ConclusionDR

As it is now an issue, overpopulation is present. With our research, we concluded that with the birth and death rates present, overpopulation will present an even bigger threat. In China, for example, the population is 1.4 billion people and the birth rate is almost twice as much as the death rate. Furthermore, China's life expectancy high, taking third place in our life expectancy ranks with 75 years of age. With such a big population, and a high birth rate, every year the population would be increasing by about one fourth of its total population. Providing another example, although Macau has a small population, consisting of only 540,000 people, It has a birth rate that doubles its death rate. Macau the country with the highest life expectancy in the world, which means that many babies will be born increasing the population, and the small amount of deaths will not even out the country's growth. Out of all the countries from different continents and qualities of life, Swaziland is the only country in which is death rate is bigger than its death rate and presents the lowest life expectancy (32 years). However, this country presents a phenomenon due to their birth and death rates because it is also the country with the highest birth rate. The United States as well as, Brazil and South Africa also have a birth rate significantly larger than their death rates. The United States has the second highest life expectancy, and with its population of 303,000,000, it also means that this population is very quickly and significantly growing.
