These contain CO2 right? I was just going to use them an example of how hypocritical the attack on SUV drivers is, in respect to contributing to global warming.

im so freaking tired of some peoples opinion about wolfs here in sweden. i have debated in forum about this in swedens largest internet "community", people are upset because wolfs occasionally attacks dogs that are not under supervison by their owners, or their cattle occasionally gets attacked (all this happens on the countryside), and those f***ing morons want to short down the wolfpopulation in sweden, because they are afraid someday they grow to much, would be to less herbivores(those who are hunted by by hunters), and they become a threat to the people in villages because sometimes wolfs are spotted in small villages, talkning about them as they wore a deadly sprea…

I read the post on Global warming and it asks for an Authoritie's perspective! i need good hard evidence that the Global Warming is an actual crisis from rigourous data analysis by someone who has been studying this for years and is not bullied around by media scrutiny blowing every little detail out of proportion until no-one knows what the heck they are talking about. Because i need to know where i stand, for all i know no-one knows. let me tell you what i have heard. Global warming has been going on for 6000 years. in 100 years the temp is supposed to increase .85 degrees - this being due to the groud heat/population theorem Antarctica and many…

Anyone know why holly has spines? is it to deter deer and other animals?

That was on the History Channel recently, did anyone else watch it? The last part had a discussion about global warming and man's possible contribution to it, especially compared to major volcanic eruptions, such as Tambora and Krakatoa. Those were sudden events that caused immediate results, while man's contributions are small in comparison, but steady over a long period of time. They did paint a very dark scenario, tho, of what would happen to the world population if we entered another mini Ice Age. It would be a drastic form of population control, at the very least, and a shift in recorded world history like none other.

After hurricane Rita made landfall, i knew global warming had to be making hurricanes stronger, so i did an experiment. I had two identical containers with the tops of shoe boxes in the water on the "west" side of the containder, i call these continents. There were two fans blowing air towards these continents. I had a reptile heating lamp on each cage warming the water temperature up to approx. 105 degrees F. Syran wrap was placed over each container with a thick layer syran wrap in a square about 9 sq. in. In one of the containers i had a candle lit under the thick layer of syran wrap, in the other i didn't. This put more CO2 in one cage than the other. The results were…

I tried searching for this, but I didn't find anything. If there's already a thread to this effect, just point me in the right direction and I'll be quiet. Ok, so I was thinking: is it not true that cities are the most environmentally friendly habitat for human beings? Consider the evidence, taking New York as an example. It seems to me the two biggest environmental problems that we humans cause are destruction of habitats and the use of fossil fuels. As per the first, while it may be true that whatever habitats once existed on the island of Manhatten are pretty much obliterated, the fact that all those people are living in such a condensed space means that they take …

How does tunneling effect metamorphic and sedimentary rocks?...

This Article Discusses the idea that extinct North American fauna should be "reintroduced" to America by establishing present day relatives from overseas, such as cheetahs, wild horses and asses, even elephants and lions. The point would be threefold... to help increase the populations of these declining species and contribute to conservation efforts to "restore" long lost Pleistocene megafauna and North American biodiversity and, of course, economically benefit rural America through ecotourism Even though I like it, I think most of it sounds too farfetched and undoable, and the article doesn't bring up any of the potential problems. But does anyone t…

I'm currently doing a bit of biology coursework in which i have to test species diversity against depth of soil on a hill. My teacher says that I cannot use Spearman's rank to calculate the correlation between these two variables, as it is a stats test and somehow not compatible. The way i see it, if i can plot a graph of these two variables, then surely I can find the correlation between them quantitatively? I don't know whether it is his opinion or Edexcel's, but to me it seems wrong. Could anyone help me?

I have a theory about all the earthquakes happening at the moment and wanted to bounce it off a few people to see what they thought??? Does anyone think that all the oil we are removing from the earth does not serve as some sort of lubrication for the tectonic plates??? Would really love to know from someone that knows a little about this. thanks Mooks

I'm a college student studying biogeography this semester. I was reading my text, when I came across the 10% rule, which says, "On average, only about 10% of the energy of any trophic level is passed on to the next trophic level." Since humans are omnivorous, we have the option of eating plants, animals, or both. People on the atkins diet take the role of a secondary consumer, while vegetarians take the role of a primary consumer, and people on the food pyramid diet take the role of both. Does this mean that a vegetarian will have more energy than someone on the atkins diet? Will the atkins diet cause people to become lethargic when compared to people on the food pyra…

Hey Everyone, Does cigerette smoking add to global warming or air pollution? And if so, can some scientifically explain in easy terms how this process occurs?

