Some species of Antarctic animals have been taken to the verge of extinction for economic
benefit. Others have been killed incidentally or disturbed, soils have been contaminated, untreated
sewage has been discharged into the sea and rubbish that will not decompose or break down for
hundreds of years has been left behind in even the remotest parts.
~Fishing is one problem :( ~Pollution
~Exploitation and exploration
~Tourism is another problem
~Mining and oil that's another problem
~And human impacts...
Thank You for watching!!!!!!!!!!!!!!!!!!!!!!!!!
There is a little number of flora, but the most numerous plants are species of algae, moss, lichen and
mushroom. They grow horizontally.
Polar bears are affected by decreasing sea ice
The global population of polar bears is predicted to decrease by 30% in
the next 45 years.
Arctic and surrounding seas produce more than 10% of global marine
fisheries catches by weight
The Arctic and surrounding seas also account for 5.3% of the world's
crustean catch by weight.
What is a Chaparral?
A Chaparral is a shrubby coastal area that has hot dry
summers and mild, cool, rainy winters. Chaparrals consist of
regions of tall, dense shrubs with leathery leaves or needles.
Where are Chaparrals located?
Chaparrals are located in bands between 30 and 40 degrees N and 30 and 40 degrees S of the equator.
These coastal regions have cold ocean currents offshore; they are coasts that face west.
They occur in the southern coast of California (USA), the coastal areas of the Mediterranean Sea, the
coast of Chile (South America), the Cape region of South Africa, and coastal Australia.
Most are animals and desert grassland types that can adapt to the hot and dry
Birds make their nests in the ground to protect themselves from the heat and
Furry animals have short fur that can change the length to suit the season or in
accordance with their environment.
Reptiles hunt at night to avoid the heat.
Plants must adapt to heat, little moisture, and poor soil. Plants have small, hard
leaves which hold moisture. Because brush fires are frequent, many plants are
small. Examples of plants: oak, scattered scrub, large shrubs, cacti.
Prairies are located in the interior of North America.
A prairie is a temperate grassland, plains of grass that get hot in the summer and
cold in the winter. ( 0 ° degrees to 40º degrees) .
Many types of animals live in the Prairies but
here are the most important. We have put them
here because they rather affect the food chain
and some of them are beautiful.
FLOR The grass is the dominant plant but also
there are other plants.
BIG BLUESTEM GRASS
Indian tribes lived in the prairies which were
thrown to other places, and the first ranchers
were installed who took care of their lands to

The savanna is a hot, seasonally dry grassland with scattered trees. This
environment is intermediate between a grassland and a forest. Savannas have an
extended dry season and a rainy season.
There are located in Africa, Madagascar, Australia, South America, India, and the
Myanmar-Thailand region of Southeast Asia.
In the taiga, grow mainly conifers, moss and lichens.
There are many types of trees, but most of them are pines.
IT IS ENDANGERED?
There are some endangered animals
and plants, this are some examples:
Animals: Siberian tiger, Peregrine
falcon, Snow leopard…
Plants: Labrador tea, Long leaf pine,
The taiga is characterized by a cold, harsh climate, a low rate of precipitation
(snow and rain), and short growing season.Taigas are relatively low in animal
diversity because of the harsh winters.
PEOPLE WHO LIVE THERE
There are a few large cities in the southern parts of the taiga, such as Moscow
and Toronto, but most of it is relatively unpopulated. There are also a few native
communities of people who still live indigenously in the taiga.
Temperate forests are famous because of their leaves
in Autumn, their colors vary between red, orange,
yellow and brown.It usually rains a lot, and the soil is
very rich in nutrients because lots of little animals and
leaves fall on the floor and decompose
Description of Tundra
● The tundra is a cold, treeless area; it is the coldest biome. The
tundra is characterized by very low temperatures, very little
precipitation (rain or snow), a short growing season, few nutrients,
and low biological diversity.
● The tundra is located near the North Pole, in the top of
the world. This enormous biome covers a fifth of the
● The snowy owl (Nyctea
scandiaca) is a bird that
lives in the tundra of North
● The Arctic fox (Alopex
lagopus) is a furry mammal
that lives in the far north, in
● Arctic Tundra: Because the
climate in the Tundra Biome is
particularly inhospitable settings,
the flowers found within the
biome are very few.
● Alpine Tundra: The plants that
grow within this Tundra Biome
are called Alpine Plants. The
most abundant plant is the
Problems that affect the Tundra
● Lichens are a dominant life form on the tundra, and they are particularly
vulnerable to air pollution. Because of this, lichens have historically been
used as air pollution indicators. Air pollution has also led to a persistent 'arctic
haze' that contributes to acid rain and settles on the ground, hastening
Problems that affect the Tundra (II)
● In addition to global concerns, ecosystem imbalances can have
profound regional impacts. For example, the snow geese nesting
on Canadian tundra have increased by 5 to 7 percent annually
People who live in the Tundra
● Inuit: They live along the coast
and hunt caribou, seal, whales
and fish. They speak Inuktitut
which includes seven different
● Yakut:They live in Siberia
tundras. They hunt to get
animals furs. They change
locations twice a year.
