are not native are termed as exotics.
v They can
be thought of as Biological Pollutants and are considered to be among the most
damaging agents of habitat alteration and degradation the world.
2 Climate change

change may simply shift these distributions but, for a number of reasons,
plants and animals may not be able to adjust.
ENDANGERED SPECIES
v According
to The International Union of Conservation of Nature and Natural Resources
(IUCN), the species that considered in imminent danger of extinction and whose
survival is unlikely, if factors causing their decline continue to operate.
v Out of
about 47,000 species of plants in our country, 7000 are endemic
v India
