The land in Burundi is arid and not arable. “Land fragmentation, stagnant or declining yields, falling soil fertility, the absence of inputs and improved breeds of livestock, and low levels of technical knowledge have prevented farmers from boosting production and increasing their incomes.” (New Agriculturalist) A potential result of this land fragmentation and falling soil fertility would be that the land would become so arid that no crops would grow. However, the country is taking steps to…

many challenges humanity would have to overcome in order to change from fossil fuels used to renewable energy sources.

During this period, oil, coal, and natural gas continued to grow; and this increases were much higher the increase in renewable energy. Fig. (1.1) shows the growth in consumption of fossil fuels such as oil, coal, and natural gas as…

to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being about one million times denser than that of the sun. A single sugar cubed amount of white dwarf would weigh approximately one tonne. Its volume comparable to that of the earth, and it’s mass comparable that of the sun. A white dwarf has a faint luminosity which comes from the emission of stored thermal energy. The nearest known white dwarf star is Sirius B, the smaller…

magma plume and composite cone volcano. The eruption of Mount Tambora sent molten rock more than 40 kilometres high and blew out a cloud of ash that covered a million square kilometres. Mixed in with the 30 cubic kilometres of rock was 50 million tonnes…

It is well know that there is an ongoing plastic debris epidemic with an estimated 8 billion tonnes of plastic waste being dumped into the ocean each year (Walter, 2015). With the increasing growth of the human population and the ever expanding affluence of lower income countries plastic waste is only going to increase. Marine ecosystems will be the brunt of this crisis with most terrestrial plastic waste ending its journey in the oceans. The most fragile ecosystems, coral reefs, will be the…

People in this world, even to this very day still yearn for anything they want and perform actions in order to achieve their goals. There have been several instances where we have failed to take time and think about the consequences and impacts our actions could have on society. For the past few years, Canada and the United States have started to build a pipeline that travels through both…

cliff edge. The landslide continued its path of destruction for another two days, after which the hotel finally succumbed to the crumbling cliff and slipped into the sea. According to the British Geological Survey, the slide caused about one million tonnes of silty clay to fall into the sea, creating a semicircular promontory 650 feet (200m) in width and projecting 440 feet (135m) outward from the foot of the cliff. Consolidation and landscaping of the area have left little evidence of the…
