Although life is probably widespread in the universe, our pale blue dot, Earth, is the only known place harbouring intelligent life. Even if we manage to stave off extinction by climate change, avoid a nuclear apocalypse and the dangers of runaway AI, biological life on our planet will eventually come to an end in about 5 billion years’ time. What are the astrophysical dangers to life on Earth, and the prospects for life’s survival into the distant future?

If we focus and decode wisely on our ancient text of knowledge we could travel planets and solarsystems

The global population is not almost 9 billion people, it is almost 8 billion people.

Yes, though according to UN estimates we will reach 9 000 000 000 sometime before 2040. So, not very far off. 10 billion sometime just after 2050. Having said that, the growth rate is expected to level out. But considering the fact that by then we will have a global population five times larger than in the year 1900, I really think the planet might struggle a bit. Optimists will claim it will all be fine, but I doubt it.

what a ramble..mate its an easy thing to calculate, take the amount of nano\microplastics we breathe in , eat and drink currently which is around a credit card in weight per week, observe what chemicals they are produced with and what heavy metals and other toxic chemicals vector to it before we intake it and permeate our blood and organs in it and send the whole toxic mess pumping through our brain and other organs, and figure out just how many toxic chemicals we can take before bad things start happening to those organs..any guesses on how much is too much? seems a credit card a week is too much as far as I am concerned and then apply this to every living thing that needs air, water and you will see there is actually no future for any of us..

If it's such an easy thing to calculate, then why don't you provide us with your result?
