Write a 200-300 word response addressing the following points: What is the current estimate of the worldwide human population at this moment? Describe how this number is changing moment-to-moment, day-to-day, and from one year to the next. Describe how the human population growth issue has and will affect the ecosystem.
I am having problems find the answers to the second part of the question where it says to Describe how this number is changing moment to moment, day to day, and from one year to the next and Describe how the human population growth issue has and will affect the ecosystem. Please help me on this.
World population is curren;y increasing at a rate of 77 million people, or 1.2%, per year. Divide that by 365 to get the rate per day, which is 210,000. Divide that by 1440 minutes/day for the number of people per minute.
The average energy consumption per person has been growing along with the population. There is already not enough fresh water to support much of the world's population.
I recommend that you do your own research on the effects of future shortage of water, energy, and arable land that will result, as well as the loss of habitat for endangered animals. Increasing population will increase in "greenhouse" gases (mainly CO2) in the atmosphere and lead to global warming and rising sea level.
To find information on the current estimate of the worldwide human population and how it is changing, there are several reliable sources you can consult. One of the most reputable sources is the United Nations (UN), which compiles data on population growth and provides forecasts. The UN's Department of Economic and Social Affairs (DESA) regularly updates their estimates and projections on world population. Their website or official reports would be a good place to start your search.
Additionally, the World Bank, the US Census Bureau, and other reputable organizations also provide data on population growth and estimates. Their websites or reports would be helpful in providing the most up-to-date information.
In terms of how the human population is changing moment-to-moment, day-to-day, and from one year to the next, this requires analyzing birth rates, death rates, migration patterns, and other demographic factors. The growth rate of the human population is affected by factors such as fertility, mortality, and international migration. By studying these factors, demographers can estimate population changes over specific timeframes.
Regarding the impact of population growth on the ecosystem, there are numerous ways in which it can affect the environment. Increases in human population lead to higher demands for natural resources such as land, water, and energy. This can result in deforestation, habitat loss, pollution, and the depletion of natural resources. Moreover, the growing human population puts pressure on ecosystems, impacting biodiversity and leading to the extinction of species.
Additionally, population growth also leads to increased consumption and waste generation, contributing to climate change and other environmental issues. It is important to address population growth in sustainable development plans to mitigate its impact on the ecosystem. Policies aimed at promoting family planning, education, and sustainable resource management are often considered effective in managing the effects of population growth on the environment.
