“7. Article 48-A in Part IV (Directive Principles) brought by the Constitution 42nd Amendment Act, 1976, enjoins that "the State shall endeavour to protect and improve the environment and to safeguard the forests and wild life of the country". Article 47 further imposes the duty on the State to improve public health as its primary duty. Article 51-A(g) imposes "a fundamental duty" on every citizen of India to "protect and improve the natural environment including forests, lakes, rivers and wild life and to have compassion for living creatures". The word 'environment' is of broad spectrum which brings within its ambit "hygienic atmosphere and ecological balance". It is, therefore, not only the duty of the State but also the duty of every citizen to maintain hygienic environment. The State, in particular has duty in that behalf and to shed its extravagant unbridled sovereign power and to forge in its policy to maintain ecological balance and hygienic erwironment. Article 21 protects right to life as a fundamental right. Enjoyment of life and its attainment including their right to life with human dignity encompasses within its ambit, the protection and preservation of environment, ecological balance free from pollution of air and water, sanitation without which life cannot be enjoyed. Any contra acts or actions would cause environmental pollution. Environmental, ecological, air, water, pollution, etc. should be regarded as amounting to violation of Article 21. Therefore, hygienic environment is an integral facet of right to healthy life and it would be impossible to live with human dignity without a humane and healthy environment. Environmental protection, therefore, has now become a matter of grave concern for human existence. Promoting environmental protection implies maintenance of the environment as a whole comprising the man-made and the natural environment. Therefore, there is a constitutional imperative on the State Government and the municipalities, not only to ensure and safeguard proper environment but also an imperative duty to take adequate measures to promote, protect and improve both the man-made and the natural environment.”
