The essay urges you to develop skills in recognising organisms whose survival is intrinsically linked to the quality of water. Conversely you can gauge the quality of the surface water through a cursory inspection.

With a rich experience of engineering, construction and operation of power plants, NTPC is one of the most efficient power companies in the world with operations that match global standards.

Common day household activities release harmful toxins into our indoor environment. But indoor plants may provide a valuable weapon in the fight against rising levels of air pollution in the home. Such plants are not only decorative, but are surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings. Studies generated at NASA recommend that you use 15 to 18 good-sized houseplants in 6 to 8 inch diameter containers to improve air quality in an average 1,800 square foot house. The more vigorously they grow the better job they'll do in improving the air quality in your homes.

Ocean Acidification, Sea Level Rise And Extreme Events-DRTC 2013 Concludes.

Glaciers work as a water tower, sustaining the lives of millions downstream. The volumes of these glaciers vary - remaining sensitive to global temperature conditions. The glaciers have embedded within it many lakes which follow a seasonal pattern of freeze and thaw. With continuing warming trends, many glaciers are melting rapidly, giving birth to a large number of glacial lakes. These ‘moraine dammed’ lakes are comparatively feeble and its unexpected outburst is a threat to life, asset and infrastructure, downstream.

A study on ‘Earthquake Risk Mitigation Strategies in India (2008)’ by C. Ghosh of National Institute of Disaster Management, New Delhi, states that about 59 per cent of India’s land area is under the threat of moderate to severe earthquake shaking intensity 7.0 and higher.
