Desertification

Human migration is an ancient phenomenon that started along with the subsistence of human beings on earth. It influences human life and the environment around as well; hence it is known as one of the three basic components of population growth of any geographical area (The other two are Mortality and Fertility). Moving from one place to another for many reasons including, for a better living conditions, food, employment, education, business etc. have been taking place since the beginning. When a…

This is one way in which energy is transferred between organisms in an ecosystem. The energy is used for a number of life processes. In a food chain only around 10 per cent of the energy is passed on to the next level. The rest of the energy passes out of the food chain in a number of ways: 1. via heat energy 2. is used for life processes (for example movement) 3. uneaten parts that pass to decomposers 4. is excreted and passes to decomposers. As less energy is transferred at each level…

idea that adjusting the ecosystem’s biodiversity might prove to be more prosperous for the climate without cutting down on the energy demand of the world population. Confinement of livestock has been the primary contributor to the process of desertification. When herds of large animals are forced to be confined within a space, as opposed to being truly free range, it has an adverse effect on the biodiversity. This leaves an imbalance within the ecosystem. The population of free grazing animals…

Growing up I remember my teachers preaching about how we need to take care of our environment. In order to reduce your carbon footprint, they would say “take shorter showers, shut the lights off, and instead of having your parents drive you to a friend’s house, walk.” I always listened to this advice, trying to be as green as I possibly could. Last year I watched an eye opening documentary about our current climate and environmental crisis; however, the documentary didn’t focus on how we drove,…

What do you think of when you hear the word “viking?” Do you think of masculine, Scandinavian brutes pillaging villages? Well, you would not be wrong. However, they damaged more than just the lives of innocent villagers. Now, what do you think of when you hear the word “Iceland?” With its cold, Nordic atmosphere, one would think that Iceland would be able to withstand anything, but that is not the case. Surprisingly, Iceland’s environment is very fragile, and the vikings did their fair share to…

Since the 1859 publication of “On the Origin of Species” by Charles Darwin, the theory of evolution has ignited a tumultuous debate on the genesis of mankind, climaxing in intense confrontations between creationists and evolutionists. Creationists believe in the intelligent-design theory, that life did not arise by chance, but was created by some intelligent entity (God), referencing religious text as evidence. On the contrary, evolutionists believe in Darwinism, that through the process of…

In the twentieth century many reached the understanding that disputes are normal in human society, and not necessarily destructive, and that if they do not get out of hand they may have within them a potential for growth, maturity, and social changes, an opportunity for new ways of thinking and new experiences. Because conflicts are an integral part of human interaction, one should learn to manage them: to deal with them in a way that prevents escalation and destruction, and arrives at new,…
