By Raquel Robledo & Sara Nogales In most of the rich countries,like Europe in general and America, they had pure water in they own homes. But in Africa the water has a lot of impurities like in the photo and its very difficult to find water.They had to collect water from the puddles or they had to make potholes in the ground. In the same parts, in europe and america ,they can have a bath in they own homes. But instead of this ,in africa they dont have baths or they was themselves in a balde. Also some aquatic animals and plants need water to survive and breathe. If these animals don't have water they could die. A terrible accident was when the Prestige sank in 2002. The petroleum pollute the coasts of the North of Portugal,the Landas in France and Spain. Also some acids makes the water acidic. The acidic water is bad for us and helps to the erosion on rocks. With this water the trees are kill. A ship sank near a beach, but the ship only pollute one or two km with his own fuel. The ship was called Sierra Nava in 02/02/07. In Zumaia (Guipúzcoa) was also affected by the petroleum, like you can see in the photo. We can solve all these problems using less water in our life. For pollute less the air; this contribute to the health of the water. Having more sources for when a ship like the Prestige sanks.
