Indoor air pollution is a significant source of human death and
diseasemortality and
_________________through indoor burning of wood and charcoal
(especially in developing
countries), tobacco smoking, radon trapping and a host of
chemical substances found in paints,
printing supplies and cleaning products.
Thermal pollution is the act of altering the _________________
of a natural water body, which may be
a river, lake or ocean environment.
The concept is most frequently discussed in the context of
elevating natural water temperature, butmay also be caused by the
release of cooler water from the base of _________________ into
warmer
rivers.
Elevated river temperatures can also arise from
_________________ or urbanization that can
reduce _________________.
There can be significant environmental consequences of thermal
pollution with respect to surface
receiving waters such as rivers and lakes; in particular,
decrease in _________________ and creation of
an environment hospitable to alien aquatic species may
occur.
An alien species is an organism that finds itself in a new
geographic location or _________________.
Many of these species arrive in the new location due to
inadvertent human activities such as shippingor agriculture,
although many are purposefully introduced for food cultivation or
for attempts (usually
misguided) at ecological intervention.
Water pollution is the _________________ of natural water bodies
by chemical, physical, radioactive
or pathogenic microbial substances.
Widespread consequences of water pollution upon ecosystems
include _________________
mortality, biodiversity reduction and loss of ecosystem
services.
Some water pollution may occur from natural causes such as
_________________ from severe rainfall
events; however, natural causes, including volcanic eruptions
and algae blooms from natural causes
constitute a minute amount of the instances of worldwide water
pollution.
The most problematic of water pollutants are microbes that
induce disease, since their sources may
be construed as natural, but a preponderance of these instances
result from human intervention in
the environment (such as discharge of raw _________________) or
human overpopulation
phenomena.
One of the chief causes of water pollution is agricultural
activity where _________________ practices,
fertilizer, pesticide and herbicide use create massive amounts
of sedimentation and chemical
discharge to natural waters.
