Changing Population Trends Section 2 Quiz

The 1991 cholera outbreak in Lima, Peru was caused by a lack of clean water. Cholera is a waterborne disease that spreads through contaminated water or food. In this case, the outbreak occurred because the water supply in Lima was contaminated, leading to the spread of the bacteria that causes cholera. The inadequate sanitation and lack of access to clean water allowed the disease to thrive and affect a large number of people. The other options, such as inadequate medical care, widespread malnutrition, and rats and other rodents, may contribute to the severity of the outbreak but are not the primary cause.

Asia is currently experiencing the fastest-growing populations. This can be attributed to various factors such as high birth rates, improving healthcare systems, and increasing life expectancy. Additionally, Asia has a large land area and diverse countries, each with its own unique population growth patterns. With its booming economies and urbanization, Asia has become an attractive destination for people seeking better opportunities and a higher standard of living. Therefore, it is not surprising that Asia is leading in terms of population growth compared to other continents.

Legal punishments may not be an effective strategy to slow population growth because they do not directly address the underlying causes of population growth. While legal punishments may deter individuals from engaging in certain behaviors, they do not address the root causes such as lack of access to contraception, education, or economic opportunities. Additionally, legal punishments may have unintended consequences such as increased rates of unsafe abortions or underground activities. Therefore, while legal punishments may have some impact, they are not a comprehensive or sustainable strategy to slow population growth.

The given answer suggests that Earth's population will stabilize around 9 billion by 2050. This is based on the information provided in the question that birth rates have begun to fall. As birth rates decrease, it implies that the population growth will slow down and eventually stabilize. However, since the question does not provide specific data or trends, it is impossible to determine the exact population level. The answer is an estimation based on the assumption that birth rates will continue to decline.

The answer states that many people have low literacy and limited access to healthcare, which makes it difficult to reduce population growth. This is because low literacy rates often lead to a lack of knowledge about family planning methods and limited access to healthcare means that people may not have access to contraceptives or reproductive health services. These factors can contribute to higher birth rates and a lack of control over population growth.
