d. Industrialization
Many industries and factories are established with the
increase of industrialization. Industries and factories
produce excessive amount of dust, ash and smoke
containing harmful gases. They randomly discharge
solid wastes here and there in the surroundings.
Above all, the liquid discharges from industries and
factories are directly mixed into water resources.
Ultimately, there is increase of air, water and land
pollution as well as serious impact on terrestrial and Fig: 12
aquatic ecosystems. Industrialization

e. Wars and explosions
The tussle between different
nations increases conflicts
and sometimes wars. During
wars, many deadly weapons,
guns, rifles, bombs, etc. are
used. They cause production
of smoke, dust and harmful
gases as well as intense
sound. Even sometimes, Fig: 13
some nations keep on testing Civil war Bomb explosion
missiles, nuclear and atomic
weapons. They increase intense sound, smoke, harmful radiation, etc. These all seriously
affect human life and other living beings in environment.

f. Unmanaged urbanization
Unmanaged urbanization has caused unplanned
extension of settlement areas. There is random increase
of deforestation, scarcity of drinking water, problem
of solid waste management, drainage, electricity,
proper roads, etc. In the one hand, those problems
have seriously affected human life and in the other
hand, various types of pollution are increased in the
environment. Fig: 14
