OZONE LAYER DEPLETION
The ozone layer or ozone layer is a region of Earth 's stratosphere that absorbs most of the sun’s ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth 's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometres (12 to 19 mi) above Earth, although its thickness varies seasonally and geographically. Ozone layer depletion is one of the most serious problems faced by our planet earth. It is also one of the prime reasons which are leading to global warming. Ozone is a colourless gas which is found in the stratosphere of our upper atmosphere. The layer of ozone gas is what which protects us from the harmful ultraviolet radiations of the sun. The ozone layer absorbs these harmful radiations and thus prevents these rays from entering the earth’s atmosphere. Ultraviolet radiations are high energy electromagnetic waves emitted by the sun which if enters the earth’s atmosphere can lead to various environmental issues including global warming, and also a number of health related issues for all living organisms.

Severe air pollution, as the one experienced in Utah’s Wasatch Front and surrounding counties can have very dangerous effects on the health of individuals constantly exposed to it. In Utah, smog and air pollution is caused by inversion. Inversion is when the air closest to the Earth is colder than the air above the lower atmosphere. Inversion is common when cities or high-pollution areas are surrounded by mountains, trapping the air released by emissions in a cloud-like dense layer of pollutants. These pollutants, called particulate matter, are miniscule amounts of solid and liquid particles in the air condensed into
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).
For most individuals, they find it hard to understand the importance of asbestos removal. Sure, asbestos is a huge benefactor through thousands of years for its applications; however, if you've never heard of it, asbestos has a lot of health risks. Through this blog, we hope you'll be able to understand these health concerns.
One of the most alarming effects of asbestos exposure is lung problems.
“Most of us- almost all- must take in and give out language as we do breath, and we had better consider the seriousness of language pollution as second only to air pollution (Simon 334).” This is an interesting metaphor Simon writes to introduce one of his next paragraphs. A political, demographical, and even can be a social issue is air pollution. Many Americans or the audience of this essay are aware of this serious issue. This makes for this rhetorical device, a metaphor, just that more interesting.
“African-Americans are about three times as likely to die from exposure to it” than the general population (Stein). Polluted air can destroy the ozone layer that protects us from the sun.
The solution is applying and enforcing government regulations on pollution. I find it ironic that the air that you breathe in order to live can kill you.
People complain about pollution from factories, cars, global warming, and the melting of polar ice caps, yet many people disregard the dangerous that come with fracking. Fracking is the process of injecting liquid at high pressure into subterranean rocks, and/or boreholes to force open existing fissures and extract oil or gas. Fracking is causing an epidemic economically and environmentally. Fracking is continuously destroying the earth day by day. From the endless fracking today’s economy is depleting.

Nearly everyday in our lives, we see banners, magazines, newspapers, as well as posters telling us to be environmental friendly and to stop pollution. But do people listen to the advices? Do people realize that pollution is one of the biggest global killers? Pollution is the number 1 cause of death in the developing world; it kills approximately 10 million people every year. It’s hard to tell when and where pollution began.

Everyday people buy plastic things from the cafeteria, from plastic containers, lids on cups, and things as small as straws, and like 50% of plastic used it will be thrown away after one use. However, do you ever stop and think, what happens to the plastic? If you’re thinking that it just magically goes away you 're wrong. It will most likely end up in a landfill somewhere or in the ocean, and as you may think that your actions do not impact the world, think again. Everyone in the world has at least used one piece of plastic, adding to the problem of plastic pollution and helping certifying the terrifying statisticc that acooording to the 2018 Earth day video, “by 2050 there will more plastic in the ocean than fish”, which almost is impossible to think of.

TOPIC: Global Warming
GENERAL PURPOSE: To Persuade
SPECIFIC PURPOSE: To persuade my audience to aware them about the harmful effects of Global Warming and encourage the audience to help make a difference to stop global warming.
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results.
The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem.
Nowadays, climate change is the biggest concern for the world issue that each country need to find the solution and take action to address that issue. Because climate change causes health problems, so health care is also a big problem, big concern for everyone as well.
I. Climate change
Climate change pose a serious, immediate and global threat to human health and responsibility for taking action to address this threat rests with every person, every community, every leader and every government around the world. That's because global crisis need global response.
Focusing on reducing air pollutants in the Earth’s atmosphere, it creates an environmentally healthy place to live in and encourage people to work together for a common cause, thus making the world a better place.
In order to solve such a problem, a strong understanding is needed. Air pollution is one of the various forms of pollution. It is the presence of foreign toxic substances or pollutants into the air.
