Effects of Improper Waste Management:

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

Wastes are generated from homes, factories, market places, hospitals, schools, industries and many other places. The growth and development of Nations where these wastes are prevalent will be adversely affected.

Please read on the Causes of Wastes in a Society here.

Below are some of the effects of improper waste management:

1. Atmospheric Pollution

The burning of waste materials like plastics, papers and rubber will contaminate the atmosphere with gases like carbon(II)oxide, carbon(IV)oxide and sulphur(IV)oxide.

Atmospheric pollution via the release of toxic gases will also result from biodegradable waste (which are eventually broken down or decomposed by bacteria and fungi).

Please read on the Types of Wastes here.

Also, waste may contain toxic chemicals like dioxin (produced from the rearing of broilers).

The pollution of the atmosphere as a result of these waste will negatively affect humans, plants, wildlife and other living organisms.

Please read more on Air Pollution, it's Effects and Solutions here.


2. Death of Aquatic Organisms

The pollution of water bodies by solid and liquid waste will result in the suffocation and death of aquatic organisms.

As an instance, oil spillage has been a major problem in the riverine areas (South-South region) of Nigeria.

Note: Crude oil or petroleum is a natural resource present in the South-South states of Nigeria.

Please read on the Fractional Distillation of Petroleum here.


3. Climate Change and Green House Effect

The decomposition of biodegradable waste will result into the release of green house gases like carbon dioxide, methane and nitrous oxide into the atmosphere.

In addition, human activities like combustion and burning are constantly releasing more greenhouse gases especially through the release of carbon(IV)oxide into the atmosphere.

Please read more on Greenhouse gases (through the Functions of the Atmosphere) here.

Excessive greenhouse gases have an adverse effect on weather conditions over a long period of time. This is so because these gases are gradually bringing about an increase in the temperature of the earth, giving rise to global warming.


4. Contamination of the Soil

Certain waste materials such as plastic containers, ink, oil and petroleum products will have damaging effects on the soil.

The aformentioned waste materials will adversely affect the growth of plants and other organisms living in and on the soil. As a result, the soil becomes less fertile and agricutural land and its activities becomes negativity affected.

Please read on Agricultural Land and Uses of Land here.


5. Reduced Atmospheric Oxygen and Increased Atmospheric Carbon(IV)oxide

With regards to the carbon cycle, plants are the only organisms that take away carbon(IV)oxide from the atmosphere. They do this through a process termed Photosynthesis.

Plants are also the only organisms that fixes oxygen back into the atmosphere. They do this through photosynthesis.

Please read on Photosynthesis here.

Note: Without atmospheric oxygen (generated by plants), humans and animals will cease to exist.

Please read on the Characteristics of Living Organisms here.


6. Increase in the amount of Carcinogens

Carcinogens are substances that can cause cancer.

Radioactive wastes can be potentially damaging to humans when inhaled. They increase the formation of cancerous cells the human systems. Some may even cause leukemia, a form of blood cancer.

Please read on the Classification Bones (to understand how Blood Cells are produced).


7. Flooding and Blockage of Drainages

When excess waste materials find their way into gutters and pipes, blockage of such gutters and pipes will result.

Blocked gutters and drainages bring about flooding in the affected areas.

Please read on Soil Erosion here.

Also, stagnant waters will act as breeding sites for mosquitoes.

Please read on Vectors of Diseases here.


8. Diseases

Wastes materials found in neighborhoods serve as homes to pest and pathogens. These pathogens will in turn cause diseases in the long run.

Please read on Micro Organisms causing Food, Air and Water borne Diseases here.

As an instance, Lasa Fever is a disease caused by pathogens carried by rodents dwelling in dirty environments.

Other diseases caused as a result of improper waste management includes cholera, malaria, fever, dysentery, diarrhea and tetanus.

Amazing facts in Basic Science

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 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 🍎 actually float on water. Other fruits that float on water include 🍋 lemons, 🍌 bananas, 🍐 pears, and 🍊 oranges

Rain water 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 ✋

Goats have rectangular pupils in their eyes.

Think of the pupil as a hole located in the centre of the iris within of the eye.

Note: To get an idea of an iris; 'when one is said to have blue eyes', it's because the iris is blue

Among all land animals, 🐘 Elephants 🐘 have the longest gestation period.

They stay pregnant for 22 months before giving birth to their young


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); and for this reason, they can be very useful in treating constipation.
