The Paleolithic was an age of purely hunting and gathering, but toward the Mesolithic period the development of agriculture contributed to the rise of permanent settlements. The later Neolithic period is distinguished by the domestication of plants and animals.

The Mesolithic Period, or Middle Stone Age, is an archaeological term describing specific cultures that fall between the Paleolithic and the Neolithic Periods. While the start and end dates of the Mesolithic Period vary by geographical region, it dated approximately from 10,000 BCE to 8,000 BCE.

People lived more towards lakes and rivers instead of caves, and tree trunks. This led to the change of the jobs of the society. Unlike Paleolithic time’s, man could have more leisure time to spend. This led him to broaden the society he was living in and led to increased populations in the Neolithic Age.

The hydrogen fuel at the core will finally be exhausted in five billion years when the Sun will be 67% more luminous than at present. This marks the end of the Sun’s main-sequence lifetime, and thereafter it will pass through the subgiant stage and evolve into a red giant.

So what’s going to happen in 2045? It’s pretty likely that robots and artificial technology will transform a bunch of industries, drone aircraft will continue their leap from the military to the civilian market, and self-driving cars will make your commute a lot more bearable.

By 2050, 68% of the world population will live in cities, up from 55% today, so the actions of municipal and regional governments are critical. “That’s the future of our cities and the environment. It really depends on how we communicate the climate crisis to the public.”

Life in 2030 will be vastly different due to changing demographics as well. The world population is expected to reach 8.5 billion people by 2030. India will overtake China as the most populated country on Earth. The fastest-growing demographic will be the elderly: 65+ people will hit one billion by 2030.

In the year 1 million, Earth’s continents will look roughly the same as they do now and the sun will still shine as it does today. But humans could be so radically different that people today wouldn’t even recognize them, according to a new series from National Geographic.

Once the fuel supply is gone, the sun will start growing dramatically. Its outer layers will expand until they engulf much of the solar system, as it becomes what astronomers call a red giant.

However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.

The initial concept included an orbiter and small robotic lander in 2018, followed by a rover in 2020, and the base components in 2024. The first crew of four astronauts were to land on Mars in 2025. Then, every two years, a new crew of four would arrive.
