Do you think the Earth can sustain itself for much longer?

Question

it's kinda scary when you start to think about it.

Answer 1

Can the Earth sustain itself?
Or us?
The earth will be around longer than we will.

Answer 2

yes i think it can because ,Three electrical systems generated in the earth and in the atmosphere by natural geophysical processes are known. One of them is in the atmosphere, and one is within the earth, flowing parallel to the surface of the earth. The third, which transfers an electric charge continuously between the atmosphere and the earth, flows vertically. See Electricity.

Atmospheric electricity, except for that associated with charges within a cloud and lightning, results from the ionization of the atmosphere by solar radiation and from the movement of clouds of ions carried by atmospheric tides (see Ion; Ionization). Atmospheric tides result from the gravitational attraction of the sun and the moon on the earth's atmosphere (see Gravitation; Tide), and, like the oceanic tides, they rise and fall daily. The ionization, and consequently the electrical conductivity, of the atmosphere close to the surface of the earth is low, but it increases rapidly with increasing altitude. Between 60 and 1000 km (40 to 600 mi) above Earth, the ionosphere forms an almost perfectly conducting spherical shell. The shell reflects radio signals back to earth and absorbs electromagnetic radiations approaching the earth from space. The ionization of the atmosphere varies greatly, not only with altitude but with the time of day and the latitude.

Answer 3

The earth can sustain itself as long as the sun is burning, which should be a few million years yet. However, whether it will be inhabitable to human life for that long depends on us sustaining it!

Answer 4

The Earth can sustain itself fine. Whether or not in can sustain us is suspect.

Answer 5

Of course. The earth goes in cycles. It's not like its going to spontaneously explode because of global warming. It's only a threat to the things alive on it, the planet will swing in one extreme and then back. It will be around indefenitely.

Answer 6

It has managed to sustain itself for 4500 million years.No reason it shouldn't continue to do so.We,perhaps,will become extinct.In the next 1000 years unless some sort of peace is reached.

Answer 7

I would say the planet has pretty much gone to Hell now.
It is not the Earth, but the human beings which are screwing up the planet, with chemicals, fossil fuels, trash, nasty and uneducated folks. I don't believe we have much time left. Everyone needs to pray to God to help us through these terrible times.

Answer 8

once you start to realize what the earth is going thru and what people are doing to it in order to accomodate the rapid growth of the population then I say we have about 2 generations if we are lucky

Answer 9

Well the first calander only goes to like 2016 or some where in there.

Answer 10

I would give this planet 500 years max before there will be too many people to feed.
