How do you say this in English (US)? It also suffers from high population density compared to the small land area. If the population of Korea doubled, the three big changes would be food and resource scarcity, environmental pollution, and a surge in homelessness.

Have you ever imagined what it would be like if Korea's population increased rather than decreased? Although Korea is a small country, it is a peninsula full of various cultures and patriotism. However, the current Korean society is rapidly changing into a low fertility society. It also suffers from high population density compared to the small land area. If the population of Korea doubled, the three big changes would be food and resource scarcity, environmental pollution, and a surge in homelessness.
One of the first major changes caused by population increase would be food and water shortages. Even now, Korea is a water-scarce country due to low rainfall. If the population doubles, water becomes scarce so we cannot water crops. When crops decrease, there is also less food that can be made. Then people will increasingly eat seafood from the sea. When the population grows, this can happen.
Another serious difference caused by a population increase would be environmental pollution. People will destroy forests to clear arable land because they need more food. Not only that, but the amount of waste will increase and the environmental pollution will become serious. Wouldn't it be very difficult to live in a place where many people had to live if it was polluted and destroyed like this? Even now, serious environmental pollution can get worse.
Finally, there are fewer places where people can live. The land area of our country is small, but if the population is large, the number of places where people can live decreases. Then house prices will rise and the number of tall buildings will increase. However, high-rise buildings have several risks like strong winds. Homelessness on the streets may increase due to the high cost of housing. If the population increases, the land area will not be able to handle it.
In conclusion, population growth can lead to food and water shortages, environmental pollution, and a surge in homelessness. Even if the population is large, not the low birth rate, there seems to be a disadvantage.
