Où j'en suis dans mon devoir

J'ai déjà fais ça, si vous pouviez corriger, arrangez certaines choses et me dire ce qui ne va pas, cela m'arrangerais vraiment beaucoup.

"Agriculture has always been the largest user of water, demand from industry and cities, particularly in the South rising rapidly. The largest consumers are the countries where irrigated agriculture is important. For example, in the Imperial Valley there is the largest irrigated area in the US. 78% of Californian waters are being used by the agricultural sector. Moreover, since antiquity, men build hydraulic installations to use water like groundwater and rivers. Older dams have at least four thousand years. In central Arizona for example, there’s a project to build a giant aqueduct to supply the phoenix are with water. This project is one of the most expensive transfect systems in history ever. That projects dried up rivers and pollute the water. The grown surfaces decreases, there is less water so the crops are smaller. When there are less cultures, there are less food and insecurity’s food may happen."

merci d'avance.
