137 Mutual assistance between countries proves enriching for each. A country that moves forward while remaining solidly grounded in its original cultural substratum is a treasure for the whole of humanity. We need to develop the awareness that nowadays we are either all saved together or no one is saved. Poverty, decadence and suffering in one part of the earth are a silent breeding ground for problems that will end up affecting the entire planet. If we are troubled by the extinction of certain species, we should be all the more troubled that in some parts of our world individuals or peoples are prevented from developing their potential and beauty by poverty or other structural limitations. In the end, this will impoverish us all.
