Ozone Depletion Causes

1704 Words7 Pages

THE CAUSE OF OZONE DEPLETION In this topic, only the anthropogenic causes of the ozone depletion will be discussed. Ozone-depleting substances (ODS) generally contain chlorine, bromine, fluorine, carbon, and hydrogen in varying sizes and are frequently depicted by the general term halocarbons. Chlorofluorocarbons, carbon tetrachloride, and methyl chloroform are important human-produced ozone-depleting gases that have been used in many applications including refrigeration, cleaning of electronic components, foam blowing, air conditioning, and as solvents. Another important group of human-produced halocarbons is the halons, which contain bromine, fluorine, carbon, and chlorine and have been mainly used in fire extinguishers. These chemicals …show more content…

The hydrogen makes them less stable and ergo less damaging to the ozone layer. Except for a few HCFCs already in utilization in Canada - mainly utilized as refrigerants - most HCFCs have been developed for utilize as transitional chemicals to supersede the more damaging ozone-depleting substances, mainly CFCs. HCFCs have only two to five per cent of the ozone-depleting potential of CFCs, which makes them a good transitory supersession for applications where alternatives consummately safe for the ozone layer are not yet available. HCFCs are mainly utilized for foam blowing, refrigeration and air conditioning, solvent cleaning and to a lesser extent, aerosols and fire …show more content…

It is still not yet in the verge of worldwide depletion. Also, the Montreal Protocol is a very outstanding set of rules that actually saves our ozone, which, in turn, conserves our environment. The stratospheric ozone issue has shown us that mankind is quite capable of significantly affecting the atmosphere on an ecumenical scale: the most striking effects of CFCs, which are emitted mostly in the north, are visually perceived as far away as possible from the sources, namely over the South

    "Hydraulic fracturing, the process of extracting oil or gas by forcing fluids into the ground to fracture shale rocks, at the Eagle Ford Shale Play has produced more oil and natural gas but at the cost of environmental hazards and affect human health. The part of the process that creates the environmental hazards is the fracking fluids that are forced into the ground. For each fracking job, these fluids are comprised of 1 to 8 million gallons of water and 40,000 gallons of chemicals. Some of the 600 chemical carcinogens and toxins in the fracking fluids are lead, radium, uranium, mercury, methanol, hydrochloric acid, ethylene glycol, and formaldehyde. Once the fracking job is done, about 50 to 70 percent of fracking liquids are left in open

    Because of this, it is hard to tell the extent to which the greenhouse gases destroy the ozone (Oppenheim 89). In addition, scientists have not had observations from space for a long enough period to see long-term trends in the climate. Scientists also lacks the techniques to detect the small changes involved in climate change. This lack of technologies and technique to predict or tell what is taking place in the space limits or hinder the climate change mitigation strategies (Oppenheim 89). Fortunately, satellite-born systems are now being developed to measure the radiation balance.

    Although, it is required that we give it that push to do so. In a way, we are killing ourselves and many other forms of life on earth. We do this by simply driving our cars to work everyday, powering our factories, and in general emitting large amounts of CO2 into our atmosphere. When we begin doing this, the greenhouse effect goes from sustaining our lives to putting it in danger. Some of the hottest years in recorded history have occurred during the 21st century.

    I. Introduction Long ago, since ancient time humans have been using energy and striving for the betterment of themselves, it all began with the use of tools which led to the discovery of fire, from this great breakthrough, humans evolved exponentially. Eons have passed and humans are still using fire to ease their daily lives from cooking, mobility and electricity, but due to the increase in advancement of technologies, it has also increased damages to the planet, thus the governments had started to move towards a producing or replacing the old harmful substance to a less harmful ones, but since one of the most used and one of the highest cause of ozone depletion is chlorofluorocarbon (CFC), it has been banned from production due to the Montreal Protocol 1991, one of the causes as to why it was banned is one of the chemicals it contain is chlorine, once a certain condition is met it depletes the ozone layer, ergo with earth shield compromised more harmful ultraviolet rays will get into the planet, thus only the reservoir of CFC are being used today, now it’s a race against time to replace this CFC with other materials that is less harmful and either as or more efficient than it. There are not a lot of ways to replace chlorofluorocarbon. Some of the most prominent ones are hydrochlorofluorocarbon (HCFC), hydrofluorocarbon (HFC) and magneto caloric effect (MCE).
