High School Earth Science: Ecosystems and Human Populations - Human Populations — Flashcards

The current world population is 8,064,361,298 as of Wednesday, October 4, 2023, according to the most recent United Nations estimates.

A topic generating a great deal of discussion these days is sustainable development. Sustainable development is any economic development that allows people to escape a life of poverty while conserving resources and protecting the environment. Many different approaches must be adopted to achieve these goals.    
One of the most important steps to achieving sustainable development is reducing the rate of human population growth. If there were a smaller number of people, fewer resources would be needed and smaller amounts of pollution and greenhouse gases would be released. One way to slow human population growth is to provide education for girls and women in countries where they typically go without education. Studies have shown that as women become educated, they tend to have fewer children.    
Advances in science and technology are likely to be an important part of sustainable development. If scientists had a better understanding of how Earth’s natural systems work, they would also have a better understanding of how people are affecting them. Technologies could also be developed to help solve problems created by overpopulation and overuse of resources. An example of a technology that could aid sustainable development is fish farming, as long as it is done in environmentally sound ways. Raising fish on farms rather than relying solely on wild fish could reduce the risk of overharvesting wild fish populations. Another example is the development of cleaner energy sources that would reduce pollution and greenhouse gas emissions.    
Individuals can also play a role in achieving sustainable development. This applies primarily to people in the developed nations. They could change their behavior to reduce the impact they have on the planet. They could consume only what they need and avoid wasting resources. They could also try to limit their purchases to products that are produced sustainably. For example, they could choose to purchase wood products only from companies that plant new trees to replace those that are cut down.
