UNIT I HUMAN ACTIVITY IMPACT ON THE ENVIRONMENT Read the quotation below. What does it tell you about? “Earth gives enough to fulfil each man's necessities, not every man's covetousness.” Mahatma Gandhi an Indian politician LEAD IN Humanity's effects on the Earth have grown more and more significant since becoming the dominant species on the Earth. Never before in our planet's history have human activities had a greater impact on the environment. 1. Before you start, make sure you know these words. Check them with your dictionary if necessary. advancement significant responsible vapour salinity harmful emission widespread channelization irrigation watershed run-off triggering to ramify to diffuse

Why is the atmosphere important? What is air pollution? How can air quality affect health? How might humans be changing Earth’s climates? HUMAN IMPACT ON THE ATMOSPHERE The increasing human population and the advancement in technology have not only become significant factors in the variations in world climate but are also responsible for the various changes in atmospheric conditions including air pollution. The human influence on global climate is due to the following mecha nisms: Gas emissions CO2 – industrial and agricultural Methane Chlorofluorocarbons (CFCs) Nitrous oxide Aerosol generation Thermal pollution Dust addition to ice caps Deforestation Overgrazing Extension of irrigation
Krypton 85 Water vapour Miscellaneous trace gases Alteration of ocean currents by constricting straits Diversion of fresh waters into oceans The problem of carbon dioxide (CO2) emission has become a major environmental concern. Since the beginning of the Industrial Revolution humans have been taking stored carbon out of the earth in the form of coal, petroleum and natural gas, and burning it to make carbon dioxide, heat, water vapour and small amounts of sulfur dioxide (SO2) and other gases, which are responsible for air pollution, greenhouse effect, increase in surface temperature, or in other words, global warming. By 2050, it is possible that the increase in global surface temperatures ranges between 1.4 and 2.2 degree Celsius. The impact of human activities on the atmosphere is more because the atmosphere acts as a major channel for the transfer of pollutants from one place to another. It is in this way that harmful substances are transferred long distances from their sources of emission. Another example of the possible widespread and ramifying ecological consequences of atmospheric pollution is provided by acid rain. In recent years, the greatest attention has been paid to the role of CFCs, the production of which has been rising in last few decades. These gases may diffuse upwards into the stratosphere where solar radiation causes them to become dissociated to yield chlorine atoms which react with and destroy the ozone present there. The Antarctic ozone hole has been identified through satellite monitoring. In fact, air pollution and its variability both in space and time is more due to human action. 2. Match the terms 1-5 with the definitions A-E. 1. Water vapour A) intensive grazing by animals, for example cattle, sheep or goats, on an area of pasture. 2. Thermal pollution B) gas which makes up less than 1 % by volume of the Earth's atmosphere, and it includes all gases except nitrogen (78.1 %) and oxygen (20.9 %). 3. Deforestation C) one state of water within the hydrosphere.
4. Trace gas D) the degradation of water quality by any process that changes ambient water temperature. 5. Overgrazing E) the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. READING 2: Do you know? Why is the hydrosphere important? What is water pollution?

The (2)_______ civilizations have developed in river valleys. This is also true of medieval (3)_________ and other developments, and all modern developments are related directly or indirectly to water. The main concern is that by using water, humans have influenced both its (4)_________and quality. Earlier, the influence of human activity on water (5)_________was limited but now this has become a major problem of environmental

However, there are many (7)_______in which humans influence water, for example, by direct channel manipulation, modification of watershed characteristics, urbanization and pollution. The (8)_________ of dams and reservoirs is widespread throughout the world for irrigation, to generate power or to provide a reliable source of water. More than 700 (9)______ have been built worldwide and their number is increasing year after year. In countries like Brazil, Argentina, China, run-off of water has been regulated by water reservoirs. The (10)_________of human activities is especially marked in Africa and North America where about 20 per cent of total run-off is now controlled. The impact of dam, construction is apparent in the form of change in ecosystem and (11)_________ conditions. The environmental (12)__________of dams include subsidence, earthquake triggering, transmission and expansion in the range of organism, the build-up of soil salinity, changes in groundwater levels, water logging, deforestation, etc. The process of urbanization has a considerable impact, in terms of controlling rates of erosion, the delivery of (13)___________to rivers and influencing the nature of run-off and other hydrological characteristics. The impact of urbanization can be summarized as follows: Removal of trees or vegetation. Construction of houses and sewerage lines. Construction of septic tanks. Diversion of nearby streams for public supply. Accelerated land erosion. Larger quantities of untreated waste into local streams. Pollution of streams and wells. Drilling of deeper, large capacity industrial wells. Increased use of water for domestic and commercial purposes.
