being has been the prime pursuit. In the modern times‚ economic growth is essential to meet these needs of food and personal security. To think of man going backwards‚ wherein he subjugates his quest for a better life‚ would be a myth. Natural resources need to be tapped to provide for artificial comforts and luxuries. And to run these items of luxury‚ we need energy. That conventional sources of energy are responsible for various types of pollution is unarguable. But even when we consider the non-conventional

Water pollution in China started with industrial development and has become more one of the most devastating environmental problems faced by the country today. From the chart‚ we can see that as the country’s GDP rises‚ the volume of wastewater discharge increases as well. This suggests that to achieve a rise in GDP‚ the environment has to be sacrificed. The reason for this is that wastewater treatment techniques and facilities have fallen far behind from the growth of industrial production and

Most of the water pollution-intensive industries are in National Capital Region‚ Calabarzon‚ and Region III. Food manufacturing industries‚ piggeries‚ and slaughterhouses are the main sources of organic pollution (PEM‚ 2004). A report from a study conducted by the United Nations Industrial Development Organization (UNIDO) in 1999 emphasizes that the situation is

ENERGY RESOURCES Energy is defined as ‘the capacity to do work’. Sun is the primary source of energy. Joule is the standard unit of energy in SI units. Energy utilization is an index of economic development‚ which does not take into account of ill effects/damage on to environment. From 1900 to 2000 population increased by 3 times while energy consumption by 14 times! Energy Resources All energy sources ultimately come from the sun‚ the moon or the earth.

What is land pollution? Land pollution is the deterioration (destruction) of the earth’s land surfaces‚ often directly or indirectly as a result of man’s activities and their misuse of land resources. It occurs when waste is not disposed off properly‚ or can occur when humans throw chemicals unto the soil in the form of pesticides‚ insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface

First‚ it attempts to identify the principal ways in which construction contributes to environmental stress‚ and to quantify the contribution of construction where possible. Secondly‚ it considers the means available to reduce these environmental impacts‚ through improved technology‚ design or changed practices; and it suggests ways in which governments can take action to promote these changes.
