Transcript of Overpopulation Eco15
by Veronika Solonynko
With intensifying population growth, pressure is exerted on the carrying capacity of Earth and its limited resources. The population increases exponentially, which means pollution, resource use, and environmental damages are also increasing at exponential rates. This pushes us past the point of sustainability.
The onset of the
agricultural and industrial revolutions
, as well as
advancements in modern medicine
encouraged the growth of the world population in an
fashion. Developing countries contribute greatly to the total world population due to high birth rates and low life expectancies.
How Overpopulation Came To Be
Carrying capacity is the number of organisms the Earth can support over a long period of time, which is an estimated 500,000-1,000 billion--a figure we have well exceeded.
It is determined by resource availability and the environment's ability to safely absorb and detoxify wastes.
It fluctuates depending on factors such as climate.
Only humans can expand the carrying capacity, usually at the expense of other species.
Allow people full reproductive rights, such as easy access to contraception and other family-planning methods (Thailand)
Spread awareness of the causes and effects of overpopulation
Educate people, particularly in developing countries, about overpopulation and provide them with the necessary tools to make the decisions they want
Use renewable resources and solar energy instead of depleting fossil fuels to lessen the effects of overpopulation, such as pollution
Stricter government regulation
Hans Rosling's suggestion: "continue to improve child survival to 90 percent"
Overpopulation is a condition defined by an enlarged population density that is a result of an increase in births, a decline in mortality rates, an increase in immigration. Overpopulation provokes environmental deterioration and a decline in the quality of life.
Habitat destruction and increased habitat loss, species extinction, resource depletion, loss of fresh water resources, war, crime, unemployment, traffic, pollution, inner city syndrome (crowding in urban centers causing social, mental, and physical implications), homelessness, hunger, increase of new epidemics and pandemics, less freedom and more restrictions, unsanitary living conditions, increased global warming and climate change...
