On this front too, there is a pressing moral need for renewed solidarity, especially in relationships between developing countries and those that are highly industrialized. The technologically advanced societies can and must lower their domestic energy consumption, either through an evolution in manufacturing methods or through greater ecological sensitivity among their citizens. It should be added that at present it is possible to achieve improved energy efficiency while at the same time encouraging research into alternative forms of energy. What is also needed, though, is a worldwide redistribution of energy resources, so that countries lacking those resources can have access to them. The fate of those countries cannot be left in the hands of whoever is first to claim the spoils, or whoever is able to prevail over the rest. Here we are dealing with major issues; if they are to be faced adequately, then everyone must responsibly recognize the impact they will have on future generations, particularly on the many young people in the poorer nations, who “ask to assume their active part in the construction of a better world”.
50. This responsibility is a global one, for it is concerned not just with energy but with the whole of creation, which must not be bequeathed to future generations depleted of its resources. Human beings legitimately exercise a responsible stewardship over nature, in order to protect it, to enjoy its fruits and to cultivate it in new ways, with the assistance of advanced technologies, so that it can worthily accommodate and feed the world's population. On this earth there is room for everyone: here the entire human family must find the resources to live with dignity, through the help of nature itself — God's gift to his children — and through hard work and creativity. At the same time we must recognize our grave duty to hand the earth on to future generations in such a condition that they too can worthily inhabit it and continue to cultivate it. This means being committed to making joint decisions “after pondering responsibly the road to be taken, decisions aimed at strengthening that covenant between human beings and the environment, which should mirror the creative love of God, from whom we come and towards whom we are journeying”.
Let us hope that the international community and individual governments will succeed in countering harmful ways of treating the environment. It is likewise incumbent upon the competent authorities to make every effort to ensure that the economic and social costs of using up shared environmental resources are recognized with transparency and fully borne by those who incur them, not by other peoples or future generations: the protection of the environment, of resources and of the climate obliges all international leaders to act jointly and to show a readiness to work in good faith, respecting the law and promoting solidarity with the weakest regions of the planet. One of the greatest challenges facing the economy is to achieve the most efficient use — not abuse — of natural resources, based on a realization that the notion of “efficiency” is not value-free.
