How long will the earth last?
The authors of this study estimate that the total habitable lifetime of Earth – before it loses its surface water – is around 7.2 billion years, but they also calculate that an oxygen-rich atmosphere may only be present for around 20%–30% of that time.
What if the earth died?
Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. Astronomers aren’t sure exactly how close the Sun’s outer atmosphere will come to Earth. While the Sun won’t become a red giant for another 5 billion years, a lot can happen in that time.
What will happen in 1 billion years?
All plant and animal life on Earth need oxygen to survive. According to a new study, a billion years from now, Earth’s oxygen will become depleted in a span of about 10,000 years, bringing about worldwide extinction for all except microbes.
What was the first death in the world?

When did people think the world would end?
Towards the end of the second millennium, people around the world feared that the world would end simultaneously with the beginning of the year 2000, or Y2K. This prediction was based on the practice followed by computer programmers of abbreviating year numbers with two digits when developing software. For instance, “1999” would be coded as “99.”
When was the world supposed to end in 2011?
Faced with the wealth of alarmist information available on the world wide web, even NASA was compelled to publish an information page about why the world would not end on December 21, 2012. The world was also supposed to end on October 21, 2011.

How many people died in a third of the world?
In many rural villages, the last survivors moved away, and the village sank back into the wilderness, leaving only grass-covered mounds. Overall the estimate of one medieval observer matches that of modern demographers: “A third of the world died.” That would have meant about 20 million deaths.
Who are the people of the world dying from?
