Answer and Explanation:
1. Sub-Saharan Africa has a very strong economic dependency, which means that its population has less access to education and resources. The limitation of resources prevents the population from having full access to contraceptive methods that can limit the exacerbated growth of the population that did not have a structure that shelters it efficiently. In addition, deprivation of sex education has prevented families from learning concepts about contraceptive methods, family planning, among others that promote rational population growth. This all contributes to Sub-Saharan Africa's population growth, which is increasingly disproportionate and growing, compared to the rest of the world.
2. The two groups differ in their projections of population growth, because they make analyzes using different factors, at different intensities. This is because the projection of population growth is a subjunctive factor, which has countless variables and can have different analyzes and interpretations.

It is especially important to monitor tides for people who rely on the sea for living - fishermen have to know the kinds of tides they are going to experience so as to decide whether to set off in search of fish or not. It is also quite important to monitor tides if there is some construction going on near the shore - for example, building bridges or docks, as when the tide comes, it may flood the whole thing. Scientists also study the tidal movements so as to better understand the circulation of the oceans.
