PROBLEMS
ARCTIC
The arctic is in the north and
south parts of the world. It is
in Alaska, Canada, Antarctica
and more places.
It has cold winters and cool
summers. Precipitation is low
and mostly comes in the form
of snow. The sun shines only
from March to September
There are now approximately 4
million people living
permanently in the Arctic .
The main indigenous group are
the inuits.
The Arctic is affected by
current global warming.
Arctic ice is getting thinner,
melting and rupturing, so the
ecosystem is changing and
some animals are dying.
natural resources were
exploited.
Most deserts lie along the
Tropic of Cancer and Tropic
of Capricorn.
They are characterized
by little vegetation and
rain. They are made up
of sand or rocks and
gravel.
There are oasis on the
deserts, which are
formed by a pool of
water, so it
allows people to settle
in the desert and even
grow crops.
The two major
classifications are hot
and cold.
The main form of precipitation
in a hot desert is rain. But
that's only ten inches or less
of rain per year.
The main form of precipitation
in a cold desert is snow or fog
The desert is the hottest
biome on earth. However, the
desert is also a land of
extremes. It can be over 100
degrees Fahrenheit during the
day but below 32 degrees at
night.
The arctic does not have
many plants. It has some
lichens, flowers, grass,
shrubs and moss.
Animals: gray wolves,
polar bears,puffins,
different kind of fish.
oil, minerals, and
diamonds in the North,
Plants called xerophytes
like cacti. Yucca plant, The
Indians use them to make
baskets.
Animals: Rattlesnakes,
Turkey Vulture , camels,
fox
DESERTS
The Bedouin : nomadic desert
life by breeding camels,
Arabian horses, and sheep;
grown date palms and other
crops, usually hiring others to
perform agricultural labour.
The Bushmen have lived in the
Kalahari for 20,000 years as
hunter-gatherers
The aboriginal people of the
desert in Australia fall into two
main groups: the Martu in the
west and the Pintupi in the
east.
The lack of water, so lack of
plants and different kind of
animals too.
TROPICAL RAIN FOREST
They are found in Africa,
Asia ,Australia, and Central
and South America. The
largest Rainforest in the world
is the Amazon Rainforest.
Rainforests are also found in
the tropics between the
Tropic of Capricorn and
Tropic of Cancer.
contain a lot of trees.
It always has a warm climate
so it is not so cold. It rains
very much.
the sun is very strong and
shines making the climate
warm and stable.
The rainforest climate is very
hot and humid
3 groups:
-People living as nomadic
hunters and gatherers
-native peasants with a long
tradition of crop rotation.
- settlers: landless farmers, big
landowners and timber and
construction workers
OCEANS
Atlantic, Pacific , Indian, arctic
and Antarctic.
70% of the planet’s
surface is covered by
water
Average depth of the
ocean: 3000 meters
Life in the oceans is
distributed over 3
dimensions
There is a very high
diversity of marine
environments
The average temperature of
all oceans is about 39
degrees F (3.8 degrees C).
But the oceans in different
parts of the world have very
different climates!Tropical
oceans, which are near the
equator, are warm and clear
on the surface. But in the cold
polar regions of the far north
and far south, the ocean is so
cold that its' surface is frozen.
Animals as Mammals
Birds, Reptiles
Amphibians
Insects
Around two-thirds of the
world’s plants are found in
the Tropical Rainforests
used for medicines, food
and specially to get the
oxygen needed in the
world.
Plankton
Phytoplancton
Zooplankton
Neckton
Crustaceans
molluscs

Fish
Marine mammals
The effects on the tropical
rainforest because of human
activities are: They chopped
down the trees that block the
sunlight. Therefore
increasing temperature.
They take minerals, flowers,
and other things. To make
beverages and medicine.
They kill animals in order to
get food.
Over fishing

Oil spills
Noise pollution
