One of the most important aspects to take into consideration regarding the subject in question is that soon enough there will not be enough food for all inhabitants of the planet. That is the reason why it is significant to completely change our approach to farming as well as the way we consume food. What it means is that we need to learn how to waste less food.
What should also be taken into account is the issue of housing. Affordable housing. There will be more people on the planet and they all need to live somewhere. Besides, they need to be able to pay for that apartment or house and have enough money to live on.
Surely, there should be enough educational institutions for people to get their degree as the more intelligent mankind gets, the more likely we are going to drive positive change. What it means is that we will be able to tackle more issues and solve more problems in such a way. The key point is to deal with population increase in a way that works perfectly for everyone.
