Environmental blight is a major cause for concern throughout the industrialised world. As industry grows, so does pollution. Among most victims of this equation are the waterways and lakes of the world. For it has become clear that water is no longer a mere drink -- water has become a raw material indispensable to every advanced economy. It is also a raw material that is used over and over again. The problem facing industrialists, as well as ordinary households, is how to exploit water without ruining its natural state. At the moment, river and lake pollution is increasing at an alarming rate, fish are dying of lack of oxygen, and once proud rivers have become horrible to look at. Surface pollution can become so thick, that the Cuyahoga river in Ohio literally caught fire in 1970.
Much research is underway to solve the problem of industrial pollution, based mainly on the introduction of purification systems into industrial and sewage outflow. And many organisations, including the United Nations, NATO, the E.E.C., have instituted research projects into the problem. This production illustrates the problem and shows some of the methods currently in use to combat it.
SYNOPSIS: Industrial waste pours into the river wherever factories are. But industry doesn't carry all the blame for the pollution that is ruining the industrial world. Peas are washed, so is beef, and the water used all finds its way back to where it came from - the rivers. As industry grows and sink and sewage water continues to be pumped back into the rivers and seas....pollution grows. Even the most house-proud flat dweller contributes his share of chemicals and detergents.
One thing has become clear -- water is no longer a mere drink....it is a raw material indispensable to every advanced economy. Water is used again and again...and it pollutes easily. Smoke belches for the from chimneys, polluting the air, and dirtying the water. The problem facing industrialists, as well as the ordinary citizen, is how to exploit water without ruining its natural state.
Pollutants such as chemicals from industry, household detergents and waste harm the water, and reduce its capacity to take in oxygen. We don't suffer directly from this, fish do... In polluted rivers and lakes, fish are the first to suffer. Here they're gasping for air as the river water can no longer fulfil its natural task.
Thick surface pollution forms, and the health of everybody is endangered by the bacteria that feeds on it Environmental pollution has become one of the major preoccupations of our time....and research projects into overcoming it have been started by the United Nations, NATO, the EEC and a host of private foundations. Many factories have made a serious attempt. Here, before entering the river, the industrial waste goes through a purification process. Special settling tanks have been provided, in which solid matter is first deposited. This takes out some of the chemicals.
Later, more sophisticated plants use bacteria to convert the remaining organic materials into inorganic. This helps, but still disrupts the cycle of the river - the purified water is often too rich.
It seems that whatever is done, an industrial society must create a certain amount of pollution. And the first victim are the major waterways, along which the large factories are. Research continues, but in the meantime, the environment suffers.
