Thermal pollution.

Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. Many industries use high temperature furnace and boilers in their manufacturing processes. The resulting hot effluents are directly released in to a nearby water source. This is called thermal pollution. It destroys the aquatic life due to the thermal shock. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature decreases oxygensupply and affects ecosystem composition. Urban runoff–stormwater discharged to surface waters from roads and parking lots–can also be a source of elevated water temperatures.

When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt change in water temperature known as "thermal shock."

जल का मरहम

भोर से निकला हुआ मुसाफ़िर,
बुझ कर जैसे बेहाल हुआ।
इस मुरझाये से चेहरे पे,
खुशियों का जो आकाल हुआ।
था हरियाली का साया जो,
वो न तो अबकी साल हुआ।
फसलें जो अब चौपट हुयी,
फिर किसान कंगाल हुआ।

अम्बर को निहारते रहते कि
तपता सूरज थक जायेगा।
नीला सा दिखता साया ये,
बादलों से फिर ढक जाएगा।

धरती हमसे अब ख़फ़ा हुयी,
जैसे हमसे कोई ख़ता हुयी।
आँसुओं से खेतों को सींचा,
नदियां जो अब लापता हुयी।
बारिश को तरसें हम बेबस,
पर बादलों की है आँख-मिचौली।
देकर खुशियों का ये झांसा,
लौटें लेकर अपनी टोली।

जो इंतेज़ार है सावन का,
जाने किस हद तक जाएगा!
धरती के आँचल में बादल,
जल का मरहम रख जाएगा।

Piku: Glad to know the actors of this flick.

Last time it was Madras Cafe (2013). This time it would be Piku. I am talking about the focus of praise. 

I mean I appreciate this man (Shoojit Sircar) for his choice of actors. I am glad to know that this time two great stars of film industry share the same stage - Amitabh Bachchan and Irrfan Khan. My expectations with this movie are high. Another reason being the direction of Mr. Sircar.
