Environmental Science: Population Density in the Philippines

Study Notes

In Metro Manila, the population density is 21,765 persons per square kilometer, 60 times the national average.
The City of Manila has the highest density at over 73,920 people per square kilometer.
The most densely populated provinces are Cavite, Rizal, Laguna, Bulacan, and Pampanga.
The global human population has reached over 6.7 billion, driven by factors such as the agricultural revolution, industrial revolution, sanitation, and medicine.

Thomas Malthus published "An Essay on the Principle of Population" in 1798, warning about the disparity between population growth and food supply.
Malthus argued that population growth must be restricted, or it will lead to starvation, war, and disease.

The 1968 book "The Population Bomb" by Paul and Anne Ehrlich predicted worldwide famine and societal disruption due to overpopulation.
The book advocated for immediate action to limit population growth.

The Tragedy of the Commons, described by Garrett Hardin in 1968, occurs when shared environmental resources are overused and depleted.
The tragedy arises because individuals neglect the negative externality of their actions on the shared resource.

Environmental science is an interdisciplinary field that studies the natural world and develops solutions to environmental problems.
The ecological footprint measures human demand on natural capital, including the biologically productive land and sea area needed to provide resources and absorb waste.
The ecological footprint of developed countries is significantly larger than that of developing countries.
Humans are using 30% more of the planet's resources than are available on a sustainable basis.

Environmental problems vary in perception between individuals and societies.
The pursuit of knowledge about the natural world is distinct from environmentalism, a social movement dedicated to protecting the environment.
Human population growth and consumption aggravate environmental problems, and reducing consumption is essential to mitigating these issues.
Solutions to environmental problems include private ownership, voluntary organization, and governmental regulations to enforce responsible resource use.
