The question has been answered.  The bigger question is how to prevent.  And, a couple of MD's found and easy solution, but you have to do it religiously.\n\n4 ounces of fresh lemon juice in 2 liters of water.  This is what you have to drink every day for the rest of your life.  If you have chronic stones developing.\n\nThere is chemical in the juice which breaks down the stone slowly and will prevent it from forming.  Most of us have a similar chemical in our bodies, so we don't develop stones.  The unlucky people who genetically don't or don't produce enough develop stones.

There are lots of ways. Buy things that will loast for a long time (glass plates versus paper). Build a compost heap in your garden, grow your own plants, recycle the things you throw away, turn off the lights when you leave a room, air dry your clothing rather than putting it in the dryer, wash you dishes by hand, bathe less often and ue a wood burning stove.

Soil conservation refers to techniques used to prevent soil being lost or harmed by overuse, erosion, salinization etc.\n\nTechniques recommended by the U.S. Natural Resources Conservation Service include:\n\nwindbreaks \nterracing \ncover crops \ncontour plowing \n\nfor more details, visit http://en.wikipedia.org/wiki/Soil_conservation\n\nhttp://en.wikipedia.org/wiki/Water_conservation

Create a little clear area, dig a hole in the ground then fill it with sand. Make a little wood border to hold the sand in (only for the back, left, and right side though, you need the front to be open)then stick a long metal pole into the sand and ground to it can hold steady when being hit with the shoes. Have fun!

Their are various ways.  One way where i live is by putting large nets to cover the area.  This holds the rocks in place.

Water, wind and ice can all cause erosion in rocks.  Wind will often blow small bits of sand or pebbles at a rock, which can wear it down.\nWater does something similar, slowly wearing down a rock over time.  This is why you often find round stones in and around rivers.\nWater also gets into the cracks of a rock.  As the water freezes, it expands and causes bits of the rock to break off.

Don't use sand! I believe that they use crushed up walnut shells in blasting on surfaces that you don't want to get all pitted up.

There was just a landslide that buried a school. Erosion needs to be prevented.

make more ozone. jk the best way to prevent it is to not cut down as many trees, not use cfc's (clorofloracarbons), and cut down on major pollution, such as factories and cars like hummers

Set up your backpack back on a picnic table or surface that is above your knees. Loosen arm straps.  Insert child. Put one arm through strap and then lift pack off table and put through other arm in one motion. This will eliminate a lift and twist from ground level that could tweak your back. Snug up straps. Reach back and "close" kickstand.  Do the reverse for removal.  Always have a hand on the backpack when putting on or taking off to eliminate tipping.  Most backs have a handle of some sort on the top of the pack.  The first time you try this have someone close by.  After a while you will be a pro.  Have a good hike!

Screen savers help but i WOULD RECOMMEND antireflective coated lenses. Also get up and get away from the monster for breaks.  Better light  works the best.

You want to use either water or a VERY mild cleaning solution - nothing abrasive.  Use a clean, non-shedding cloth (like an old, soft t-shirt), and clean the radii of the circle (meaning wipe from center to edge or vice-versa - not across the CD); just a straight line from center out to edge.
