emigrations).
HUMAN POPULATION

8.2 billion
It is expected to expand and peak at approximately
________ around the mid-2080s. Population levels are then
anticipated to experience a slight decline, settling at around
_________.

_______ and ______ remain the two most populous
countries of the world, both with more than 1 billion people,

population, respectively.
India, China
The issue of
overpopulation is most
pronounced in areas
like _________. (In the Philippines)

116 138 484
___________ is the increase in the

Human population growth
_________ is the term used to describe the

Population explosion
The impact of human population growth on the
environment takes two major forms:
- CONSUMPTION OF RESOURCES
- PRODUCTION OF WASTES
The __________
from the environment often
releases pollutants and
waste that reduce air and
water quality, and harm the
health of humans and other

extraction of resources
_________- are burned for
energy to generate

gases.
_________ is extracted
from lakes, rivers, the
ground, and man-made
reservoirs for drinking,
agriculture, recreation, and
industrial processes.
Freshwater
______ leads to
land use changes due to
the increased demand for

agriculture, resulting in
deforestation and
biodiversity loss.
__________
reduce the population of
the exploited species.
Consequently, species can
be prone to become
endangered or extinct.
Overfishing and hunting
As people travel, import, and export
supplies, urbanization creates
disturbed environments where
invasive species often thrive and
outcompete native species.
Mahogany trees in the
Philippines native tree species
INCREASE IN THE TRANSPORT
OF INVASIVE SPECIES
___________ areas can rapidly
spread diseases within and among

__________, in which a disease
transmits from humans to animals,
