373 Words Essay on Conservation of Energy

Environment
When we save energy, we also save money. For it reduces the demand for fossil fuels like coal, oil and natural gas. Such fuels form non­renewable energy sources. So the more we use them the less there is to go around. If we depend solely on them we will reach a point where we will go energy- bankrupt. This is why a lot of research is being done on alternative sources of energy which are also renewable. For instance, wind and solar power are renewable. The sun and the winds are always part of our life. And they are abundantly available in many countries. Also, such energy is clean energy which does not emit carbon dioxide, the main culprit in global warming. Today there are many energy- efficient alternatives for…

315 Words Essay on Save Fuel for the Future

Global Warming
Fuel shortages keep occurring in the world from time to time. Most countries have to import fuel to meet their needs. The countries which export fuel are the OPEC nations (those in the Middle East) Venezuela, Russia, etc. Apart from shortages, the price of fuels also fluctuates wildly depending on availability. In India and the US, fuel is sold at subsidized rates. They are heavily dependent on OPEC nations for supply. OPEC nations reduce fuel production to shore up their profits whenever supply exceeds demand and prices fall. On such occasions, oil dependent countries are badly affected. In 2008, a similar scenario arose and prices shot up so much that it created a panic. Long queues were seen outside petrol bunks and there were fewer vehicles on the roads because…

216 Words Short Essay on Hygiene

Environment
It is said, “Hygiene is next to godliness.” It is because we can achieve nothing physically, mentally or spiritually if we are unclean in our body, mind, or soul. Nobody likes an unclean child or adult and a clean one is loved, desired and respected everywhere. First of all, we should keep our body clean. We should have a daily bath with toilet soap or shampoo well-applied to all parts of our body and hair so that not a speck of dust or a drop of perspiration keeps sticking to us. We will feel unpleasant and lethargic instead of being alert. Hygiene is also very important for good health. A large number of bacteria keep sticking to our bodies and clothes.

Essay on Mobility of Heavy Metals in Different Soils

Ecosystem
Metals whose densities exceed 6 g cm are usually referred to as heavy metals. Some (Co, Cr, Cu, Fe, Mn, Mo, Sn, V, W, Zn) of these are essential for life processes whereas others (Cd, Pb, Hg) have no known useful biologi­cal role; all of them are injurious to living organisms at higher concentrations.Davies et al. (1987) have studied the relationships between leaf and soil concentrations of Cd, Cu, Pb and Zn, using radish (Raphanus sativus) as the experimental plant which was grown on 46 garden soils. These soils were characterized by varying degrees of metal contamination. In some pots of contaminated soil, they added lime to modify soil pH.Liming was found to greatly reduce foliar Zn concentrations. The pH effect appears to be exercised through a modification of the…
