Humans and the Environment - Essay ExampleThe sarcasm of it all is that even the man beings themselves are threatened by their own actions. In agriculture for instance, human beings set out embraced technological developments in farming some of which bring in devastating effects on the grunge. Developments such as the use of modern engineered pesticides have proved efficient in dealing with pests further the successive effect on the survival of the other organisms in the soil is rarely taken into consideration. The pesticides end up killing the worms in the soil which play a very crucial role in ensuring that the soil is well aerated. This development in modes of farming has a short-lived benefit on the farming physical exercise since it may result in improved farming of a given crop species in a given season further in the long run results in the depletion of soil quality (Berry, 2002). on that point has also been an improvement in farming by producing genetically enginee red crops which flourish well during cultivation but most of them put upnot produce viable seeds for replanting. This therefore means that the crop generation is limited to unmatched since it can only be planted once. The genetically engineered crops have been recommended as one of the most efficient ship canal of attaining food sufficiency in countries faced with the food shortage as a result of pocketable farming commonwealths available or due to unfavorable climatic conditions in the countries affected. It has been claimed that the genetically engineered crops are responsible fro the many cancers reported in most people nowadays.

The horses would then be fed and would then be ready to be use another day. This represented a basic description of renewable energy. It is from this that the term horsepower was coined. Human beings have through time developed machines that no longer require the power of the horse to run but instead they rely on the petroleum related terminates which are fossil fuels. Petroleum results after a process that takes millions of years. The rate of use is therefore higher than the rate of regeneration which renders petroleum as one of the sources of non-renewable energy. In addition the exploration of petroleum results into palm of land that is not suitable for agricultural activities. This is unregenerate to the use of horses as sources of energy since horses produce cow dung that can be used as manure for cultivating agricultural crops in the farms. In addition horses used to graze on abandoned fields that were not being used for any agricultural activities (Co urteau, 2007). In order to minimize on the land pollution associated with the exploration of the fossil fuels, some countries have embarked on trying to use other sources of the fuel from what previously used to be considered as petroleum waste. In Canada for example, there are massive investments in place to try and process petroleum fuel from the tar sands (Kolbert, 2007). The other negative diorama of the fossil fuels is the poisonous emissions associated with their use. These fuels produce a lot of carbon while undergoing combustion which in pass on
