Ozone Story and Significance - Research Paper Example According to the study the book Limits to growth: the 30-Year Update examines that industrial production, food production and pollution all contributes to economic and societal collapse in the 21st century. Limits to growth: the 30-Year Update have taken into consideration various factors that cause change in the Ozone layer. These factors include the behavior of the people and their population, and pollution. The variables stated in the book Limits to growth: the 30-Year Update may increase, decrease, oscillate, remain constant or combine with a number of factors to impact on the Ozone layer. The 30-year period given in the book is also long enough to observe, research, and evaluate the effects human activities to climatic changes. The book Limits to growth: the 30-Year Update has played a huge role in setting up the standards of evaluation of the effects on Ozone layer. The book has identified the collect parameters to be used when undertaking a research on the Ozone layer and form s a guideline for other interested researchers as a secondary source of information. The Ozone layer protects the earth from the ultraviolet rays that are sent down to the earth from the sun. There is a great need to protect this layer since it protects people from the possible consequences caused by the damaging rays of the sun. If the Ozone layer in the stratosphere is destroyed by human activities on earth, the effects could be catastrophic. According to scientists, the Ozone layer is a layer of gases that contains much oxygen as compared to the one found around the earth, which protects the earth from ultraviolet rays of the sun. It is found around the stratosphere region of the earth that stretches more than 30 miles above the earth’s surface. This paper outlines that the Ozone acts by absorbing the ultraviolet rays of the sun from reaching the earth. The Ozone layer has been a source of much discussion in the recent years since it has been found to be depleting. The mai n course of the depletion of the Ozone layer is the amassed discharge of CFCs, chlorofluorocarbons, which is a form of pollution. Most recently, there have been strong connections the depletion of the Ozone layer and the climatic changes occurring in the environment. Depletion of Ozone layer affects climate and vice-versa. After many countries called for convection on the effects of global warming to curb the increasing effects of ultra-violet rays, scientists have noted a slow increase in their effects. Ultra-violet rays are responsible for skin cancer and thus ought to be minimized. Moreover, it is important to protect the Ozone layer in the stratosphere to prevent eye cataracts that are also caused by ultraviolet rays.  

Roman Pieta, Marble Sculpture and Christ of St. John of the Cross Essay

Roman Pieta, Marble Sculpture and Christ of St. John of the Cross - Essay Example The essay "Roman Pieta, Marble Sculpture and Christ of St. John of the Cross" discusses that two pieces. This essay will show that they are more alike than their physical and factual differences might suggest. Pieta: This is to be found in the first chapel on the right of the entrance in St. Peter's Basilica, Rome, Italy. A pyramid formation, its dimensions are 68.5† x 76.8†. Using chisel and white marble, Michelangelo created something extraordinary. The triangular pyramid connection reflects the emotional, physical and psychological impact of the piece on the onlooker. These responses are aroused by looking at how the limbs and clothing of the figures are interwoven, curving and blending into each other. The mother's head leans forward, while this is balanced by the way in which the son's is tilted back; her left hand reflects the movement of his left leg. As her right hand holds his head, his completes the circle of contact by holding onto his mother's clothes, his arm resting on her knee. The wholeness of the piece both visually and emotionally portray the bonds of love between mother and child, Church and believer.

Dali was often reported as stating that he dreamed the scene, and was driven by his visions to create a Christ with no thorns, no nails in the hands and no blood. Instead, he wanted to give us a magnificent physical yet metaphysical King of the World. In that, he departed from the more traditional representations of Christ on the Cross . The viewer is looking down, like Christ, the eye is drawn to what Christ is observing and the anatomical perfection of the body calls to mind classical statuary and life drawings. The shadow created by the arms and the cross make a triangle within a triangle and the light surrounding the figure seems to diffuse and re-emerge to illuminate the heavens, and the Earth spread at it's feet. The triangular motif is repeated in the response the picture calls forth, the physical, psychological and emotional are united; here is man, the universe and God, captured in an almost holographic, three dimensional image. This piece signifies Dali's great skill and u nique imaginative power. Comparisons: From a personal viewpoint, there are many comparisons, the chief of which may be the outstanding beauty of the figures of Christ, and in the Pieta, of Mary. The point and
