The Importance Of Environmental Friendly Technology On The Environment

In the past decade, natural disaster and climate change, mainly global warming have caused more and more people look at the environment carefully. More and more people address this problem seriously and stay to reflect on this question, ‘Is it the human activity that cause these problem?’ Because of this question, mechanical engineers try to develop technology that is environmental friendly to protect this Earth, since we are responsible at taking good care on Earth. After a long development, there are some success among different areas in mechanical engineering. However, there is a main debate among engineers about whether nuclear propulsion is also environmental friendly. Some said it can be wonderful energy resources for human being, some

Pollution problem has direct impart to human living standard, so technology should not cause harm to human, otherwise who would like to use it. Therefore, environmental friendly technology should protect human being as well by preventing pollution. Barreras et al. made a great concept in this area, “[non-environmental friendly technology] are responsible for the emission of a very large part of the total amount of pollutants contained in the air, namely 40% of solid particles, 25% of CO2,….”(2012). They taught that non-environmental friendly technology can produce a lot of toxic gases which engineers should be aware with. It is because air pollution not only affect the environment, such as global warming, but also human activity and health, like acid rain and toxic fog. Another example given by Kempton and Letendre (1996) show that other pollution also should be considered in environmental friendly technology in order to protect human being. “[non-environmental friendly technology] has the disadvantages of ... environmental lead pollution during manufacturing and recycling” (1996). From this example, lead pollution during manufacturing and recycling become a disadvantages of a non-environmental friendly technology. Like lead pollution in this example can cause the death of some species, including human. From the examples above, pollution problem cause disadvantage to a technology, which engineers need to prevent, because it is harmful to human being. Therefore, an environment friendly technology should be nice to human being by reducing
