Gross Overpopulation Is One Issue That Is Suicide For Any Politician To Address. We Are In Crisis.

If we colonize in this star system and Earth gets swallowed by a black hole, all of the star system goes with it. So colonization within the star system would be futile.

The nearest star system that can maybe support life or has life is around 3.6 light years away (around 20 trillion miles). To get there involved traveling across around 3 light years of interstellar space. Our farthest traveling spacecraft just reached interstellar space outside the solar system, after something like 40 years of travel, traversing interstellar space at that rate would take something like 3,600 years.

Venus sits in the Sun's star system inhabital zone with Mars and Earth. Could it be that Venus developed intelligent life hundreds of millions of years before Earth and it did to that planet what we are doing to Earth? Venus is said to have an atmosphere of Carbon Oxides and sulfuric acid. But, if we choke the Earth with carbon oxides as we are doing, then the acids released in the air by volcanic eruptions potentially concentrate in the atmosphere, after a while, we become another Venus (not that any of us have to worry, our species and every other will long be dead by then).

In essence, we solve our planet's problems, or we accept that everything here will die.