In this forum there have been threads about self-regulation of plant population and getting NPK fertilizer out of the ocean---basically concern is how the human population can regulate itself (short of war, famine, natural disaster, plague etc.) people are looking for ideas that can give them hope that things will work out the NPK thread was basically asking HOW WILL WE HAVE ENOUGH TO EAT WHEN THE OIL RUNS OUT? and the oceans are overfished and the human population is 9 billion (which it might stabilize at) and more of the soil is exhausted etc. So what ideas do you have? Let's say that with voluntary birthcontrol the current projection of world pop st…

Ok, so its not quite ectoplasm, but its really weird. I live in south east London in the UK, in a vaguely surburban area and on a steep hill. There's a very strange phenomenon occurring outside my house, all my neighbours, family and friends have commented on it, yet no one has any answers. Maybe someone on this site can help... A couple of months ago an ‘ectoplasm’ - thick, viscous jelly-like yet clear slime started to ooze up from between the pavement cracks. It occurs in about 6 or 7 places over an area of about 8 square metres. Each patch of slime is between 3cm and 10cm in diameter. Even after heavy rain has washed the majority of it away, it soon returns. …

This is a theory suggested by Peon on IRC, which was widely ridiculed. He said to post it here, so here goes. According to Peon, imprinting (such as imprinting to a mother) is controlled by genetics. The genes control what is imprinted into and what is not, and when this happens. A summary of his argument: Peon thinks that DNA is the root of imprinting, while the rest of the people on the channel believed it was not, but instead a result of memories and neurological functions (although these functions are also indirectly controlled by genetics, imprinting is not directly controlled, at least according to the rest of us). Opinions?

Hey, its my first post and I just wanted to see if I could get some recommendations for excellent books on either Climatology, Atmospheric Science, or Oceanography. My purpose is not for school but for self learning reasons. Something that is not so specialized but rather broad. Thanks very much!

hi i need a help in this experiment the question is which plant species would be a useful indicator speciesfor acid rain pollution

2 years ago I started with a single barley seed, that developed 6 ears and each had roughly 40 seeds per ear (a 1:240) ratio. I planted them all again early this year and now have just over 2kgs of seeds, now at the 1:240 ratio that`s roughly 57,600 seeds in 2 years from a single one! I plan on do the same next year and calculate over 13 million seeds in 3 years! that adds up to about 553kgs and a whole lot of land being taken over. I find that quite an impressive feat by good old mother nature, but what`s really "scary" is the Pumpkin! a single plant will grow at least 10 pumpkins, and each pumpkin will have nearly 2000 seeds in it, so from 1 seed in one season you …

Hey, I'm writing a story, and I'm wondering what the affects of a very arid climate would be on a humans appearence (oily hair, not oily hair, skin, that sort of thing)

My back yard has a horrible mosquito problem. Under close analysis, I have identified them as Asian Tiger Mosquitos (Aedes albopictus). There is no standing water that I can find anywhere near the yard. There is no place that I can find for the mosquitos to lay their eggs. The nearest possible location is a drainage ditch several city blocks away, and it seems strange that the mosquitos would fly so far from their breeding ground to be in my yard, while the houses immediatly next to the ditch do not have problems with mosquitos. Stranger than that, is that the yards immediately adjacent to my back yard do not have mosquitos. While trying to figure out why they ar…

What is the world going to do when we run out of land to develop? We can't artificially make land! Even if that was done, we would eventually lose the oceans, and die of Oxygen loss. Where can we live when the world reaches its limits and we lose our elbow room? The single family homes will be replaced with towering skyscrapers to house all of the newly needed families. Eventually, we will exhaust all of our natural resources, meaning no more plastic, no more new cars, no more houses, buisness, maybe energy, what else could we lose? What can we do about it?

Is ther anything called enviromental science? The word enviromental I understand I also equate/relate the word science as study/knowledge. I am more interested in this oplanet as a whole inside and out than space are quantum physics. Does anyone know of sub disciplines in enviromental science? pljames

this subforum is concerned, among other things, with the human population and its impact on the global environment (thus indirectly on the ecology and habitats of wild species) should ECONOMICS be split off from this as a separate topic, or should it be integrated into this mix? what do you think? Economics is a really important science and there is no specific spot for it in the SFN menu. If you isolate it from biology or compartmentalize it, say, with politics, what kind of thinking does this encourage? The way I look at it, Economics is one of the major factors that determine the growth of human populations and the kinds of impacts they have on the env…
