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).
Picture yourself living in the early 70’s and the newest invention is the refrigerator. One of the most used inventions on this planet, it keeps your food preserved and saves you money. Not many people knew that it is producing harmful chemicals into the atmosphere. I will be discussing global warming and the depletion of the ozone layer.
When a foreign substance is introduced to a natural environment pollution occurs. Pollution is destructive and harmful. The amount of pollution has drastically increased do to mankind’s urge to develop. With the industrial revolution came a large amount of pollution. Waste products, toxic gases and poisonous substances were being released into nature. With the amount of pollution today our world is slowly dying. One of the many problems caused by pollution is ozone layer depletion.
Intro. Day after day we harm the environment and we don’t even know we are doing it. By creating new technology, paper, waste products, and new chemicals we advance through with a consequence. The consequence of pollution. Pollution harms the environment thinning the ozone layer.
Rahul Edassery Professor Brown Grade 10IO Chemistry 25 April 2016 Ozone Depletion (A threat to Mankind): Halons Picture this, a turtle without a shell, a car without an engine. Have you ever wondered what the state of planet Earth would be without the ozone layer? According to Severn Cullis-Suzuki, ozone depletion is difficult to fix and it is best to not make it worse: “You don’t know how to fix the holes in our ozone layer.
UV radiation is a form of energy from natural and artificial sunlight. Excess amounts can cause damage to DNA in the skin. Although some argue tanning is good for you because it helps form a “base tan” and the UV exposure time is controlled. The truth is, each time you lay in a tanning bed, it increases the risk of developing skin cancer
On an average day there are about a million people who go tanning on a regular basis, and of those million people, most are younger, between the ages of sixteen and twenty-nine (Hochman). People who use tanning beds before age of thirty-five have a seventy-five percent increased risk of developing melanoma (Fellingham). There are approximately 65,000 new cases nationwide of melanoma and about 9,000 deaths each year from the most preventable disease (Salsberg). Researchers said that there is a death every hour because of melanoma
roduction The environment serves us three purposes: it’s our living space, our supply depot and our waste repository. But through human existence and activity, the environment is gradually “falling apart.” This essay aims to highlight how air pollution and climate change go hand in hand and how they both influence the global natural environment, society and all of society’s systems.. Air pollution refers to the release of harmful substances into the Earth’s atmosphere, which in turn, has detrimental effects on the natural environment.
There is melanoma, the most deadly skin cancer which also happens to be the most common. Just in melanoma there has been more than 3.5 million diagnoses every year. Melanoma is also more commonly diagnosed in girls 15-29 than of boy of that exact age. Indoor tanners have also been diagnosed with other varying types of skin issues. The risks of one receiving one of these issue is drastically increased from only one session of tanning.
- Parabens have been proved to penetrate the skin and can found in blood minutes after applied. Parabens also break down into formaldehyde, which is a substance that causes cancer. It has also been proven that paraben has the ability to act as an estrogen which is plays a role in development of breast cancer. Also, it interferes with the function of the endocrine system. Paraben can increase prevalence of early puberty in girls.
When that happens it can actually deposit into our female predominant tissues or our gynecological tissues and start causing growths to happen. What we need to start doing is avoiding our exposure to those chemical and start flushing them out of our system.” The products that most people use to fulfill their idea of beauty cause health problems. This doesn’t mean to throw out all of your makeup, but what it does mean is to check all of your makeup and see what they rate on the toxic scale and if they are a 4 or about they should be thrown out. The doctor also says you should check your toothpaste or other materials that have chemicals in
Cause-effect relationships: climate change, ozone layer depletion, ultra violet radiation and biodiversity changes Ultraviolet radiation and ozone layer In recent years, along with the general deterioration of the environmental situation, climate change, pollution of the atmosphere and the aquatic environment, a problem has arisen associating with the effects on the human health of excessive ultraviolet irradiation. The global process of degradation of the Earth's ozone layer, one of the manifestations of which is the formation of "ozone holes", led to the disruption of the usual mode of natural UV radiation. The sun is the main source of optical radiation coming to the surface of the Earth from space.
