Population growth refers to the increase in the number of individuals in a population in a particular year. According to the United Nations Population Fund, human population grew from 1.6 billion to 6.1 billion people during the course of the 20th century. It took all of time for population to reach 1.6 billion; then it shot to 6.1 billion over just 100 years. The primary cause of population growth is an imbalance between births and deaths. The infant mortality rate has decreased globally, with 4.1 million infant deaths in 2017 compared to 8.8 million in 1990, according to the World Health Organization (WHO). POPULATION GROWTH AND SEA LEVEL RISE¡¦..RELATION More people means more demand for oil, gas, coal and other fuels mined or drilled from below the Earth¡¯s surface that, when burned, spew enough carbon dioxide (CO2) into the atmosphere to trap warm air inside like a greenhouse. Thus population growth tends to increase emissions of climate-changing greenhouse gases. As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea level. Scientists have measured the rate of sea-level rise at 0.13 inches (3.4 millimeters) per year. Thus it is clear that rapid population growth aids to the impacts of climate change by straining resources and exposing more people to climate-related risks—especially in low-resource regions.
