Slide 6: environmental degradation INTRODUCTION : INTRODUCTION The landmark report of the World Commission on Environment and Development, entitled "Our Common Future", warned that unless we change many of our lifestyle patterns, the world will face unacceptable levels of environmental damage and human suffering. The Commission, echoing the urgent need for tailoring the pace and the pattern of global economic growth to the planet's carrying capacity, said that: "Humanity has the ability to make development sustainable and to ensure that it meets the needs of the present without compromising the ability of future generations to meet their own needs." Meaning : Meaning Environmental degradation is the deterioration in environmental quality from ambient concentrations of pollutants and other activities and processes such as improper land use and natural disasters.  Erosion of the quality of natural environment caused, directly or indirectly, by human activities. QUOTES : QUOTES Modern technology, owes ecology an apology _ Alan M Eddison Don't blow it -good planets are hard to find -Qouted in times Because we don't think about future generations, they will never forget us. -Henric Tikknen Nature provides us free lunch, but only if we control our appetites. -William Ruckel Shaw, business week They kill good trees to put out bad news papers I am the earth , you are the earth, the earth is dying, you and I are murderers -Ymber Delecto We abuse land because we regard it as a commodity belonging to us. when we see land as a community to which we belong we may begin to use it with love and respect. -Aldo Leopold Manifestation of environmental degradation : Manifestation of environmental degradation INVENTION….. : INVENTION….. THE DA VINCI TOWER- ROTATING SKYSCRAPER IN DUBAI :  The Underlying Causes of Environmental Degradation Environmental degradation is a result of the dynamic inter play of socio-economic, institutional and technological activities. Environmental changes may be driven by many factors including economic growth, population growth, urbanization, intensification of agriculture, rising energy use and transportation. Poverty still remains a problem at the root of several environmental problems. Causes Slide 14: Natural factor Global warming Depletion of ozone Social factor Population Poverty Urbanization Slide 15: Social factor Population India supports 17 per cent of the world population on just 2.4 per cent of world land area. It’s current rate of population growth at 1.85 per cent continues to pose a persistent population challenge. In view of the linkages between population and environment, a vigorous drive for population control need hardly be over emphasized. Poverty Poverty is said to be both cause and effect of environmental degradation. The circular link between poverty and environment is an extremely complex phenomenon. Inequality may foster unsustainability because the poor, who rely on natural resources more than the rich, deplete natural resources faster as they have no real prospects of gaining access to other types of resources. Urbanization During the past two decades of 1971-91, India’s urban population has doubled from 109 million to 218 million and is estimated to reach 300 million by 2000 AD Slide 17: Lack of awareness and infrastructure makes implementation of most of the laws relating to environment, extremely difficult and ineffective. INSTITUTIONAL FACTOR Slide 18: Global warming is defined as the increase of the average temperature on earth. As the earth is getting hotter, disaster like hurricanes, draughts and floods are getting mare frequent. Global warming Acid rain : Acid rain Slide 20: The term acid rain refers to what scientists call acid deposition.  It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term.  From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen.  The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution.  As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain.  Some scientists concluded that human production was primarily responsible, while others cited natural causes as well.  Recently, more intensive research has been done so that countries have the information they need to prevent acid rain and its dangerous effects. The levels of acid rain vary from region to region.  In Third World nations without pollution restrictions, acid rain tends to be very high.  In Eastern Europe, China, and the Soviet Union, acid rain levels have also risen greatly.  However, because acid rain can move about so easily, the problem is definitely a global one. Affects of acid rain : Affects of acid rain The sculpture when it was first made The sculpture now. PREVENTION : PREVENTION Today's society becomes ever more rapidly vulnerable to natural disasters due to the concentration of populations in mega-cities. Additionally, changes in the global environment threaten us with the possibility of severe typhoons, rising sea levels, droughts, among others. Considering these rapid changes of ambient conditions, vulnerability has increased due to growing urban populations, environmental degradation, and a lack of planning, land management and preparedness. Environmental disasters in many cases are effected by human usage of natural resources. They take place especially because of the negative impact of the over-exploitation of natural resources. Spatial planning and land management provide various tools to prevent natural hazards. The prevention of catastrophes in general is a consideration of spatial planning and land management on the regional and local level Slide 23: Degradation of marine ecosystem due to oil seepage.
