Fiber is a plant substance that is not found in animals. Fibrous substances are vital for the human body andthe digestive tract. Fiber also aids in the prevention of many illnesses. Here's the scoop on the benefits of fiber

and how much you should need.

1. Indigestion and ConstipationThe most important use of fiber is in digesting food. Fibrous substances add considerable bulk to yourstool. It helps your stool become big and soft, thus making it easier to pass through the intestinal tract.Eating fiber rich foods can help cure constipation, thereby helping to avoid many other serious healthconditions that can often develop as a result of this uncomfortable situation.

2. Heart AilmentsFoods that contain soluble fiber, such as barley, beans, and lentils have a good effect on cholesterol levelsand normal functioning of the heart. Citrus fruits have similar effects on the human system.

3. CancerMedical experts suggest that fibrous food helps in protecting against colon cancer, breast cancer, andovarian cancer. Significant research is still ongoing to confirm these findings.

4. DiabetesNormalized blood sugar levels are essential for reducing the risk of diabetes. Diabetic people have foundsubsequent reductions in their glucose levels due to intake of fiber-rich foods.

5. ObesityHigh fiber foods are more bulky than other food items. Taken under a dietary experts guidance, fibrousfoods give the feeling of a full stomach and curb the urge to eat more. This helps people who would like toreduce their weight and control their eating habits without becoming hungry.

6. ToxinsFiber speeds up the passing of food through the intestinal tract, thus preventing constipation ordiverticulosis disorders. Toxic waste materials are also easily flushed out of the system through soft andeasy stools.

Women usually need 25 to 30 grams of fiber on a daily basis, whereas men generally need 30 to 40 grams offiber intake every day. Therefore, make sure you have your fill of high-fiber foods that will help you maintaingood health.

Staying health and safe at work is important. No matter what your job, its important to reduce your risks of

injury and ilness at work. Here are some tips to help make yout workplace safe.

1. Understand the risks.Once you know the particular hazards of yourjob or workplace, you can take steps to reduceyour risk of work related injury or ilness.

2. Reduce workplace stress.Common cause include long hours, heavyworkload, job insecurity and conflicts withcoworkers or bosses. Stress can lead todepression, sleeping difficulities and problemwith concentration.

3. Take regular breaks.Staying fresh and alert will help you avoidinjury or burnout. Schedule the most difficulttasks of each day for times when yourconcentration is best, such as first thing in themorning.

4. Avoid stooping or twisting.Use ergonomically designed furniture andequipment, and rearrange your work area sothat everything you need is within easy reach.

5. Use mechanical aids wheneverpossible.Instead of trying to lift or carry a heavy object,use a wheelbarrow, conveyor belt, crane orforklift.

6. Protect your back.If you do need to pick up and carry heavyloads, keep the load close to yout body andlift with your thigh muscles.

7. Wear protective equipment to suit thetask.If worn correctly, gear such as earplugs,earmuffs, hard hat, safety goggles, glovesor full face mask can dramatically reduce

your risk of injury.

8. Stay sober.Alcohol and drugs are a contributing factorin around three percent of workplacefatalities.

9. Talk over any concern.Your employer or human resourcesmanagers need to be informed abouthazards and risk. Your employer is legallyobliged to ensure a safe workingenvironment.

10. Know your right.Organizations or unions can offerinformation and advice on workplace safetyissues.

The ozone layer is an invisible layer of protection around the planet that protects us from the suns harmful

rays. Depletion of the crucial ozone layer of the atmhosphere is attributed to pollution caused by chlorine andbromide found in Chloro-floro carnons (CFCs). Once the toxic gases reach the upper atmposphere, they

cause a hole in the ozone layer, the biggest of which is above the Antartric. The CFCs are banned in many

industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from

reaching the earth.

The ozone depletion process begins when CFCs and other ozone-depleting substances (ODS) are emitted

into the atmosphere (1). Winds efficiently mix the troposphere and evenly distribute the gases. CFCs are

extremely stable, and they do not dissolve in rain. After a period of several years, ODS molecules reach

the stratosphere, about 10 kilometers above the Earth's surface (2).

Strong UV light breaks apart the ODS

molecule. CFCs, HCFCs, carbon

tetrachloride, methyl chloroform, and other

gases release chlorine atoms,

and halons and methyl bromide release

bromine atoms (3). It is these atoms that

actually destroy ozone, not the intact ODS

molecule. It is estimated that one chlorine

atom can destroy over 100,000 ozone

molecules before it is removed from the

stratosphere (4).

Ozone is constantly produced and destroyed

in a natural cycle, as shown in the above

picture, courtesy of NASA GSFC. However,

the overall amount of ozone is essentially

stable. This balance can be thought of as a

stream's depth at a particular location. Although individual water molecules are moving past the observer, the

total depeth remains constant. Similarly, while ozone production and destruction are balanced, ozone levels

remain stable. This was the situation until the past several decades.

Large increases in stratospheric chlorine and bromine, however, have upset that balance. In effect, they have

added a siphon downstream, removing ozone faster than natural ozone creation reactions can keep up.

Therefore, ozone levels fall.

Since ozone filters out harmful UVB radiation, less ozone means higher UVB levels at the surface. The more

the depletion, the larger the increase in incoming UVB. UVB has been linked to skin cancer, cataracts,

damage to materials like plastics, and harm to certain crops and marine organisms. Although some UVB

reaches the surface even without ozone depletion, its harmful effects will increase as a result of this problem.
