Causes of waste in a society:

A material or substance is considered to be a waste 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.

Meanwhile, understand that waste generated by the populace can be generally put into various types.

Please read more on types of waste here.


2. Corruption

When funds allocated to waste management are siphoned, the society and its inhabitants will suffer. In this regard, corruption is a disease that eats up the society, either directly or indirectly. This is one of the many reasons for the presence of landfill waste in a society.

You can read on the functions of government here.

As a result of corruption, 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.

In some societies, 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 become reduced.

It is worthy of note to state that the power of education should never be underestimated in all facets of life. The education and creation of 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.

You can read on the internet of things here.

Non-biodegradable wastes cannot be broken down in our lifetime; 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 dump site, perhaps because of distance. This is a sad reality and I have seen people who exhibit this poor behavior.

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.

Interestingly, when waste materials are properly recycled, new products will become cheaper since the cost of production becomes reduced from these recycled wastes. As a result, waste materials become 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 the processes of 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 sachets, plastics, nylons and banana peels on the streets and roadsides. 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 'Kick Against Indiscipline (KAI)' 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

Of all animals, mosquitoes hold the record of killing most humans annually. They are responsible for the deaths of 725,000 - 1,000,000 persons yearly

Antibiotics fights and kills bacteria. However, they do nothing to a virus

All insects have six legs. However, dragonfly has six legs but can't walk

The chin is defined as the protruding part of the face below the mouth, formed by the apex of the lower lip. It is shown below:

Chin - Len Academy

Interestingly, humans are the only animals with chin

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


Matter is composed of particles which can be:

  1. Tightly packed together (as seen in solids).

  2. Loosely packed together (as seen in liquids).

  3. Completely separated (as seen in gases).

The movement of the particles of matter is a function of the overall kinetic energy present in them. You can think of kinetic energy as energy in motion.

An increase in the particles' vibrational, rotational or translational motion will imply an increase in temperature while a decrease in the particles motion (vibrational, rotational and translational) will mean a decrease in temperature. Based on this knowledge, we can therefore define temperature as the measure of the average kinetic energy possessed by the particles of matter.

Intelligence Quotient (IQ) is a score derived from a set of standardized tests developed to measure a person's cognitive abilities in relation to their age group.

IQ may also be defined as the ratio of mental age (MA) to chronological age (CA) multiplied by 100.

Below are some formulas pertaining Intelligence Quotient:

  • IQ = MA x 100 ÷ CA

  • MA = Mental age

  • CA = Chronological age

  • IQ above 100 = Brilliance

  • IQ that equals 100 = Average

  • IQ below 100 = Below Average

Human Brain Gyri and Sulci - Len Academy

Among all organisms in the universe, the human brain is the most developed. This highly developed brain present in humans is the biggest factor that makes them unique from every other organism on earth.

According to research, the more folds a brain has, the more intelligent the organism possessing it will become. To this end, humans have brains with the greatest number of folds (or bumps) called gyri and grooves (or indentations) called sulci.

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
