Developed countries have created many environmental problems in the world, particularly in thier contribution to global warming. Why is global warming a problem? What can be done to reduce the dangers of global warming?

In contemporary society, There are many vital problems that humans must face , especially global warming,

this

essay will discuss the detail that why global warming become a serious

problem

and the suggestion from my opinion.

First

of all, Global warming is the

phenomenon

that makes our earth become hotter or has more disasters.

This

problem

occurs through human activities ,

for instance

, cutting

trees

down, releasing chloro-fluorocarbon gas into the environment or air,

this

gas will gather together and become a layer in the atmosphere of our world,

this

action will not allow the energy, like heat, to pass through, it's called "greenhouse effect".

Moreover

,

this

phenomenon

will affect many parts of the world, the melting ice in the north pole, and the extinction of some species because of the overheating temperature.

On the other hand

, many researchers tell us that the solution to

this

problem

will take a very long time. Meanwhile, we must not harm the environment much more than in the past.

However

, there are many effective ways to help our world,

for example

, using the 5-R principle, including "reuse", "reduce", "repair", "recycle", and "repurpose". Planting new

trees

is

also

a way to help too because

trees

can change the carbon dioxide, which is the factor that helps chloro-fluorocarbon gather, into oxygen, the gas that humans use in the respiratory system. To summarize, global warming is a

phenomenon

that occurred through human activities, so humans must be contributing to reducing the dangers of

this

phenomenon

by ourselves, planting more

trees

or reducing to use of more plastic is the most effective way to solve

this

problem

. What is your opinion about

this

problem

?
