In order for a country to ensure sustainable development, multiple strategies should be adopted that should improve the human life. The development should have no long-term harmful and negative effect on the environment as it is essential to preserve the environment while continuously developing. Moreover, the responsibility of this development is equally of both the leaders as well as the citizens. But in no case, it is possible to ensure sustainable development if no money is spent. The money spending is necessary for the growth. However, it should be properly planned and should not drain the economic health of the country.
Hence, the correct answer is 'it should cost no money at all for better economic health'.
