Psychology Ecological Wellbeing Discussion

I’m working on a psychology discussion question and need an explanation and answer to help me learn.

Reading the following: At present rates, the population of the 51 countries in sub-Saharan Africa is expected to more than double by 2050, and by that time, in spite of decreasing birth rates in the developed countries, the world’s population will have increased from 7.2 billion (at the time of this writing) to 9.7 billion. We can see that doubling a population will double its impact if affluence and technology remain constant; it is likely that this is what will happen in the countries in sub-Saharan Africa over the next three decades. One can also see how it is the case that the 20% of people living in the affluent, high-tech, industrialized world are actually having a much bigger ecological impact than the 80% living in the developing world.

How do you feel after reading this piece of information? Please give some strategies for change and an affirmative way forward to a desired future but without being naive or in denial about where we are and why.
