With the effects of global warming and fewer natural resources, how much longer can Earth sustain human life?

Answer 1

It will sustain human life for a long, long time. However, life won't be like we know it now. If we don't figure out a way to use energy such as wind and solar in an economical manner soon, we may be forced to figure it out when we're not ready. Which would, in-turn, cost us even more money.

Answer 2

The phrase "sustaining human life" can span a lot of concepts.

If global warming isn't stopped/reversed, life as we know it now will be quite different.

By the end of the century, we could lose half of the species on the planet. However, insects will increase dramatically, causing more outbreaks of insect-born diseases.

Humans will struggle to survive in a changing environment. Migrations will occur, putting strain on other countries. Wars could break out over resources.

If the ice caps disappear (which hold 75% of the world's fresh water), drinking water could be difficult to find.

I do believe we're going to solve this problem; the question is when.

Answer 3

There is no such thing as global warming. There may be some "debate" but none of it is legitimate. The science of the matter proves conclusively that it does not exist. It's also rather dramatic. The evidence so far contradicts global warming that it is quite obviously a lie. People who say there is global warming, if they aren't totally ignorant of the evidence, are just lying for political reasons.

However, you can't deny the science. When measured, global warming is a no show and rather dramatically so.

Answer 4

natural resources nothing to do with it except the mess
earth can sustain human life for approx 4.3 billion more years or so.
problem is the humans themselves
set in ways to much with money, growth, consumer, etc
need change complete way do things.
very easy if man really wanted too
but very few control the lot and care little if at all,
grass still grow and food still available even without money and current economic structure.
current model dead end

Answer 5

Indefinitely.

For every problem we create, we can come up with a technological solution for it. For example, scientists are already looking into genetically engineering plants that would suck up massive amounts of carbon dioxide and filter the air. Goodbye greenhouse gases. [Incidentally, this is how the last period of massive global warming in the Paleocene era was resolved: vast numbers of Azolla ferns scrubbed the air clean.]

The only exception will be if we blow ourselves up first, but that's not really the Earth failing to sustain human life, that's more of us failing to preemptively blow up the people who would blow everything up.

Answer 6

Actually, with the Sun and thermo-nuclear energy, the Earth has enough power to sustain humananity indefinitely. Even now we have more than enough power and resources, just American and other western nations are taking more than their share.

Answer 7

think about it. global warming can be good for the human race. place s like artic and antartic and all the extreme northern and southern hemispehere will be warmed up and plant life will grow. sure the sea level will increase but to which level.
anyway it get humans to start thinking about leaving this god forsaken planet of ours and start exploring the stars.

Answer 8

Indefinitely.

Population and technological levels may vary drastically upwards or downwards, but inteligent primates are here for the long haul.

The real question I think, is how long before we genetically alter ourselves to the point that we are not technically human anymore?

Give it a thousand or so years and its all over for Homo Sapiens Sapiens.

Answer 9

a long time

Answer 10

For that to happen it will be in the next few generations.
