Protecting environment is the responsibility of multi-national organizations rather than the responsibility of each government. Do you agree to disagree with this statement?

Environmental degradation is a prevalent issue in the modern world.  It is believed that environmental protection is the duty of international organisations rather than that of every government. I disagree with this view to a large extent as, in my opinion, environmental conservation is a matter of national and international importance, and is needed to be undertaken at the domestic and global levels.

Firstly, environmental issues are of international concern as these result in a cobweb of other critical problems. For example, widespread air pollution has resulted in global warming and climate change which have eradicated several plant and wildlife species, adversely affected the diverse ecosystems and imposed a grave survival crisis on mankind. Subsequently, multi-national bodies hold the obligation to implement environment preservation measures globally that prevent the spread of environmental problems worldwide.

Furthermore, harm to the environment results in harm to the society and the citizens of a country. Consequently, as the government’s duty is to protect its public, it must actively participate in safeguarding the environment in which its people live. For instance, in metropolitan cities such as New Delhi and Shanghai, the high pollution levels and massive deforestation have resulted in the spread of serious health issues, such as asthma and bronchitis. As a result, the local municipalities were made responsible for building nature parks and introducing clean drives and anti-pollution policies to not onlyalleviate this problem but also to preserve healthy living conditions.

•  safeguard 

Vt. 保护，保卫(某物)

e.g.: They will press for international action to safeguard the ozone layer.

•  deforestation 

n. 砍伐森林，毁林

e.g.: Deforestation can also change soil dynamics and increase erosion, both of which can release more carbon into the atmosphere.

•  the spread of 

…的蔓延/传播

e.g.: The greatest barriers to the spread of truly digital photography are price and quality. 

•  bronchitis 

n. [内科]支气管炎, [brɒŋ'kaɪtɪs]

e.g.: The most common of these in Western countries are bronchitis and emphysema (肺气肿), which are often caused by smoking.

•  municipality 

n. 市民，市

e.g.: The sprawling municipality has lots of land at its perimeter to devoce to the effort.

In conclusion, I do not agree that environmental protection is the sole responsibility of multi-national firms and instead, believe that both international organisations and individual governments are obligated to conserve the environment and nature in order to ensure a sustainable future.
