CLIMATE CHANGE

As an emerging issue, climate change mostly triggered by human activities is presumed to have far reaching impact on human beings and environment as a whole. Climate change refers to the alteration in statistical distribution of weather patterns, usually 25-30 years.
The climate is changing as a repercussion of industrial gases released into the atmosphere. The gases allow sun’s radiation to reach to the earth’s surface but these gases trap the heat reflected into the atmosphere. The heat tends to increase around the earth, global warming as an outcome of trapped heat is called global warming. Green house gases in the atmosphere act like a mirror: reflecting back to earth part of heat radiation, which would otherwise be lost to the space.
The causes of global warming and eventually climate change include;
·         Carbon dioxide from industrial exhaust gases after burning fossil fuels
·         Methane gas produced by decaying organic matter
·         Chlorofluorocarbons(CFC’s) used in refrigerators and spray cans
·         Water vapour
The mitigation to climate change is to lower the rate of release of green house gases into the atmosphere. This can be done by;
·         Promoting afforestation since trees act as carbon absorbers
·         Banning production and use of chlorofluorocarbons
·         Promoting efficient use of energy in homes and industries
·         Slowing population growth rate by prompting family planning-This reduces the number of people likely to cause climate change
·         Creating awareness of activities that cause global warming and suggest possible solutions
The predictable effects of global warming and climate change are warmer earth. The warmer temperatures may cause;
·         Increase in the evaporation rate
·         More areas will encounter forest and bush fires
·         Some areas will become drier while others will become wetter
·         Heating the sea water will cause it to expand thus raising sea level
·         Food production will fluctuate, increasing in some areas and declining in others
·         Loss of bio-diversity as a result of change in habitats
·         Extinction of certain species

Kenyan University Graduates: Navigating the Abyss of Disillusionment

On Friday, at least 6 universities held their graduation ceremonies, marking a momentous milestone for countless Kenyan students. Congratulations, you did it! After years of late nights studying, early mornings in lecture halls, and what seemed like endless exams, you've finally earned that coveted degree. As you see your name on the graduation booklet, visions of the bright future ahead dance before your eyes.  Yet beyond the congratulatory speeches and applause, a harsh reality awaits. The challenges facing university graduates in Kenya today are vast, and the chasm between the idealistic promises of academia and the pragmatic difficulties of the real world yawns wide. Suddenly, the theories that shaped your years of study ring hypocritical when faced with the hard practicalities of life after the university gates close behind you. For many, the days following graduation mark the beginning of a disillusioned struggle to find purpose and place. The university experience, meant to ...

We're Working Teens to Exhaustion: Why Kenya Needs Later School Start Times

  Photo Courtesy| Elvis Ogina In Kenya, a silent struggle rages on as adolescents are pushed to their limits, attending school with early morning start times. Kenyan teens are working themselves to exhaustion. As a teen in Kenya, especially in boarding schools, early mornings are just a way of life. You’re told you need to work hard to succeed, so you push through the fatigue hoping for the best.  Scientific studies have pointed out that teenagers naturally have later sleep schedules. So, forcing them to wake up at the crack of dawn is completely counterproductive. Teens and sleep patterns Teens need more sleep, simple as that. Most teens can’t fall asleep before 10 p.m., even when they get in bed earlier. Waking up at the ungodly hour of around 5 a.m. for school means that most teens get an average of 6 hours of sleep contrary to the recommended 8 hours. Such a schedule is a challenging ordeal even for adults, and it underscores the sheer physical and mental toll that early s...

High Heels: When Fashion Takes a Toll on Your Bones and Joints.

You love how your favorite pair of stilettos lengthen your legs. High heels may look stylish, but your back pays the price. Our bodies aren't created to walk on the balls of our feet or with our weight shifted forward.  Have you ever wondered what those high heels are doing to your feet, ankles, knees, and back? Progressively, wearing stilettos affect your posture, mobility, and health.  Posture and Gait When you slip on a pair of high heels, your whole body adjusts to an unnatural position. Your posture changes, and your gait changes. Gait is a person's manner of walking.  First, your pelvis tilts forward, causing your lower back to arch. Your knees are forced into hyperextension, which can cause pain and damage the joint. Normally, your heel hits the ground first when you walk, but in high heels, your weight is shifted forward onto the balls of your feet. Your balance and stability are compromised, making you more prone to falls and fractures. The overall rate of high-h...
