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

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

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

🦘 Kangaroos 🦘 can't walk backwards

The 🥛 milk 🥛 of an 🦛 hippopotamus 🦛 is pink in color

The seed of all fruits are present on the inside with the exception of one.

That exception is 🍓 strawberry 🍓

🍓 strawberry 🍓 has it's seed outside the fruit

It actually takes 🍍 pineapples 🍍 2 years to grow

NOTABLE POINTS IN Basic Science

The eyebrow is an area of dense, delicate hair just above the eye.

Eyebrows perform two main functions:

  1. Protects our eyes against sweat, rain, dirt and other atmospheric contaminants.
  2. It helps us express our emotions.

Eye Brow - Len Academy

Eyebrow modified in the form of Nike logo.

Note: Eyebrows can also be modified to enhance beauty.

All fruits have seeds.

There is nothing like a naturally occurring seedless fruit. Even banana, coconut and pineapple have all got seeds.

Weight can be defined as the force of gravity acting on an object.

If you traveled to space, you would be weightless because there isn't any force of gravity acting there. We all have weight on earth becasue the force of gravity acts here.

Weight is measured in Newton

Please read on the concept of Mass and Weight here

Mass is the amount or quantity of matter (substance) contained in a body. For instance, everything you are composed of, both from within and outside will make up your mass.

Mass is constant throughout the universe. You will have the same mass on earth and moon respectively.

Mass is measured in gram or kilogram and it's quite different from weight.

Matter is anything that has mass and occupy space.

Matter can exist in four states namely:

  • Solid
  • Liquid
  • Gas
  • Plasma
