Extreme enviroments. In this presentation I’m going to talk about three extreme environments that are completely different. These environments are extreme, and we are not very adapted to that environments The North Pole The amazon (rainforest) The S ahelian Acacia savanna. The north pole.

People live in the amazon rainforest, lots of tribes and lots of different ethnic groups.
These people are adapted to that climate because they have been living there for such a long time that now they have adapted. They are adapted to eating tropical food, living in a tropical climate, building their own houses …
The SahelianAcacia savanna, it’s found in the northern hemisphere, in the continent of Africa and it passes through lots of countries from Africa in the north.
The Sahelian climate is a tropical semi-arid climate with the dry season mainly (but not exclusively) during the "cold" season (the coldest six months of the year):
It is tropical because the mean monthly temperature of the "coldest" month is equal to or greater than 18°C.
It is semi-arid because of low annual precipitation, below about 600 mm in a tropical climate (and above about 100–150 mm), characterized by irregular and unpredictable short rainy seasons through the years. The dry season generally lasts from about 8 to 11 months a year.
Though erratic, the rainy season in a Sahelian climate zone usually occurs during the warm season but not during the very hottest months.
The savanna is mostly covered by grass and bushes. But you can also find trees like the baobab, the acacia tree, The Candelabra Tree.
Yes people do live in theSahelian Acacia savanna. Theylivetherebecause Africa is growing, and theyhave to findsomewhere to live, obviouslymost of them are poor, becausetheycan’tpayfor a house.
Thesepoorpeoplehaveto walklots of kilometers to findsomefood and somewater to survive, and yettheylook as thoughtheywereliving in the U.S.A.
In conclusion I think that these three extreme environments are called like that because they are difficult for someone to adapt to.
I think that the most extreme ones are the ShahelianAcacia savanna and the North pole. I think this because they have very extreme temperatures; therefore, it is very difficult to survive. Also in the case of those environments is very difficult to be able to find water and food... But in the rainforest, you have the perfect temperature for a human to survive. The bad thing is that it is called extreme because of the animals that live there, they are very dangerous, and some of them very poisonous.
