Environmental Studies - Essay ExampleWe shall look at the influences that comprehension has made in the push sector, climate change and agriculture among others. In the scientific world, agriculture is a more recent human activity that humans experimented. Human beings were originally hunters and gatherers who survived by killing ill-advised animals in the jungle. Then agriculture was accidentally discovered through mans scientific exploration. humankind began cultivating land in order to get food. Studies have shown that hunters and gatherers were more healthy, well nourished than the latter farmers. In fact, agriculture did not improve the lives of humans and the skeletal evidence revealed that hunters and gatherers were healthier than the farmers were. Agriculture needed enormous amounts of land for cultivation, and this led to the destruction of forests and animals natural habitat. The muscle threshold of plants then decreased as nigh natural vegetation was destroyed and cle ard to make way for cultivation. This interfered with the natural button cycle since animals get energy from plants, which in turn obtain the necessary energy from the sun for photosynthesis. near of the percentage of the worlds energy relies on plants. If plants are destroyed, the energy needed by most organisms is decreased, and this can have devastating effects. This causes animals to face extinction as the energy cycle is affected by mans activity, which in this case is agriculture, a scientific invention. Therefore, there is evidence that as often as cognition has helped the environment, it also hurts the same environment by altering natures prevalent activities (Rees, web). The clearing of natural vegetation gives way to soil erosion. In todays world, oil is the only form of energy that humans have resulted to use. It is interestingly hilarious that man secures oil more than food. This is because energy is vital for most activities and oil is the usual form of energy employ to meet the demands of man. Research in America has shown that for every 2.3 calories of food energy produced there is a calorie of fossil energy used (Manning, web). This is devastating to the human life because as more oil is used to produce food energy that is required by a growing population, levels of pollution in the environment continue to increase. All this is attributed to science inventions among other factors such as population harvest-tide and industrialization. The more industrialized we get, the more scientific inventions are discovered which continue to damage the environment in an attempt to meet the needs of man. In the twentieth century, engine fueled cars dominated the roads which made transportation and communication easy. However, these advancements usually have a negative impact on the environment. For example, the greenhouse effect is caused by emission of gases into the atmosphere, which comes from combustion of fossil fuels and oil. scientific adva ncements in chemistry have also had a profound effect on man (Griffith, web). For example, in the cultivation of wheat in leading countries, fertilizers containing nitrogen-bearing compounds are used to speed up the growth and maturity of wheat. However, studies show that these chemical compounds have adverse effects on human health. A look for carried out showed that a child born in rural places producing wheat based on nitrogenous chemicals has high chances of suffering birth related defects compared to a child born where wheat is not
