Environmental problems Everyone has heard about global problems. Television and the press often writes about storms‚ droughts‚ melting of glaciers‚ or hunger in Africa. But not too many of us know the details‚ and the stories behind those problems. These days the biggest environmental problems are: Global warming‚ Pollution‚ drought‚ overpopulation‚ deforestation‚ Endangered species. Let’s start from global warming. Global warming is the process by which the Earth’s average atmospheric temperature

Effect of temperature and humidity on the transpiration rateof the whole mushrooms P.V. Mahajan * ‚ F.A.R. Oliveira‚ I. Macedo Department of Process and Chemical Engineering‚ University College Cork‚ Ireland Abstract Water loss or transpiration is an important physiological process that affects the main quality characteristics of fresh mushrooms‚such as saleable weight‚ appearance and texture. A loss in weight of only 5% may cause fresh produce to lose freshness and appear wiltedand it is an

A reaction paper for the article: TROPICAL CYCLONES ‘LIKELY TO INTENSIFY’ According to the article‚ Tropical cyclones hitting East Asia have grown increasingly fierce in the past 30 years and are likely to intensify further with global warming. Noticeable increases of greenhouse gases over the globe could influence rising sea surface temperature and change large-scale atmospheric circulation in the Western North Pacific‚ which could enhance the intensity of tropical cyclones hitting land over

A rare‚ early October blizzard the dropped three to four feet of snow following two inches of rain has devastated South Dakota‚ after as many as 100‚000 head of cattle may have died following the October 3rd storm. The losses have ranchers reeling both financially and emotionally‚ as they are tasked with gathering and burying tens of thousands of dead animals. John M. Glionna with The Los Angeles Times reports on what made the story so deadly: The blizzard hit just days after 80-degree weather

WEATHER Clouds: Where two masses of air from different sources and with different characteristics meet‚ Boundary lines are formed where the cooler and heavier air runs under the warmer and Lighter air and compels it to rise. As in the previous case the expansion and cooling of this air results in the formation of Clouds spreads as a more or less continuous of stratiform clouds. Air may be forced to rise up the sides of mountains and high grounds towards which the wind is blowing..The consequent

5. The problems of ecology. What should we do to protect our planet? Since ancient times Nature has served Man‚ being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But with the development of civilization man’s interference in nature began to increase. Large cities with thousands of smoky industrial enterprises appear all over the world today. The by-products of their activity pollute the air we

2.1. Geology Jalpaiguri Districts almost entirely covered with alluvium expect that a narrow belt of hard rock is exposed along the northern border of the districts. The geological formations found in the districts are given below in the order of increasing antiquity. • Recent and Sub-Recent: Alluvium and other soils boulder and people beds. Miocene: - Siwaliks: - Sandstone with clay and lignite. Permian (Lower Gondwana):- Sandstone shape with Genes of Graphite coal. • Pre-cambnan (Buxa series):

Deforestation Plants give us oxygen which is the most important thing for our survival. They undergo a process of photosynthesis in which they give out oxygen and take carbon dioxide. Plants consume the air‚ sunlight and the carbon dioxide we breathe out to make food and oxygen. So if trees are cut‚ plants will not produce oxygen and the concentration of carbon dioxide will increase. Increase of carbon dioxide in the air is harmful for human beings and also disturbs the water cycle and hence the
