Basically climate change is a global issue. The Prime Minister attended an important conference in Saudi Arabia regarding the issue. The changed rain patterns, food security, melting of glaciers and water scarcity are major threats caused due to climate change. There is a dire need to preserve water. The government should initiate construction of small and large dams in order to avoid flooding and store water. There are certain measures already taken in this regard. Rain harvesting system is introduced. The common man can also play a role in storing water. There must be a ban on washing cars in homes. The government must also launch a comprehensive campaign to generate awareness among the people on the advantages of not wasting the water.
