God entrusted the earth into our care (Gen 1:28). Care for our common home includes fighting global warming or climate change. Our wasteful way of living has an important impact on the environment. Is it really fair that less than a quarter of the population of the world consumes 80% of the global resources? The principle of solidarity urges us to strive for a better global distribution of the richness of the earth. After all, it has been given by God to all humanity.
Prophets of doom say that we need to look for another planet if humanity is to survive. This is the worst expression of a ‘waste culture’. A better answer would be to see how God is always waiting for us to turn around (Lk 15:20) and implore his help, while doing what we can to preserve the earth.
