Nowadays, environmental problems have caused a lot of concern. Some people argue that those problems are too much to be handled by individual people or a single government and it should be an international concern. I think making environmental problems an international responsibility is necessary. People on the earth shared the same planet thus they also shared pollution, especially air and water pollution. Air is always moving from one area to another, bring the pollution with it. Air pollution can cause damage especially to human lungs. Greenhouse gasses from any place can cause global warming and it is the most significant cause of ice melting in the northern area. Consequently, some areas near the beach and small islands might sink due to the increasing ocean water level. If Indonesia, a country with the biggest number of small islands, does everything it can to reduce greenhouse gas production, but other countries keep releasing greenhouse gasses to the air. Sooner or later, some island in Indonesia will sink. The earth also shared water pollution in the ocean, such as garbage. Garbage in the ocean can kill marine lives. More and more fish, birds and other animals were found with garbage in their belly. There is a village in Japan that declares themselves zero waste and Japan's government is supporting zero waste movement. However, their oceans still have garbage from people from other countries. People in the world must stop throwing waste into the river and the ocean, for the ocean to be cleared from garbage.In conclusion, people in the world and all countries have a responsibility to protect the environment. There should be a limited number of pollution and garbage that a country can produce. To achieve that, the government should bring more awareness, educate and control their industry and citizens to reduce environmental damage. If the international community works together for the environment, it can reduce the damage from environmental problems.
