Based on the universal law “Polluter pays”, effect to restore the ecology and safeguard the human health with people's participation has taken place in Daurala near Meerut. These efforts are now bearing fruits after a span of three years when Meerut based NGO had developed a model for ecological restoration. The meeting of the Daurala Industries officials, NGOs, Government officials and other stackholders at Meerut has brought out results. The powerful logics, authentic studies and the pressure of people have brought a new lease of life to the twelve thousand residents of this village. It was in the year 2003 that the pitiable condition of Dauralaities drew the attention of the civil society. The groundwater of this village was contaminated with heavy metals. The reason was that the untreated waste water of Daurala industries was leaching to the groundwater table. The NGO conducted a door to door survey of the health status of the residents and came out with a report. The organisation, the village community and people's representatives sat together to find out sustainable solutions to the health problem. The industrialists showed a keen interest towards checking the deteriorating ecology. The overhead water tank's capacity in the village was enhanced and a 900m extra pipeline was laid to supply potable water to the community. The silted pond of the village was cleaned and recharged by distilling it. Large quantity of silt was removed paving way to large quantity of water so that it recharged the aquifers. Rainwater harvesting structures have been constructed at different places which has helped in diluting the contaminants of the groundwater after the monsoons. 1000 trees have also been planted which improved the environment.

Vanaja and vasula are twin sisters who hail from the state of Kerala. They observed that children from her village were suffering from deformities due to prolonged use of pesticide contaminated river water and endosulphine spayed fruits and vegetables.

In the beginning, the firm would be an association of two persons who would carry on the business as co-owners, would share profits and losses and would have unlimited liability. In order to avoid conflicts in future they would have a written agreement which will include all the classes relating to authority and responsibility of members, voting rights and roles and payment of members. The sisters will act as principal and agent for each other and for the firm. They discussed this proposal with the Block Development Officer (BDO).

Read the given passage carefully and answer the following question :
Depending on the mode of occurence and the nature of the ore, mining is of two types : surface and underground mining. The surface mining is also known as open-cast mining is the easiest and the cheapest way of mining minerals that occur close to the surface. Overhead costs such as safety precaution and equipment is relatively low in this method. The output is both large and rapid.
When the ore lies deep below the surface, underground mining method (shaft method) has to be used. In this method, vertical shafts have to be sunk, from where underground galleries radiate to reach the minerals. Minerals are extracted and transported to the surface through these passages. It requires specially designed lifts, drills, haulage vehicles, ventilation system for safety and efficient movement of people and material. This method is risky. Poisonous gases, fires, floods and caving in lead to fatal accidents.
The developed economies are retreating from mining, processing and refining stages of production due to high labour costs, while the developing countries with large labour force and striving for higher standard of living are becoming more important. Several countries of Africa and few of south America and Asia have over fifty per cent of the earnings from minerals alone.
