This is true about the poor as it is with the earth. We have lost the ability to be aware of “the signs of the times”. The fact is that the increase in natural disasters should give us the pause to recognize that the earth is convalescing from the illness of our pollution and these natural disasters occur as it attempts to find balance (much like the fevers we experience when our antibodies are activated). The poor of course will have fewer resources to address these major ecological shifts and this too is something that will reach the ears of the Almighty.
The commitment that Pope Francis wants us to make is for a change of lifestyle that will respond to the needs of the poor and the needs of the earth. Part of this is a call to embrace a simple Christian lifestyle with concrete expressions such as the ones offered here.
