"What's Your Number?" Reflection

     A 1000 years ago, the world's population started out with 0. 3 billion. Since then, the population grew dramatically to 7.0 billion and is still growing. When the population was at 0. 3 billion, I learned that the birth rate and death rate helped balance the population because of infant mortality. But, eventually as time passed, we developed a better agriculture and developed better medicines that helps people to live longer, causing an increase in the population. Another factor was that women were starting to have more babies. I also learned that there are other factors that could change the population number: migration, aging, diseases, and life expectancy. I was the 5,935,993,664th person alive on Earth and 81,399,754,170th people where before me. 
     My thoughts on population is that we are growing at a fast pace. I do believe we have a lot of people, but I have never really looked at it as a bad thing. But after learning more about population, it makes me wonder. What I am worried about is how much of the earth's capacity we are using up. Fearing that in the future, we start develop higher technologies and producing more chemicals that are used for our food would eventually start hurting our health and the environment even more.
