The gradual depletion of the ozone layer and the related "greenhouse effect" has now reached crisis proportions as a consequence of industrial growth, massive urban concentrations and vastly increased energy needs. Industrial waste, the burning of fossil fuels, unrestricted deforestation, the use of certain types of herbicides, coolants and propellants: all of these are known to harm the atmosphere and environment.
Pope John Paul IIBelievers know that the presence of evil is always accompanied by the presence of good, by grace... Where evil grows, there the hope for good also grows... In the love that pours forth from the heart of Christ, we find hope for the future of the world. Christ has redeemed the world: "By his wounds we are healed." (Isaiah 53:5)

Pope John Paul IIYou made us for yourself, Lord, and our heart is restless until it rests in you. In this creative restlessness beats and pulsates what is most deeply human - the search for truth, the insatiable need for the good, hunger for freedom, nostalgia for the beautiful, and the voice of conscience.
Pope John Paul II
