Humankind, which discovers its capacity to transform and in a certain sense create the world through its own work, forgets that this is always based on God's prior and original gift of things that are. People think that they can make arbitrary use of the earth, subjecting it without restraint to their wills, as though the earth did not have its own requisites and a prior God-given purpose, which human beings can indeed develop but must not betray.

Unfortunately, it is now clear that the application of these discoveries in the fields of industry and agriculture have produced harmful long-term effects.

When you wonder about the mystery of yourself, look to Christ, who gives you the meaning of life. When you wonder what it means to be a mature person, look to Christ, who is the fulfillness of humanity. And when you wonder about your role in the future of the world look to Christ.
