Many countries are experiencing population growth and need more homes. Should these new homes be constructed in existing cities or should new towns be built in the countryside?

I think new homes should be constructed in existing cities. As

this

would be more cost efficient for the

government

. In the cities, basic infrastructures are already there, like the water pipes, electronic pipes and networking sites, etc.

however

Suggestion

However

, in the countryside, there is no or even lack of these infrastructures, if the

government

build

Suggestion

builds

new towns there, it's not just involve building homes, but

also

clinics, fire station, transportation, malls, and all kinds of basic infrastructures, which can cost a lot to the

government

, while it may not be effective in adding more homes for people. It is more cost effective and as well faster to build housing in cities, which homes are closer to different facilities and workplace.

Secondly

, building new towns in the countryside can cause damage to the mother nature. Once towns are built in those green areas, it can never be reversed. It isn't just causing damage to the plants, but

also

the animals and their habitats. Trees and plants can help refresh the environment, which may possibly slow down the climate change. Destroying them is same as destroying out living planet. Some people may say that the population density of the cities is very serious, building homes in cities may make it denser, homes may become smaller.

However

, there are actually lots of lands that are not well used or not used in cities, it is high time that the

government

can make better

land

use planning to build housing. In

this

way, not just can lessen the financial burden of the

government

on unnecessary

land

use,

for instance

, some barren

land

or golf

land

, but can

also

build more housing.
