Question

Everyday on radio, on TV, and in the newspaper, we hear, see or read about many problems in the world, for example, pollution problems. Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars, airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped anywhere, even in the city where many people are living. The second pollution problem is sea pollution. Many people earn their living from fishing in the sea, and the fish they catch feed many people. But the sea has become so polluted from oil spills and factory wastes that the fish are dying. This is not only killing the fish, but is also affecting those people who eat fish. Seldom do you find a place nowadays that is not polluted. This problem is growing more difficult every day. We must find a good solution that makes the world a better place to live.

Answer 1

This Passage is all about pollution and what we have to do for better live in the world.

What is Pollution?

The introduction of toxins into the environment that have a negative impact on it is known as pollution. Pollution can be any kind of material or energy. Both naturally occurring contaminants and imported substances/energies can be considered pollutants, which are the elements of pollution.

A single significant environmental emitter is referred to as a point source. This typically indicates that a source may be located, such as a manufacturing drainpipe or the smokestack of a coal-fired power station.

Non-point sources, on the other hand, are challenging or even impossible to identify since their pollutants are scattered. An illustration would be the runoff of pesticides and fertilizers from lawns on golf courses, farms, and homes into lakes or streams. Although the presence of pollution in the streams and lakes is obvious, its exact source is not always clear.
