Illegal and indiscriminate river sand mining is going to cause a large number of environmental and social problems in World. By Dr. Nitish Priyadarshi Geologist.  This is Kanchi river which provides sands to Ranchi district.   This is Jumar River near Ranchi which now contains less sand deposit due to over exploitation. Illegal sand mining is a scourge in states across India. The latest battle in Gautum Buddh Nagar, Uttar Pradesh, where sub divisional magistrate (SDM) was suspended from service, has served to highlight the plight of rivers ravaged. Construction work on projects worth thousands of crores of rupees in Jharkhand has been affected by a sand crisis caused by the on-again, off-again auction policy.

Most of the water on this planet is stored in oceans and ice caps which is difficult to be recovered for our diverse needs.

Not only there is an increasing concern for rapidly deteriorating supply of water but the quantity of utilizable water is also fast diminishing. The causes of such a situation may be many, but gross pollution of water has its origin mainly in urbanizati...

Stories about water serpents have slithered into many cultures. But what about the science of sea monsters? In fact, there was a time when they did exist. About 250 million years ago Earth’s continents were gathered into one landmass, Pangaea. Shallow seas and the lack of significant marine predators created new niches for many reptiles that had developed on land. They wri...
