  • Could Yellowstone end life as we know it?

    Best answer: Not in terms of a mass extinction. There have been very many large volcanic eruptions in the past and they didn't cause mass extinctions. The effects may last a few years, but the ash gets washed out of the air within a few months to just over a year. Not long enough to change things very much. A large... show more

    A large Yellowstone eruption will cause disruption of life, but not a mass extinction.

  • What causes wildfires in California? Theres always a fire going on over there.?

    Best answer: It is a semi-desert climate. Has a wet season of variable intensity (mudslides are common in that period), followed by a long dry season. Vegetation gets very dry. The fires are mostly caused by people, both by accident and on purpose. We don't often experience such extreme dryness for extended periods here... show more

The fires are mostly caused by people, both by accident and on purpose. We don't often experience such extreme dryness for extended periods here in the east. We get fires too, when we do, though.

  • Are we over populated? I keep hearing we are. What will happen when we multiply double than what we are now or more?

    Best answer: At various points in human history, we seem to run into the limit of one resource or another. The "green revolution" in agriculture at the middle of the 20th century facilitated a very rapid increase in the rate of human population growth -- from about 0.5% per year throughout the 19th century to over 2%... show more
    Best answer: At various points in human history, we seem to run into the limit of one resource or another. The "green revolution" in agriculture at the middle of the 20th century facilitated a very rapid increase in the rate of human population growth -- from about 0.5% per year throughout the 19th century to over 2% per year in 1960. After that, birth control was probably the main factor in reducing the rate, which now stands at about 1.2% per year. Various regions and countries face severe shortages of water, but technology in the form of desalination has enabled some of those countries to overcome that difficulty. We are rapidly polluting the ocean, both chemically and thermally. Whether that will cause insurmountable problems for humanity remains to be seen. The warming of the oceans is likely to reduce the land surface available for habitation and for agriculture; that could bring about an actual decline of human population...or not! As the human population grows, we continue to extinguish more and more of the other extant species, and that fundamental change in ecosystems is likely to bite us in various ways.

    If the human population doubles, we certainly will not run out of space upon which to stand, but whether food, water, and energy resources can support such a population is simply unpredictable.

  • Are we in the UK responsible for destroying the Amazon Rainforest in Brazil?

    Best answer: I would think that ultimately the government of Brazil is. It is easy and a cop-out to blame the demand source for negative consequences. The truth is that the rainforest is located in Brazil and therefore it is the Brazilian government's responsibility to regulate the harvesting of the countries natural resources. show more

  • Why does the sunlight look different in Winter compared to Summer?

    This is NOT a dumb question at all. Most of the windows in my current apartment face west and since we fell back an hour to standard time almost a month ago, Sun is seems to setting awfully early and awfully far south. This is only my second winter in this apartment, but i miss the rainbows from a lamp with prisms because the Sun is setting to far south to strike that lamp.. The sunlight DOES look and FEEL different. I can't SEE the Sun setting from one west facing window. because part of my apartment is blocking the view... WHERE the Sun rises and sets along the horizon CHANGES throughout the year.

    Yes i did know that about photographs. I suggest you do a google search on "mahattenhenge"

  • Does the Earth consistently create new metals? Read details.?

    Best answer: In general the core doesn't produce new metals such as iron. Material in the mantle is pushed up to the surface and tectonic movements, by means of subduction push the surface down into the mantel and the process is repeated. In other words the earth was into recycling long before it became fashionable to... show more

  • Why does the horizon look slightly curved?

    Is it the curve of the earth? It seems to be too tightly curved to be the curve of the earth. Is it light bending or what?
