In his speech this morning to the U.N. General Assembly, Pope Francis called on world leaders to pay more attention to the condition of humankind and to the environment, which he considers inseparable. So much so, he said, that “Any harm done to the environment, therefore, is harm done to humanity.”

Francis noted that humans are violating a fundamental “right of the environment,” and he said science offers solutions. He also implored the world to end human trafficking, stop the drug trade and reduce the likelihood of nuclear war. 

The pope did not say that rising population is a problem, indicating instead—during his U.N. speech as well as one to Congress yesterday—that abuse of power, wanton consumption of natural resources and disregard for the poor are the bigger threats to human existence on Earth.

Here are portions of what Francis said about the environment as well as science, which embellished quite a bit on the transcript released before his address.

Today’s world presents us with many false rights, and…broad sectors which are victims of power badly exercised: for example, the natural environment and the vast ranks of the excluded. These sectors are closely interconnected and made increasingly fragile by dominant political and economic relationships. That is why their rights must be forcefully affirmed, by working to protect the environment and by putting an end to exclusion.

First, it must be stated that a true “right of the environment” does exist, for two reasons. First, because we human beings are part of the environment. We live in communion with it, since the environment itself entails ethical limits which human activity must acknowledge and respect. Man, for all his remarkable gifts, which “are signs of a uniqueness which transcends the spheres of physics and biology” (Laudato Si’, 81), is at the same time a part of these spheres. He possesses a body shaped by physical, chemical and biological elements, and can only survive and develop if the ecological environment is favorable. Any harm done to the environment, therefore, is harm done to humanity.

Second, because every creature, particularly a living creature, has an intrinsic value, in its existence, its life, its beauty and its interdependence with other creatures. We Christians, together with the other monotheistic religions, believe that the universe is the fruit of a loving decision by the Creator, who permits man respectfully to use creation for the good of his fellow men and for the glory of the Creator; he is not authorized to abuse it, much less to destroy it. In all religions, the environment is a fundamental good (cf. ibid.).

The misuse and destruction of the environment are also accompanied by a relentless process of exclusion. In effect, a selfish and boundless thirst for power and material prosperity leads both to the misuse of available natural resources and to the exclusion of the weak and disadvantaged…. Economic and social exclusion is a complete denial of human fraternity and a grave offense against human rights and the environment. The poorest are those who suffer most from such offenses…. They are part of today’s widespread and quietly growing “culture of waste”….

The adoption of the 2030 Agenda for Sustainable Development at the World Summit, which opens today, is an important sign of hope. I am similarly confident that the Paris Conference on Climatic Change will secure fundamental and effective agreements. Solemn commitments, however, are not enough, even though they are a necessary step toward solutions.… Our world demands of all government leaders a will which is effective, practical and constant, concrete steps and immediate measures for preserving and improving the natural environment and thus putting an end as quickly as possible to the phenomenon of social and economic exclusion….

The ecological crisis, and the large-scale destruction of biodiversity, can threaten the very existence of the human species. The baneful consequences of an irresponsible mismanagement of the global economy, guided only by ambition for wealth and power, must serve as a summons to a forthright reflection on man…. Creation is compromised “where we ourselves have the final word… The misuse of creation begins when we no longer recognize any instance above ourselves, when we see nothing else but ourselves.” (ID. Address to the Clergy of the Diocese of Bolzano-Bressanone, 6 August 2008, cited ibid.) Consequently, the defense of the environment and the fight against exclusion demand that we recognize a moral law written into human nature itself….

I began this speech recalling the visits of my predecessors. I would hope that my words will be taken above all as a continuation of the final words of the address of Pope Paul VI; although spoken almost exactly 50 years ago, they remain ever timely. “The hour has come when a pause, a moment of recollection, reflection, even of prayer, is absolutely needed so that we may think back over our common origin, our history, our common destiny. The appeal to the moral conscience of man has never been as necessary as it is today… For the danger comes neither from progress nor from science; if these are used well, they can help to solve a great number of the serious problems besetting mankind (Address to the United Nations Organization, 4 October 1965).” Among other things, human genius, well applied, will surely help to meet the grave challenges of ecological deterioration and of exclusion….
