    There are many different kinds of misconceptions related to understanding human population issues, some of
    which result from lack of clarity about terms. Whenever the term “human population growth” is used,
    misunderstandings arise. Population growth is defined as the limiting of population increase to the number of live
    births needed to replace the existing population. However, focus on “population growth” can be perceived to be
    a need to control human reproduction rights and use of the word “control” sets off a red flag, especially for
    countries based on democratic principles.
    There can also be a lack of clarity when people use the term rate of population growth or decline. People need to
    be aware that the rate of human population growth can decline, while the absolute number of people on Earth
    can continue to increase. Also important to recognize is that areas experiencing rapid population growth are also
    often areas where the majority of Earth’s remaining biodiversity can be found.
    Another misconception about population growth occurs when people assume that developing countries must go
    through the same processes, steps, or trends that developed countries have gone through. “Leapfrogging,” a
    concept that developing countries can adopt modern systems without going through all the intermediary steps,
    is an important process when thinking about global development and population issues.
    The idea that population problems of developing countries are not a problem for the United States is a
    misconception. The scale of human activities is now so large that humans are appreciably affecting the climate
    and ecosystems in the U.S. and the world. The total impact of people on the environment is proportional to the
    number of people and the average impact of each person. If we are to reduce the total impact of people on the
    global environment, we must address both factors.
    Another popular misconception is that the world’s worst population problem is found in developing countries.
    The United States has a high per capita resource consumption. Some estimates say a person in the United States
    has 30 times or more impact on world resources than does a person in an underdeveloped nation.
    The notion that all growth is good is a misconception. Steady growth of towns and cities has often been the goal
    to which communities aspire. If a town’s population is growing, the town is said to be “healthy” or “vibrant,” and if
    the population is not growing the town is said to be “stagnant.” However, something that is not growing could
    alternately be viewed as “stable” and good.
