Conflict of Business, Development, Sand, Flood and Wildlife

Many do not know that wildlife can be a good indicator for environment health and care taker for environmental equilibrium. We need to understand them well. Understand their habitat, population, composition, behaviour and human interaction.
For human benefit we need development, house, space, jobs and comfortable environment to live. BUT we cannot allow the greedy business people to dictate our needs for their profit.There is no detail studies on the effect of sand mining on wildlife habitat. The only active studies were on how to extract sand from rivers effectively.
