Carbon Dioxide is the most well known among these green house gasses that the term is almost used interchangeably with green house gasses itself. Carbon Dioxide is the gas that we give out every time we breathe. But there are other human processes that produce Carbon Dioxide. These include the use of chemicals, production of cement, iron or steel, burning of oil, coal, and other natural gasses and during waste combustion.

Nitrous Oxide emission happened during industrial and agricultural activities. It is also emitted during burning of fossil fuels and solid waste. It is also possible that Nitrous Oxide is emitted from biological waste mixed with waste water and when the biological waste of livestock is transformed into usable manure. The emission of Nitrous Oxide in the atmosphere is not in great abundance but has a devastating impact on the environment.

Methane emission is seen greatly when the amount of waste increases. Methane is also released during decomposition of organic waste, whether in landfills or in livestock farming and during mining processes.

Human activities add to the abundant level of naturally occurring green house gasses in the environment.

Wash your hands thoroughly and often. It’s the best way to prevent infectious diseases. You can’t overemphasize this simple reminder. By frequently washing your hands, you wash away germs that you have picked from other people, or from contaminated surfaces, animals and waste. One of the most common ways people catch colds is by rubbing their nose or eyes after their hands have been contaminated with the cold virus. Before you know it, everyone around you is getting sick.

The important thing to remember is that in addition to colds, some serious diseases, like hepatitis A, meningitis, infectious diarrhea and SARS, can be prevented of we make a habit of washing hands.

When should you wash your hands? Before, during and after you prepare food, before and after you eat; after you use the bathroom; after handling animals or their waste; when your hands are dirty; and more frequently if some one in your home is sick. It is estimated that 1 out of 3 people do not wash their hands after using the restroom. So their tips are also important when you’re out in public.

Wash your hands with soap for 10-15 seconds or about the length of a little tune.

Routinely clean disinfect surfaces. Cleaning and disinfecting is not the same thing. In most cases, cleaning with soap and water is adequate. It removes dirt and most germs. However, in other situations, disinfecting provides and extra mile of safety.

You should disinfect areas where there are both high concentrations dangerous germs and a possibility that they will be spread to others. Given the right conditions, some germs can be live on surfaces for hours and even days.

The “hot zones” or contaminated areas in your home are mainly the kitchen and bathroom.

All food may contain some natural bacteria, and improper handling gives the bacteria a chance to grow. Also food can be contaminated with bacteria from other sources that can make you ill. Unclean food can cause fever, stomach cramps, vomiting and diarrhea.

If you are cleaning up body fluids such as blood, vomit or feces, you should wear rubber gloves, particularly if you have cuts and scratches on hands.
