In many cities around the world pollution levels have risen in recent years. Why are some cities becoming more polluted? What effects does this have?

In a large number of cities worldwide,

pollution

levels have been on the rise in recent years.

This

is mainly caused by the development of industrial sectors and the rising number of vehicles.

This

phenomenon leads to negative environmental effects and various diseases threatening living beings. The advancement of technology, especially in transportation and factories, is accountable for causing

pollution

. In fact, many firms produce most of

pollutants

the pollutants

show examples

in the city.

For example

, a charcoal factory in Serang is believed to be the greatest source of the famous grey smoke in Jakarta's sky.

This

smoke is blown by the wind and travels to Jakarta, causing dark fog, which is deteriorated by the presence of numerous vehicles in the city. Other than causing air

pollution

, many factories

also

throw the used liquid into

water

drainages and even rivers like what we have seen in the rivers in Jakarta. As everything has a price,

pollution

is evident to cause illness for humans, animals, and

plants

.

First,

air

pollution

is a threat to breathing problems

such

as cough, asthma, and lung cancer. It can be seen how China requires its citizens to wear masks outside to prevent them from inhaling harmful air.

Second,

water

pollution

can possibly harm

water

creatures and

plants

. The polluted

water

in the city rivers most likely contains chemical stuff, and if it is absorbed by the soil, on which the

plants

grow, gives a greater likelihood for the

plants

to dry out.

To sum up

,

pollution

has been a long discourse

that is

longing to be resolved. I opine that the government should set some rules to combat

this

problem. Some of these are to limit the use of transportation and make policies that manage

water

disposal.
