There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.
Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.
Think of the earth as a living organism that is being attacked by billions of bacteria whose numbers double every forty years. Either the host dies, or the virus dies, or both die.
I was too young to be an avid enthusiast for the franchise, but like billions of people I remember as a child sitting around with the family on a Friday night with pizza and popcorn and a 'Die Hard' movie on.
It's a relief to hear the rain. It's the sound of billions of drops, all equal, all equally committed to falling, like a sudden outbreak of democracy. Water, when it hits the ground, instantly becomes a puddle or rivulet or flood.
There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.

Aquatic invasive species are destroying the environment, damaging fisheries, and costing American taxpayers billions of dollars annually.
When cyclones tear up Oklahoma and hurricanes swamp Alabama and wildfires scorch Texas, you come to us, the rest of the country, for billions of dollars to recover. And the damage that your polluters and deniers are doing doesn't just hit Oklahoma and Alabama and Texas. It hits Rhode Island with floods and storms.
Since my childhood, I have always made works with polka dots. Earth, moon, sun and human beings all represent dots; a single particle among billions.
