Many people believe that the increasing number of cars in cities is the biggest source of pollution and waste. Others think that industries are the ones causing pollution.

Environmental
pollution
is currently the biggest challenge facing the world today. A staggering increase in the number of cars all over the world is believed to be the main culprit as opposed to others who reckon that a substantial contribution to the
cause
of
pollution
is made by industries. Through the
first
lens, the growing demand for using cars in urban areas directly gives rise to air
pollution
. The fumes from cars’ exhaust comprise dangerous gases which
cause
environmental problems as they spread. Vehicle emissions result in increasing the level of carbon dioxide and other greenhouse gases in the atmosphere.
Hence
, these gases trap the sun’s heat in the atmosphere leading to an increase in the temperature of the earth. Many scientists reckon that burning fossil fuels
such
as gasoline contribute to a high level of greenhouse gases, leading to global warming.
Besides
, the other contamination could be excessive car noise resulting from road traffic. Air
pollution
can be harmful to human as it is a major
cause
not only of hearing loss, but
also
of heart disease, learning problems in children and sleep disturbance.
On the other hand
, most of the contaminants stem from industries, which is the rampant
cause
of
pollution
worldwide. Discharging various industrial waste products into
water
bodies results in
water
, soil and air
pollution
. Industrial waste is one of the main causes of
water
pollution
, which is dumped directly into oceans and seas.
Water
pollution
is a serious threat to humans, animals, and aquatic life. By far the biggest consequence of
water
pollution
is the death of aquatic creatures, which can disrupt the entire food chain. To sum up,
although
cars and Industries both are the main factors in contributing to
pollution
, in my opinion, humans are more prone to toxic
water
and degrading
water
quality with dumping industrial waste is the main culprit.
