Answer:
Easy access to medical care is not a reason for high birth and death rates in developing countries.
Explanation:
A big portion of the developing countries tends to have high birthrates and high death rates. The reason for this are numerous, ranging from political, religious, traditional, economic, low education levels, women being discriminated against, etc. In general, it seems that the lower the status of women is in a society, the higher the birthrates are, and all of the factors that contribute to it actually result in a shorter life span for the whole population.
One thing that doesn't contribute to this is easy access to medical care. Easy access to medical care is not something that is found in a developing country, on contrary, the access to medical care is hard, limited, and for many people out of reach. When medical care is not available for the population the results are always devastating, with high death rates among infants, during birth (both mothers and children), diseases spread very easily and have a much bigger impact, and because of lack of it also the population leaves shorter lives.
Answer and Explanation: Earth's climate has changed dramatically many times since the planet was formed 4.5 billion years ago. These changes have been triggered by the changing configuration of continents and oceans, changes in the Sun's intensity, variations in the orbit of Earth, and volcanic eruptions. Hope it helps!
