Ozone Layer

Not likely. We are experiencing some reduced crops, some loss of arable land...

If the world is ending, it is because we are overbreeding, setting ourselves up for famine and pestilence. So far, Science has moved just fast enough to save us.

Trees, not only absorb carbon dioxide, provide shade, prevent erosion, but they can also help muffle noise. Think of trees as big, leafy, air-purifying, oxygen-producing, white noise machines. Acting as shields, trees reduce the intensity of the sound waves considerably and it is the sound produced by the wind passing through the leaves that really helps muffle noise. A properly-designed buffer of trees and shrubs can reduce noise by about five to ten decibels-or about 50 percent as perceived by the human ear, according to the USDA National Agroforestry Center. For maximum effect, experts suggest planting a variety of both hedges or shrubs and taller trees to create a wall of foliage from the ground up. Such examples as cottonwoods, poplar and aspen trees are especially good at noise reduction because their leaf-shapes produce a good, strong rustling sound.

We are just now beginning to suffer the effects of wanton dumping of "non-ozone friendly" products into the environment, plus whatever Nature decided to do to us on Her own. The decisions we make now regarding the ozone layer, will affect how many of our children get to live on this planet. Personal decisions on a single product will amount to nothing. Decisions to provide only good choices will make the only meaningful difference.

No, not a source. Cell phones are a product of fossil fuels, that is, they are made from plastic (as well as many other things, like metals).

well there are a lot of reasons that we cause golbal warming. The main one I can think of is every time that you plug something in. I believe that global warming is not being caused by humans. There are just as many scientist saying that it is not happening than there are saying that it is.

It protects the mine because it could take away harmful ores, it can start new homes of animals or organism's, and it can also improve land value by putting it back together.

pesticides sprayed on the soil later evaporate and rise up and damage the protective ozone layer so eventually harmful rays from the sun reach the earth. :)

Canon's A-series cameras were (and are) prone to developing a noisy squeal when the shutter is fired. The problem occurs when the lubrication on the mechanism dries out over time. The fix is to relubricate the offending parts. While there are instructions (available online; do a search) for doing this yourself, you can create worse problems if you get oil or grease where it doesn't belong. I've had cameras with the problem, but I chose to have a professional CLA (clean, lube, adjust) done to the camera.

I have an ae-1, The shutter speed is the dial on the top right side with all the numbers and the word "program" on it. Program is idiot-mode: used just to snap shots. In bright daylight use higher speed like 1000 or 1600 and in darker situations use like like 100. anything under 60 requires a tripod, for a clear picture. The speed can be so slow, that camera will allow you to set the speed slow enough that it could take a full minute to take a picture.

The main sources of thinning of the ozone layer are chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances, which are released through human activities like industrial processes, aerosol sprays, and refrigerants. These substances break down ozone molecules in the stratosphere, leading to a reduction in the ozone concentration. Additionally, natural processes like volcanic eruptions and solar flares can also contribute to ozone depletion.

The main cause of thinning is CFC's. Global warming also affects it.

Although the production and release of CFCs have significantly decreased due to the Montreal Protocol, a global agreement to protect the ozone layer, they can remain in the atmosphere for many years. The impact of CFCs on the ozone layer is still observed, but it is gradually decreasing. Efforts to phase out CFCs and switch to ozone-friendly alternatives have been successful in mitigating their effects.

Man can stop the destruction of ozone layer by his efforts too. All we have to do is to stop the usage of ozone depleting products which cause ozone depletion.
