Modern humans have only existed for a relatively short time, and maybe we’d like to stick around a lot longer. But how can we do that?

Figure out climate change.

1．There have been times in the past when it’s been hotter than it is today, and times when it’s been cooler. But there is something different about the past century. As far as we can tell from the record, there has been no time in Earth’s entire history when the climate has warmed so much in such a short amount of time. 2．There are: more frequent and more severe extreme weather events like tornadoes and hurricanes; droughts increasing; more changeable weather, with seasons beginning to lack regularity; and sea level rises. While climate change doesn’t necessarily pose an existential threat to human existence, it surely poses a threat to how we like to live our lives in modern society.

Figure out nuclear weapons.

A single nuclear weapon doesn’t pose a threat to all of humanity, but the thousands of them in the world right now certainly do. 3．Just consider all the “near misses” in recent history, where nuclear war was avoided thanks only to the quick thinking of individuals. We can only try our luck for so long. And one accident can lead to larger scale nuclear conflict. 4．

Figure out asteroids(小行星).

If you want to know the terrible consequences for ignoring space borne threats, just ask the dinosaurs how well it worked out for them. Asteroids have the ability to cause massive extinction events, wiping out vast numbers of entire species. 5． For humanity to make it to the long-term, we need to equip ourselves with asteroid detection and reduction strategies
