Pollution is when we put something into the environment, whether intentionally or not, that is harmful or poisonous to others. We are not really aware of the effects of pollution in the world and how we contribute to it.
During this season of Lent, we are invited to enter our own deserts, to reflect on ourselves and on our sinfulness. We do this not by looking only at our own persons, as in a vacuum, but by examining our relations with others—other people, other creatures, our environment, with God. We are invited to assess our accountability for negatively affecting the environment and the people around us, especially the poisoned poor.
