It it true?

Question

Is it true that all the factory and ther cars give tow too many polution and people cut down trees but to not plant new ones and people found a hole in the atmosphere and every year it get bigger and then the air gets out and then the earth its going to blow up! becouse everyone says that!

Answer 1

No reason to panic, but, yes, that is sort of true. But not the part about the earth blowing up. There are problems and they will take time to fix, but we can do it if we try. Read some of the facts about it here:

Answer 2

No, no and no. Firstly, the earth is not contained in a bag of air, like a big balloon, that will explode if it gets a hole in it and all the air will rush out. That's not the way the atmosphere works. The air in the upper stratosphere is very, very thin. As you get closer to earth, the air becomes thicker, from the weight of the air pressing down from above, until you get down to sea level, where the air is thickest of all. It's much the same with the ocean - the density of the water is less at the surface but as you go deeper, it becomes more and more dense.
The 'hole' in the atmosphere means merely a gap in the protective layer that screens out ultraviolet rays.
Factories and cars do contribute to air polution, but people are becoming more aware of this problem and steps are being taken to improve the situation.
Trees are cut down, but tree planting is a big industry and many millions of new trees are planted every year.

Finally, the earth is not going to blow up. I don't know who has been telling you this, but you can tell them that they are wrong. Absolutely, incontrovertbly and indubitably wrong. And tell them I said so.

Answer 3

To take one question at a time - every time you burn something, energy is released as the old, old chemical bonds in the fuel are broken and re-formed to include oxygen atoms. You end up with oxygen combinations with carbon, nitrogen and sulfur that are released as gas and are considered pollutants. Factories, cars, trucks, furnaces in houses, electric-generating plants, lawnmowers, and so forth, all produce some amount of pollutants. If those gases were good for something, then they wouldn't be pollutants, but unfortunately, some act as poisons in high concentrations or serve to trap heat like the glass windows of a greenhouse. A little bit isn't a problem; too much is a big problem.
Now trees - trees, like all plants, use a lot of carbon to build their bodies. The carbon is used to make long strings of a tough molecule called cellulose that the plants use to make their stems, leaves and bark. Trees especially use a lot of carbon, and if there were as many trees around as there used to be, it might help to take carbon dioxide out of the atmosphere and store it away.
The 'hole in tha atmosphere': High up at the outer edges of the atmosphere is an area where high-energy ultra-violet light from the sun hits Oxygen atoms. Normally Oxygen is found in pairs, but when it's hit by a lot of energy, it can form a 3-oxygen molecule called Ozone. This isn't real stable, so it breaks down pretty easily back to regular O2, then absorbs some more of the ultra-violet light energy and goes back to O3 and so forth. Back and forth, and each time it takes up some of the high-energy UV light and then releases that energy later in a less harmful (to us) form. That's the 'ozone layer' of the atmosphere, and by absorbing a lot of that high-energy UV light, it keeps it from getting down to our level and hitting us directly, damaging us and other delicate things. Unfortunately, if something prevents the oxygen from going from O2 to O3, no ozone gets made and the UV light just zips on through to blast us and every other living thing down here on the surface. Certain chemicals used in spray cans and in older refrigerators and air conditioners can keep ozone from being formed. They're not supposed to be used any more, but there's still a lot of them around, and they still have an effect. The 'ozone hole' over the Antarctic is worrisome, but it seems to have stopped getting bigger, and may be starting to shrink again. Air doesn't escape through the 'hole' - it just lets UV light in. None of these things could cause the Earth to blow up, anyway, although they all have bad effects on how we and everything else on this planet will live.

Answer 4

Well. The earth won't blow up anytime soon, but I suggest you read the following:

http://en.wikipedia.com/wiki/ozone_hole

And, yes, the cars pollute immensely, that's why people are trying to mass-market electric cars, they can help save the environment:

And, all of the paper you use comes from trees that have been cut down. Also, the Amazon Rainforest is being cut down at a rate of 1 acre per second (an area the size of New Jersey is chopped down each year):

50 years ago, the carbon concentration in the atmosphere was 280 ppm, now it is 380 ppm. It should be going down, but only about 1 ppm over 500,000 or 1 million years. So, yes, to answer your questions, humans have had a horrible effect on the environment.

And, no, the atmosphere does not get bigger, more carbon gets stored in it, but gases are flexible.

Answer 5

The hole in the ozone layer is actually starting to heal. And air does not escape through it, that's not how it works. The ozone layer pretty much has one function: blocking ultraviolet radiation. No particulate matter can "escape" through a hole in the ozone layer.

Answer 6

yes, most of that is true, except for the air escaping and the world blowing up, i don't think that's going to happen.

ps. it's called global warming

Answer 7

Are you high right now?

Answer 8

i think it is true
