The colonization of Africa began in 1884 with the Berlin Conference. On this conference, the Western European powers decided to split up the land and resources of Africa among themselves (Rosenberg, 2004). This period of history became known as the Scramble for Africa. The Scramble for Africa occurred because as the slave trade ended, capitalists saw Africa as a continent that they could now exploit and through legitimate trade, they found new ways to make money of the continent (Michalopoulos &…

1 INTRODUCTION While humans have been using fire for many thousands of years, we have only recently in our history recognized the benefit of removing smoke from the home. There is little documentation on the history of chimneys and their function in the home. In western civilization there is record of chimneys being destroyed by an earthquake in 1347 (Butler, n.d.).

Not being able to properly sustain has caused some civilizations to decline in the past. Land is taught to be vast, but in reality, little to that thought is true. Instead land is very limited and must be used wisely. Food shortage have played a key role in the down of many empires.

Diary Entry 4: The night had just started to darken; the stars that were coming up as though they were individual beacons of hope that kept people going to see another day. Everyone was scattered around in their makeshift houses; we had been living in a cardboard box for a while now just like everyone around us. As I looked down I could see my ribs sticking out, the piece of an apple I ate to today did not satisfy my hunger; albeit it was the first food I had in three days. The lack of food was…

“Australia needs to do more to address environmental concerns.” Discuss. It is obvious that the Australian nation needs to further correct the adverse state of the environment.

World hunger is undoubtedly one of society’s most (formidable?) issues today. According to Oxford Dictionaries, hunger is “a feeling of discomfort or weakness caused by lack of food, coupled with the desire to eat. ” We are able to produce more than enough food to feed our large population, yet over 800 million people around the world, or one in nine, do not have enough food to eat. Developing nations __ hold the vast majority of 98% of the world’s undernourished people; however, there are some…

(a) Previous studies on climate change Climate is an essential determinant for agriculture. In regions like Central America, the climate is quite variable and there are problems related to droughts and floods that directly affect food production. Also, climate related insect infestations, weeds and diseases tend to cause damage in developing countries such as those in Central America (Diana et al., 2013). The specific case of South America was addressed by Mendelsohn and Seo (2007). Using data…

Nations has predicted that, by 2050, the world’s population will be 9.6 billion and reach 10.9 billion by 2100 (“Don’t Panic” 1). Problems facing these future generations include resource depletion and shortages, overpopulation, and pollution. Desertification and soil exhaustion rates are increasing as farmers produce more food for a growing population (Otterpohl 3). Energy and water resources are depleting…
