Essays on Ozone Depletion

Introduction

Are humans threatening the survival of our planet by disrupting the ecosystem? Marvin Gaye and the public believed this to be the case in the 1960’s and 1970’s when the modern Green Movement first began. Gaye sang “Poison is in the wind that blows from the north and south and east. Radiation underground and in the sky, animals and birds live near by all die. What about this crowded land, how much more abuse from man can we stand?” . Greenhouse effect, ozone layer depletion, ocean poisoning, topsoil depletion, food chain poisoning, acid rain, pollution along with demands ...

Overpopulation is the most serious problem faced by humans today. Population continues to expand at an alarming rate forcing depletion of natural resources. The demand for food, shelter and water causes havoc on the natural biodiversity of the Earth. Many species of plant and animals are eradicated and the freshwater resources are drained beyond recovery. The existing resources are not sufficient to sustain the increasing population. The increase in the demand for consumption of goods has led to a change in the cultivation pattern resulting in biological imbalance. Changes in the size of population affect all issues which range ...

Introduction

Over the course of the last few decades, global pollution has overwhelmingly been on the rise. As years go by - the humans' way of thinking evolves. Hence, the technological aspect of life keeps on advancing rapidly at the expense of contaminating our planet. Similar to other elements associated with human life, the natural environment is also undergoing a continuous change. There is the unchallengeable need of developing knowledge of the issues that characterize this change. The modern world is experiencing an increase in the natural calamities and varying weather patterns. These changes are primarily associated with the environmental ...

The ozone is a layer of gasses in the stratosphere that protects life on Earth against ultraviolet rays from the sun (Aggarwal et al., 1). Anthropogenic activities leading to the emission of nitrous oxide and chlorofluorocarbons can result in the destruction of the ozone layer. Organohalogens also contributes to the destruction of the ozone layer (Lee, 858). The depletion leads to secondary ozone layer close to the ground called terrestrial ozone layer that is responsible for the degrading effects on humans, plants, and their environment. In the article published on August 27, 2009, on the New York Times, Dean ( ...

Stratospheric Ozone Depletion

Ozone depletion is a natural phenomenon of the earth’s stratosphere due to the presence of free radicals that are from natural causes such as volcanic activity. However, as man evolved, he discovered his environment and built industries during the industrial revolution. These industries emitted tones of pollutants into the atmosphere, including compounds Ozone Depleting Substances. The continuous use of CFCs also contributes to the effect significantly. The worst case of ozone depletion ever recorded happened in 2006, during winter and early spring in Antarctica. That sounded a loud alarm to environmental scientists, political leaders and civil organizations come ...
