Слайд 2There are many environmental problems
Слайд 12Elephant is the largest terrestrial animal.
Traditionally, two species are
recognized,
the African elephant
and the Asian elephant.
Слайд 14 They are identified by their massive bodies and their
trunk, which is used to pick a variety of objects,
including food. Living members of the order Proboscides have a maximum height of nearly 4m and a weight of up to 7,500kg. The head is large in relation to the rest of the body, and African elephants are noted for their very large ears.
Слайд 15Both African elephants and Asian elephants need a lot of
food and freedom to survive. They wander in small to
large herds over sometimes incredibly large areas, while consuming up to several hundred kilograms of plant matter in a single day.
Слайд 16The two main historical factors behind the decline of African
elephants:
Demand for ivory
Changes in land-use
Слайд 18In the early 1970s, most of the ivory leaving Africa
was taken illegally and over 80%
of all the raw ivory
traded came from poached elephants
Слайд 19In the first decade of this century, there was killed
each year to 100 thousand elephants, and in 1980s years
in Kenya alone, poachers have destroyed about 20,000 of these animals every year.
