What is the future of Mankind?

Question

In a few short decades the earth is going to become too hot for us to live on due to global warming, but without enough time to evolve our way out of it, short of finding a way to leave the solar system, what can we do?

Answer 1

First of all, I think it is going to take a tad bit longer than a few decades to heat up the planet to the point of being uninhabitable. Go sit in yellow knife naked in the middle of winter and tell me then how long you think it will take to get the planet to the point hot enough to kill you.

Second, when we do reach that point, I think we will also have devised ways of living in hotter temperatures. I am thinking more of a bio dome type of surrounding. Or somehow force us to live underground.

Lastly, with things like the Kyoto accord helping, maybe we can turn things around with global warming, but only if we get rid of our dependency on fossil fuels.

Otherwise, we are hooped.

Answer 2

I think it is very likely the planet will become overpopulated (with humans) - that has been the trend - especially if there is a genetic breakthrough to prevent aging. We may be one of the last generations living a normal natural life span. Yet catastrophies - especially a major one - can certainly counter that. Fish will become scarce because unlike for crops or farm animals we won't be able to do much to increase their numbers or accelerate thier growth.

There will be less open space and less privacy. Most things people say or do will in some way be recorded. Yet a rural population will persist - some with few modern conveniences (and some not missing them). Most won't want to be anywhere else. The urban areas will become increasingly worse until a certain point.

I am not so concerned about global warming because a large portion of the land is at higher latitudes of the Northern Hemisphere and our ability to adjust to / cope with the heat will probably surpass any warming that occurs.

Answer 3

I doubt the Earth will heat up so much due to global warming such that we'll be unable to survive. Human activities certainly are heating up the globe, but a few degrees over the next century is nothing that we can't handle. The enviromental effects on the other hand due to global warming would make life harder, for example, people living near the coast, as the water level will rise and displace countless numbers of people.

Answer 4

I think our greatest hurdle is being civilised. In the time we have been on this earth we have technologically come a long way.However the way we behave to one another has moved on little since the time of the Neanderthal. The strong crush the weak, country's still at war over religion,oil, politics etc. Assuming we don't nuke each other we are in danger of stalling progress to find another planet to live and the technology to get there simply by the lack of cooperation and team work.

Answer 5

There is no threat for human life on earth for another million years.By that time man will find some other planet where they can migrate.It may be in some other solar system.Space science is advancing fast.Mean while by adopting ecofriendly action we can control global warming.Do not loose hope

Answer 6

The process shold reverse some way. Sometimes the movie "Day after tomorrow" isn't bad after all. But man might evolve if this heating goes on. Going to the outer spave to build colonies will cause more heating, faster, coz the space-shuttles will heat up the atmosphere as they take off.

Answer 7

Too hot for us to live in? Woohoo, have you been listening to Al Gore? I bet he also told you that he invented the Internet and reinvented government.

As long as humans pack themselves into small living spaces surrounded by black, asphalt solar energy collectors and black tar layers on the building roofs, then use those air conditioners to pump the excess heat from inside buildings into the surrounding outside air, our habitations will continue to get hot. But what that does is generate high pressure zones (hot air variety, not the cold air descending thing we see in winter), then skies over cities will still be comparatively clear, in order to accumulate still more solar energy. The cities will indeed keep getting hotter. But we are talking about a few degrees of temperature on the average.

It is a big earth with a big atmosphere and we are still pretty petty insects crawling around on the surface. Things balance out, higher temperatures and CO2 levels help plants grow, using extra energy and pumping out 02 while building those fascinating carbon structures call trees and grass. The oceans will be doing a bigger thing still as more algae, plankton, and kelp convert CO2 to O2 and biomass and more of the seawater gets evaporated into clouds that rain, a temperature conversion process that lowers surface temperatures both ways (evaporation and condensation).

We are in more danger from doing something stupid like letting Iran build a nuclear weapon and attack Israel, which then causes Israel to attack Iran with their nuclear weapon, which then causes Russia to want to attack Israel, which then causes the US to want to attack Russia, which then causes China to want to attack the US--now there's a danger for humanity that involves unlivably high temperatures.

Answer 8

Nanotechnology will be the major breakthrough for humans - using microscopic machines to lieterally take apart polluting agents at the atomic level removing their effects. Also being able to build materials that only exist in dreams, just imagine being able to walk through a wall because the nano-assemblers in it will detect your prescene and rebuild the wall around you as you pass through! Nanotechnology - its the future

Answer 9

i hope it takes more than a few decades to really screw up the planet beyond repair. but our best hope is to stop polluting our home. we could genetically engineer us and other life to be more temperature resistant but we have a long way to go before we can do that. i have always thought that we could find a way to collect the green house gasses we produce and ship them out to mars to help warm up that planet for future colonization. it would be expensive but i think worth it, save our planet and prep another one for colonization. that's two birds with one stone.

Answer 10

Mankind's future will not change until we unite as one body and force the worlds government in to positive action!
