    About four billion years ago, the only place where life can exist was formed. Approximately 71 of the Earths surface is covered with water and the remaining percent comprises the land. As years passed on, changes were made to the world. People grew more technologically advanced and polluted the Earth. Resources became scarce and nations fought each other for survival. Indeed the more people grew more advanced, the faster they destroyed the Earth.     At present,...

Global warming conspiracyThe Great Global Warming Swindle documentary was aired on 8th March 2007 in the channel 4 screen. The documentary was confiscating global warming is not as a result of the green house gases which in turn results from human activities. This contradicts the scientific consensus for the causes of climate change and the campaign for the reduction of these gases. But the documentary was full of confusing and misappropriating information that I need to justify. I will examine...

    Organisms acquire certain traits through various means which have been formulated in several theories. Traits of organism can be traced through successive generations. This change in traits through successive generation is referred to as evolution. The trait acquired may seem to be small but the accumulation through various generations creates a significant change in population. New species arise due to the traits acquired. This is an indication that all species share the same...

    For a long time now, it has been reported that different plant and animal species have been mysteriously vanishing from the face of the earth without any trace (Sunstein 261). As this trend has continued, issues have emerged as to the role that mankind plays in this extinction, as in most cases the blame has been on mans many activities as he tries to make his own life as comfortable as possible.

I have personally observed that compared to all other life forms on this planet, humans are emotional, that is, they allow themselves to be governed by emotion before reason. Plants and animals I believe are rational first before they are emotional. I have observed that no normal dog will attack you unless you provoke it. However, I have seen people on TV and in the movies who were so emotional that they brutally committed crimes just because they liked doing it. Some criminals featured in the...

(Smith)  The proper term for this process is carbonization, and while peat has yet to completely...

In the last four years, over 30 percent of commercial bees have died as a result of colony collapse disorder. There have been various theories that have been developed by scientists to explain the destructive phenomena. The phenomenon has also attracted surprising suggestions on the possible solutions to the problems. The effects of the destruction of bee colonies have been far reaching because of their contribution in agriculture as they pollinate almost a third of the agricultural plants in the...

Atmospheric pollution, mainly caused by human activity, has been known to be the biggest contributor to global warming. The motor vehicle industry contributes to a huge percentage of the pollution. This is through engines that combust fuels rich in hydrocarbons so as to propel them from one point to the other. The combustion of hydrocarbons leaves the environment with such compounds that are known to cause environmental degradation leading to serious results such as global warming. The effects of...
