Nowadays it is more important to plant trees in open spaces in towns and cities than building houses. To what extent do you agree or disagree.

In the modern days, many

people

think that plants are believed to be more crucial to be grown in the open spaces in towns or cities than in concrete buildings. Personally, I argue that big

trees

should be planted outside buildings while some medium-small flora can be put inside constructions.

To begin

with, there are two main reasons why big greens should be planted in open-

air

areas.

Firstly

, when being put outside, greenery with large sizes can purify polluted

air

which is mainly exhausted into the atmosphere by factories and vehicles.

For example

, in Singapore where a large scale of woods has been grown in

streets

, the

air

pollution rate is very low.

Secondly

, big greens release a great deal of oxygen, they

also

exhaust a large amount of carbon dioxide which is

also

known as CO2 at night when there is a shortage of sunlight. When being planted inside, those emissions can cause difficulty in breathing whenever the

trees

increase their respiratory activities. To abridge, woods should be grown outside of the building because of their

air

clarifying and producing CO2 abilities.

In contrast

, medium-small

trees

should be put inside the buildings for two main factors.

First

and foremost, little greenery can make

people

who live and work inside the towers happy. To be specific, many big companies, namely Facebook and Google, always create green areas for their employees; when being asked for the reasons, they claimed that it made the workers more productive.

In addition

, small

trees

planted with appropriate numbers can be seen as decorations.

For example

, many interior designs have used tiny pots of spice

trees

or medium flower pots as beautifying furniture.To conclude, only medium-small plants should be grown inside houses for keeping up

people

's moods and decorating. In conclusion, big

trees

should be planted in open areas in order to clear the

air

and avoid affecting

people

's breathing at night while small

trees

should be grown inside for satisfying and accessorizing purposes.
