birth and death
today i was reading on wikipedia that every year about 137 million people are born, but only about 56 million die. both birth and death rates have dropped significantly in the last few decades, but the birth rate is still a lot higher. world population is expected to cross nine billion in the year 2040. when i was a senior in high school in 1974, there were about four billion people on earth.
