Is it likely that we’ll go extinct? Even though population keeps growing, the rate of growth has significantly decreased since 1968. The population estimates for today differ. However, it is believed by most that it will peak out around the middle of the 20th century and then begin to decline rapidly. The world’s population may be lower than it is right now as early as 2100.
If humans become extinct, towns would collapse, fields will get overgrown, and bridges will fail. Alan Weisman, the writer of the book The World Without Us (published in 2007), which explores what would happen if humans disappeared from the world, asserts that nature will eventually break everything down. Eventually, if it can’t destroy something, it buries it.
Some people believe that humans can still exist after going extinct since we have created non-running cows and lambs. We may even survive a global extinction because of how flexible we are. The majority of the population could likely be saved if there was a decade’s worth of advance notice before an apocalyptic event, allowing people to stockpile enough food to endure years of freezing cold and darkness.
It is nearly a given that humans will develop to live longer lives—lifetimes. The likelihood of being killed by predators and other hazards, as well as mortality rates, all influence how life cycles change. Animals must breed early or may not breed at all when morbidity rates are high.
We should have at least another 800,000 years as scientists believe that contemporary humans have been around for about 200,000 years. Some scientists think we might live for another two million years, or possibly millions. However, other scientists think humans might not exist in another 100 years.
The prediction of how long our technological future would last may thus be derived from statistical data on the outcomes of civilizations similar to our own that existed before us and lived under comparable physical restrictions. The majority of stars evolved billions of years before the sun and may have supported advanced civilizations that have since vanished on their habitable planets. We could have estimated the likelihood of our civilization enduring for various lengths of time if we had historical information on the average lifespan of a big number of them.
This strategy is comparable to calibrating the probability of radioactive atom decay based on the observed behavior of countless similar atoms. By doing space archaeology and looking for artifacts of extinct technological civilizations in the sky, we may theoretically obtain related data. This would imply that physical limitations determine our civilization’s fate.
Evalutaion of human extremes is a difficult undertaking full of unknowables. Every person who reaches the age of 123 could theoretically pass away the following day, just as it is possible that a medical advancement could allow humanity to live perpetually. Our study has used a statistical, data-driven methodology that is more concerned with what will be observed in this century than with unprovable ideas about the absolute limits of life expectancy. According to our findings, just 13% of people will survive to be 130 years old this century, and there is a very little probability that anyone will reach 135 years old. Will we lose our species? Yes, to answer briefly. The fossil record demonstrates that everything eventually goes extinct. Over 99.9% of all creatures that have ever existed are extinct.
