Provide a 12 pages analysis while answering the following question: Green Chemistry Principles in 2020. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The progress of human civilization, especially in the post Industrial Revolution era, witnessed a dynamic shift of the human race from agriculturalist approach to urbanization for the purpose of Industrial expansion. In order to secure increasing amount of place for establishing industries, more torture over environment commenced – starting from random deforestation to use of natural fuel resources in the industrial sectors, capable of emitting harmful gases and biohazards and created negative impact on the global environmental balance. During the Post World War II period, while capitalism and industrial domination became major resources for the powerful nations across the globe for their respective prosperity, the situation of environmental crisis took even more critical turn due to abundant use of nuclear elements for creating electricity (Krech, McNeill, and Merchant, 2004). In addition to this situation, most of the ruling nations of the world, in their quest to show their respective supremacy over one another, started experimental blasting of nuclear bombs and missiles, which amounted to massive destruction of natural resources, leading to one of the greatest threats against progress of the modern civilization, global warming. Once the Cold War between the United States and the Soviet Union was over during the 80s and the world revived from the impending threat of witnessing a nuclear war, consequently, humanistic part of the scientific activism also witnessed that human arbitrariness over experimenting with nature has extended to such an extent that immediate measures, if are not adopted, then there is always a great risk that the entire human race will be exterminated due to negative effects of natural imbalance (Buell, 2003). Thus, since the later part of the 80s “several environmentally conscious terms entered the chemical arena, e.g. clean chemistry, environmental chemistry, green chemistry, benign chemistry and sustainable chemistry” (Linthorst, 2009). However, compared to other variations of environmental conscious terms in the field of chemistry, “green chemistry” received a great deal of appreciation and has become more familiar among students and aspiring scientists and one of the main reasons behind such wide acceptance of the term can be interpreted in the way that it explained the purpose of science and scientific experimentations by encompassing the ideology of environment friendly scientific approach, consequently, receiving wide range of support among various scientists and scientific associations (Linthorst, 2009). Adequate scholarly proposals have also been made to include green chemistry as a part of school curriculum. This paper will examine green chemistry principles in light of the sustainability issues of 2020. It will try to find out what kinds of changes are required to meet the sustainability challenges of 2020. it is first necessary to talk about the environmental issues and threat of 2020. Then, it will move on discussing the green chemistry principles in light of sustainability issues of 2020.
