Causes of Waste in a Society:

A material or substance is considered to be a waste if when they are no longer useful or purposeful; and are thus discarded.

In some societies, we see waste materials all around. Apart from the fact that these waste are unpleasant to the eyes, they will also negatively affect national growth and development. In addition, inappropriately disposed wastes will promote the spread of diseases and (deaths) in areas where they are present.

Please read on the Effects of Improper Waste Management here.

Below are some of the causes of increasing wastes in various societies:


1. Overpopulation

The larger the number of people in a society, the increase in the amount of waste produced.

Overpopulation will directly affect the increased turnout of waste materials from homes, market places and industries.

Note: Waste generated by the populace can be put into various types.

Please read more on Types of Waste (and Introduction to Waste Management) here.

 

2. Corruption

When funds allocated to waste management are siphoned, the society and its inhabitants will suffer. This is one of the many reasons for the presence of landfill waste in a society.

Corruption is a disease that eats up the society, either directly or indirectly.

Please read on the Functions of Government here.

In some cases, trucks meant to evacuate wastes from residential areas fail to show up because they are yet to be paid by the government for a previously done job.

The above instance results in the accumulation of wastes within these environments.

 

3. Lack of Waste Management Education and Awareness

Education is always considered as the key to every successful society.

Oftentimes, market places and even residential environments are seen to be littered with various waste materials. If the residents were properly educated on the inappropriateness and dangers of their actions, the dumping of waste in these streets (and market places) will be reduced.

Note: The power of education should never be underestimated in all facets of life.

Educating and creating awareness to the citizens of a country will go a long way in reducing waste in the affected neighborhoods.

Please read on the Consequences and Solutions to Illiteracy here.

 

4. Advancement in Technology

When a nation advances in technology, there will be a corresponding increase in the production of non-biodegradable waste like metal chips, rubbers and plastics.

Please read on the Internet of Things here.

Non-biodegradable wastes cannot be broken down and hence will always persist in landfills as solid waste.

 

5. Laziness

Some people would rather discard their household waste just anywhere because they are too lazy to go to an appropriate waste dump site, perhaps because of distance.

Please read on Values here.

 

6. Avoidance of Waste Disposal Fees

Certain residents would rather litter the environment with various kinds of waste because they intend to avoid the payment of waste disposal fee (at waste disposal and management sites).

Please read more on Reputation here.

 

7. Lack of Recycling Industries

The presence of a few recycling industries in a society will result in the accumulation of excess waste.

When waste materials are properly recycled, new products will become cheaper since the cost of production becomes reduced from these recycled wastes. (That is, waste materials becomes raw materials for various production industries).

It is the function of production industries to pick up necessary waste materials and recycle them into new products through production.

Please read more on Production here.

 

8. Absence of appropriate Fines and Punishment to Offenders

When the people living in a society constantly dump waste materials anywhere; and without any form of fine or punishment; the act of improper waste disposal will be encouraged.

Personally, I feel bad each time I see people dump waste materials like the sachet, plastics, seeds and back of fruits (before or after they are consumed).

They consciously (or unconsciously) dump these wastes on the streets and major roads without any thought on the impending harmful effect of such waste.

Please read on the Responsibilities, Duties and Obligations of Citizens here.

Using the city of Lagos as an instance, a government agency named KAI (Kick Against Indiscipline) was previously establish to penalize and arrest offenders (that dispose waste inappropriately alongside other crimes) within the Lagos Metropolis. During this period, I discovered that city of Lagos became cleaner because most people adhered to the agency's rule while the culprits were indeed penalized.

Presently, it appears that KAI functions no longer in Lagos State. The has made some people go back to this unhealthy act.

Amazing facts in Basic Science

Cranberries - Len Academy

Ripe cranberries will bounce like a ball. For this reason, they are nicknamed 'bounceberries'. They will also float in water

Tomatoes and Avocados are fruits, not vegetables

Sweat in itself doesn't smell. The smell that accompanies sweat is actually caused by the presence of bacteria on your skin. This bacteria breaks the sweat coming out of your sweat pores down into acids, thus making it smell.

Deodorants contains alcohol and are antibacterial. They work by killing the bacteria that makes sweat smell

Chewing aspirin during a heart attack may be a life saver. This is true because the drug inhibits platelets from forming a clot that can block an artery of the heart, thus stopping a heart attack

The kneecaps of newly born babies are not made of bone. Rather, they are little bits of cartilage which ossifies (turns from cartilages to bone) from age 2 to 6

Ice cubes - Len Academy

Ice cubes made with fresh water are white in color while those made with boiled water are crystal clear

Cats are unable to taste sweet things

Apples float on water. Other fruits that float on water include lemons, bananas, pears, and oranges

Rain water is said to be pure because it's colorless, odourless and tasteless. Interestingly, it also contains vitamin B12.

Vitamin B12 is an important nutrient that keeps the blood cells and neurones healthy. It also assist in building the DNA (a genetic material present in the cell's nucleus). Vitamin B12 also aid in the prevention of megaloblastic anemia which makes people weak and tired

Rasceta is the name given to the lines on your palm


NOTABLE POINTS IN Basic Science

Waste Management can be defined as the process of collecting, processing, recycling and controlling any material considered as waste.

Improperly disposed waste litters on road sides, in land fills, gutters and ditches. They are generally bad for the following reasons:

Wastes can be classified into various types. These are:

  • Biodegradable waste

  • Non-Biodegradable waste

  • Refuse

  • Sewage

  • Recyclable waste

  • Electronic waste

  • Green waste

  • Biomedical waste

  • Metabolic waste

  • Radioactive waste

  • Chemical waste

  • Animal product waste

Disaccharides are composed of two monosaccharides joined together; thus are also referred to as double sugars.

Disaccharides are often added as sweeteners to food; for instance, the table sugar called sucrose is a disaccharide often used by us to sweeten our tea.

Maltose is another disaccharide used as an ingredient for making malt drinks, chocolates and candies.

The breast milk contains the disaccharide -> lactose.

Lactose is very vital for the normal growth and development of infants.

In adults, disaccharides are non essential nutrients. This implies that we can live without them as adults.

Below is a summary of monosaccharides that make up disaccharides (double sugars).

  • Maltose = Glucose + Glucose

  • Lactose = Glucose + Galactose

  • Sucrose = Glucose + Fructose

Other examples of disaccharides include trehalulose and isomaltulose

Polysaccharides are complex sugars. These are what we often eat whenever we eat carbohydrates.

We have four types of polysaccharides namely:

  1. Starch

  2. Glycogen

  3. Chitin

  4. Cellulose

Starchy foods include rice, cassava and yam.

Glycogen is stored in the human liver; as a result of the joining of many glucose molecules.

Chitin is a major component of insect and anthropod's skeleton.

Cellulose is a major component of a plant's cell wall. They cannot be digested when eaten by humans; hence they function as roughages.

Roughages are not classified as one the classes of food in humans. This is due to the fact that they aren't digested. They will rather facilitate the movement of bowels in the large intestine (colon). For this reason, they can be very useful in treating constipation.
