The environmental issues concerned with using computers because it is not possible to decrease the usage of computer.Our earth is also passing through the global warming, Green house effect and the ozone layer is becoming thin. Today Computers are widely used throughout the globe from any kind of organization to all over the place.The goals are to reduce the use of dangerous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability of useless products and factory waste. It is to be known that as the economy expands, the demand for computing devices increases as business and individuals seek faster way of doing things –‟TheComputing way‟.

In this chapter is addressed the thematic of refrigerants: its historical evolution; properties; legislation applied in the area and future trends. The first refrigerant being marketed on a large scale was ethyl ether (R610), in 1834. Since then, the evolution of the utilized refrigerants was stimulated, initially due to constructive issues in the refrigeration system and later to environmental issues. This evolution may be divided into four generations: 1st use of any fluid that worked; 2nd safety and durability of the equipment; 3rd ozone layer protection and 4th increase of global warming concerns. During the process of evolution many refrigerants were tested to understanding of their properties. Currently, environmental concerns are taken as guide in the search for new refrigerants. The most promising refrigerants to be used in future are the HFEs, HFOs and HFCs with low-GWP, natural refrigerants and blends between (HCs/HFCs and HFCs/HFOs) refrigerants.

Global Environmental Issues

The present study aims to investigate prospective teachers’ (PTs’) and secondary students’ (SSs’) ideas related to environmental issues. A case study design was adopted in this study. SSs (n = 100) who received instruction on environmental issues and PTs (n = 150) who attended courses concerning environmental education were participated in this study. An open-ended questionnaire was designed and used as a data collection tool. Written answers of the participants were analysed in ideographic terms. The results of the study showed that the PTs held a range of alternative ideas similar to SSs. They both linked environmental problems which were irrelevant with cause–effect chain. Yet, PTs provided a more scientific definitions regarding greenhouse effect, global warming and ozone layer depletion as compared to SSs.   Keywords: Global environmental issues, prospective teachers, secondary students, environmental education, greenhouse effect, global warming, ozone layer depletion.

The depletion of ozone layer and green house effects are worldwide problem. Refrigerants are part and source of depletion of ozone layer. As we using these Ecofriendly refrigerants then harm to ozone reduces. These are best option for recently running refrigerants. Eco-friendly refrigerant like hydroflurocarbons and hydrocarbons are replacing chlorofluorocarbons application.CFC is the most important member of CFC refrigerants. This paper, gives alternate to refrigerants that are causes ill effect on environment. Their performance with respect to recently used refrigerant compared. By this comparison benefits of Ecofriendly refrigerants discussed.

Article endeavors to analyze the prophetic guiding principles regarding human behaviors related to plants and trees being an important component of our environment. The discussion mainly deals with the key environmental issues emphasizing plantation and its significance for balancing the equilibrium of the environment. Additionally, it thrashes out that humans are urged to seedling the plantation even the world is to be ended in Islam. The present study is delimited to the present ecological crises faced by society and a great challenge to the globe. The current ecological problems i.e global warming and climate change are interpreted just to analyze the environmental behaviors in Hadith literature. However, a profundity descriptive study has been conducted in the most influential way to examine the prophetic rules for human behaviors related to trees and plants being environment friendly. Furthermore, the existing practices of humans related to such an environmental sphere also been aptly figure out to highlight all possible ways in the light of prophetic guidance to deal with prevailing environmental issues. Inconsistency between religious teachings and human behaviors need the keen interest of religious scholars and social scientists to carefully harmonize both for maintaining the ecological balance in nature.

The most relevant factors that affect climate are astronomic cycles ant their effects on planet Earth and Earth’s orbit around the Sun. They have impact on the occurrence of glacial and interglacial periods at generally 100.000-year frequencies, which were affected by orbital shape variations and effects of greenhouse gases.The youngest geological epoch of the geological history of Earth is Holocene (started with warming) that began approximately 11.000 years BP. In that epoch, the shape of Earth’s orbit around the Sun was nearly circular, close to a perfect circle, and the seasonal contrast was less severe, due to decreased tilt of Earth’s axis from the plane of its orbit around the Sun. However, most scientists are arguing that the causes of rapid climate change are rooted in human activity, and not in its internal orbital variations. The main causes of global warming are increased level of carbon dioxide, but also of methane and chlorofluorocarbons in the atmosphere. These gases are responsible for the greenhouse effect, ozone layer depletion in stratosphere and rapid global warming. In order to set up the legal framework of environmental protection, the United Nations Conference on the Human Environment has adopted Stockholm Declaration in June 16, 1972. About twenty industrial states have ratified in 1987 the Montreal Protocol on Substances that Deplete the Ozone Layer, which has undergone many revisions by London Convention (1990), Copenhagen Accord (1992), Vienna Convention (1995), Kyoto Protocol (1997) and the Paris Agreement ‒ an international universal agreement on climate adopted at the 2015 Paris Climate Conference (COP21). Environmental protection in the European Union is provided for by its primary and secondary law, and the most EU environmental regulations were implemented in the Serbian legislation.
