In today's overpopulation issues, it is always good to encourage those who want children to adopt and take care of those who are waiting to be with a family. People's issues affect everyone else in the world, directly or indirectly. When a farmer is sick, food production gets delayed; a road construction falls ill, road building will have one less worker to finish the job; when a husband beats his wife or children (and vice versa), their situation affects the neighbors and friends. When it comes to breeding one's own, however, it affects, not only other people's lives but everything on the planet (environment, wildlife, non-human animals, etc.) So the best way to take on other people's issues without adding population to the earth is to adopt children, adults, elderly, non-human animals AND educate people about the same.
