Explain the sustained growth in world population in the 20th century.
Answers
Answer:
Population growth is the increase in the number of individuals in a population. Global human population growth amounts to around 83 million annually,[2] or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.8 billion[3] in 2020. It is expected to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100.[4] Many nations with rapid population growth have low standards of living, whereas many nations with low rates of population growth have high standards of living.[5]
Answer:
Human population has grown exponentially over the past century. It has done so largely by producing large amounts of food, and learning how to control disease. During the 20th century, the global population saw its greatest increase in known history, rising from about 1.6 billion in 1900 to over 6 billion in 2000.
