We and our aging world.

 At this time the share of the population aged 60 years and over will increase from 1 billion in 2020 to 1.4 billion. By 2050, the world's population of people aged 60 years and older will double. Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. As anyone who has experienced middle age will know, the process of growing old can be extremely hard on the body. Your bones begin to leak calcium, your muscles begin to shrivel, the immune system weakens, and arthritis can set in. Poor posture and balance affect how you move about the world, while cataracts and deteriorating eyesight impair how you see it. Heart problems and declining cognitive function eventually set in as people approach the end of their lives.

The aging worldwide population studies shows that our earth is over crowded with the human population by the year 2050 an aging world 2020 article.

The increase in Earth's surface temperature will cause a runaway greenhouse effect, creating conditions more extreme than present-day Venus and heating Earth's surface enough to melt it. By that point, all life on Earth will be extinct.

Every few years, or maybe even every few months, a new story, speculation, or conspiracy will go viral, claiming that the end of the world is near. Some claims are very specific; others are more too good to be true.

Yet we do not live in a world where myth and mysticism dominate our thinking; we know that we can comprehend all that’s to come using the predictive power of science. Based on what we know, Earth will meet its eventual end, and they’re all going to happen someday. Here is what that is going to look like.

Over time, as Sun begins to exhaust the hydrogen available for nuclear fusion in its core, the Sun heats up and expands, becoming more power as time goes on. After another one-to-two billion years at the most, the amount of energy the Sun gives off will increase to a certain critical point: high enough that the amount of energy hitting a water molecule in Earth’s Ocean during the day will be sufficient to boil it.

As the oceans boil and the atmosphere fills with water vapor, the greenhouse gas effects will take over, causing Earth’s temperature to rise catastrophically. Our planet will be doomed like Venus than like Earth today, becoming totally inhospitable to life on the surface. There will be no living thing on earth Only, perhaps, a few simple organisms will survive high, but life as we know it will end on our world. The complex, differentiated organisms will have come to its natural end.
