  • Rapidly modernizing India

    • Industrial needs

    • Water needs


Pollution from Cities

  • Local industries dump toxic chemicals into the river

  • Sewage treatment plants dump raw sewage into the river


Problems:

  • nearly 1 billion liters per day - of mostly untreated raw sewage

  • Inadequate cremation procedures:

    • large number of partially burnt or unburnt corpses floating down the Ganga


Effects of Pollution:

Threats to Yangtze River

  • Pollution from industrial and agricultural discharges, along with sewage and ship waste:

    • Sewage and industrial waste dumping totalled 23.4 billion tons in 2001

many industrial enterprises established in 1960s-1970s have become the main sources of river pollution.


Effects of Pollution
