d. The Destruction of Ecosystem

Environmental pollution

is one of the impacts of human activities on the
Earth. It is also one of the biggest problems of the world today because it
brings about contamination, ecosystem, and the cause of some diseases that
most people do not know about. There are four types of pollution, namely,
air pollution,air
soilpollution
pollution, water pollution and noise pollution.
Most of the
results from the burning of fossil fuels, motor
vehicles, factories, aircraft and rockets. This can cause acid rain which
damages water, soil, and vegetation. Air pollution also contributes to the
greenhouse effect which can lead to a series of environmental problems such
pollution
as Soil
global
warming, polar ice melting, rise of sea levels and loss of land.
is a result of dumping plastic or other inorganic waste in the
ground and the overuse of chemical fertilizers in agriculture. The long-term
effects of soil pollution are contaminated vegetation and the decrease of soil
fertility.

Water pollution is a result of dumping pollutants such as
detergents, pesticides, oil, and other chemicals in rivers, which makes the
water unclean or contaminated. Rubbish blockages in rivers can also
cause pollution.
The effects of water pollution include the destruction of ecosystem of
rivers, lakes and the pollution of groundwater, surface water and seawater.
Noise pollutionis caused by loud and annoying sounds of motor
vehicles, railway, aircraft and jet engines, factory machinery and musical
instruments. It can cause stress and psychological and health problems for
humans
such as increased
Environmental
pollution heart rate and hearing damage.
is becoming an increasingly serious problem or
threat that needs to be taken care of as soon as possible, not only for the
sake of the envionment, but also for the people that live in it.
