Intro :

Hello, I will present you the notion of spaces and exchanges. This notion deals with the geographical and symbolic areas that all societies occupy and the interactions between men and different societies. Our world built on the exploration and conquest of new spaces. The different cultural, economic, sociological and language interactions have shaped and characterised our modern day world. It will be interesting to answer the next question : How have the conquest of man involved since the 1870 ?
In the first time we will see the conquest of the west and in second time the conquest of the space.

Développement :

Firstly, the first document entitled “broken dreams”presents the conquest of the west. The pionners hope to have a large and productive farmIn effect and a state with innumerable lakes,luxuriant forests and the healthiest climate in the world. In reality, the climate is harsh in the great plains (tornado, hail storms, prairie fires...) In effects when the first English settlers reached the New World, over 40 million people have migrated to the United States. All Americans are immigrants or children of immigrants. The second document

Secondly, the last document is a texts by kennedy on the new frontier which represent the conquest of the space. He's talk about the earth space's frontier. The space have many freeways and give us lot of challenge and security. The space give infinity space to be exploited because the earth have a limited space and limited ressources. The conquest of the space is market on july 20,1969, when Neil Armstrong was the first man to walk on the Moon, mission « Apollo II ». This great achievement catapulted America's reputation in the space race. This was allowed thanks to the development of new technologies

Conclusion :

Since 1870 the conquests of man have improved significantly. First of all, with the conquest of the west with the immigration of the English, then afterwards, which was a major event for the world, it is the conquest of space. The United States affirmed their space power in 1969 being the first country to send a man to the moon.
How today, the United States can meet the challenge of making Mars habitable?
