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.
Mantle I think that is it!

Answer: Water pollution can have disastrous effects on the environment.
Explanation:
- Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe. The fish can suffocate and not have enough air.
- Pollution affects the entire food chain. Small fishes absorb pollutants, such as chemicals, into their bodies. Bigger fishes eat the smaller fishes and get the pollutants as well. Birds or other animals may eat the bigger fishes and be harmed by the pollutants. One example of this was the use of the insecticide (bug killer) DDT, which is when birds of prey ate fishes that were infected with it, they would lay eggs with thin shells. The population of birds of prey began to drop until DDT was banished.
- Sewage causes major problems in rivers. Bacteria in the water will use oxygen to break down the sewage. If there is too much sewage, the bacteria could use up oxygen until there won't be enough left for the fish.
- Water pollution from major events like acid rain or oil spills can completely destroy marine habitats.
- One of the most important commodities for life on planet Earth is clean water. For over 1 billion people on the planet, clean water is nearly impossible to get. Dirty, polluted water can make them sick enough to die.
