habitat - (1) the
natural home of an
animal or plant; (2) the
sum of the environmental
conditions that
determine the existence
of a community in a
specific place.
harpooning - a
surface method of
fishing that requires
considerable effort in
locating and chasing
individual fish.
Harpoons are hand-held
or fired from a harpoon
gun and aimed at
high-value fish, such as
giant tuna and
swordfish.
haze - an
atmospheric condition
marked by a slight
reduction in atmospheric
visibility, resulting
from the formation of
photochemical
smog, radiation of
heat from the ground
surface on hot days, or
the development of a
thin mist.
high seas -
international ocean
water under no single
country's legal
jurisdiction.
highly migratory
fish - fish that
travel over great areas.
household hazards
- dangerous substances
or conditions in human
dwellings.
hydroelectric
- relating to electric
energy produced by
moving water.
hydrofluorocarbons
- used as solvents and
cleaners in the
semiconductor industry,
among others; experts
say that they possess
global warming
potentials that are
thousands of times
greater than CO2.
hydropower -
energy or power produced
by moving water.
hypoxia - the
depletion of dissolved
oxygen in water, a
condition resulting from
an overabundance of
nutrients of human or
natural origin that
stimulates the growth of
algae, which in turn die
and require large
amounts of oxygen as the
algae decompose. It was
the most frequently
cited direct cause of
fishkills in the U.S.
from 1980 to 1989.
