As it can be understood from the passage, while some measures are taken to protect species’ habitats, ----.
Conservation biologists are applying their
understanding of population, community, ecosystem,
and landscape dynamics in establishing parks,
wilderness areas, and other legally protected nature
reserves. Choosing locations for protection often
focuses on biodiversity hot spots. These relatively small
areas have a large number of endangered and
threatened species and an exceptional concentration of
endemic species, those that are found nowhere else.
Together, the “hottest” of Earth’s biodiversity hot spots
total less than 1.5% of Earth’s land but are home to a
third of all species of plants and vertebrates. There are
also hot spots in aquatic ecosystems, such as certain
river systems and coral reefs. Because endemic
species are limited to specific areas, they are highly
sensitive to deprivation of their natural environment. At
the current rate of human development, some biologists
estimate that loss of habitat will cause the extinction of
about half of the species in terrestrial biodiversity hot
spots in the next 10 to 15 years. Thus, biodiversity hot
spots can also be hot spots of extinction. They rank
high on the list of areas demanding strong global
conservation efforts. Concentrations of species provide
an opportunity to protect many species in very limited
areas. However, species endangerment is truly a global
problem, and focusing on hot spots should not detract
from efforts to conserve habitats and species diversity
in other areas.
