By the development of modern civilization, ecosystem destruction and air/water/soil pollution are originated from human activity, and a lot of people still think that these are a global problem.

Due to the evolution of global society, a lot of hazardous substances, disposables, and even trash from various things or food are increased. Also, by the increase in population and progress in industry, global ecosystems are at risk.

Considering the damaging cases that occur in various parts of the world, holes are formed in the ozone layer and the earth gets warmer, thereby melting antarctic ice.


Antarctic glaciers will continue to melt and the sea level will rise. Therefore, an island like Tuvalu, Japan, and the United Kingdom is expected to sink under the water. And infectious diseases such as malaria, dysentery and encephalitis will seriously spread throughout the world.

For these reasons, citizens all across the world should take precautions as soon as possible. First of all, we should refrain ourselves from the use of hazardous substances and disposable products. And we should save resources and recycle after separating waste.

It is very important to practice these things at school more than anywhere else. Therefore, informing the minds to save and conserve our beautiful and precious environment will protect our Earth.
