strive to find ways to draw on solar, wind and water power as well as atomic sources, at the same thinking about what will happen when it all runs out. Will it run out; can it?  From what I've noticed in films such as these, there is no greenery to be found and water is more precious than gold. No clouds, no rain; finally, no people. Ah, we live in good times, but while we love tapping on our computers, watching the Olympics and enjoying our swimming pools, we need to look up at the starry sky and think ahead. Far ahead.
