All these wastewaters have

of the systems which can lead to waste disposal issues. Re-circulating aquaculture needs to have excess nutrients removed from the system, normally this means that a percentage of the water is removed, generally on a daily basis. This nutrient rich water then needs to be disposed of and replaced with clean fresh water. While re-circulating aquaculture and hydroponics are both very efficient methods of producing fish and vegetables, when we look at combining the two, these negative aspects are turned

begin to use renewable energies, if the consummation of CO2 and the consummation of water slow down in these countries and to finish we will speak about the money which is dedicate at the environment by these European countries. These datum are analysed from 1998 to 2007. I think that with these four type of data, we have a range of all the matters which are concerned by the environment: we speak about the water, the atmosphere, the energy and the investment for protecting the environment. 1/

the demand, on a very large point of view, is growing and specifically the one for water, either for drinking or not-for-drinking consumption. Actually it is a well known fact that access to water is going to be one of the most important issues of our time, with a forecasted worldwide population of over 9 billion people by 2025. Talking about figures and so as to illustrate the purpose above, the total US water industry on its own represents a market of over $106 billion. To succeed in this era

the resources it owns, and in particular the water it owns. The lack of water will be in a very close future the first war cause, the ownership of water in our actual society will be soon an inestimable trophy. The interstate relations are nowadays articulated around the ownership of some resources considered like vital (water...) This is what constitutes the relative power, independence or the simple existence of country, the one which control water can easily control the international economy

solar tube collector in particular, would function in Finland, a country with a very harsh climate.The solar collector was assembled according to the manual provided by the manufacturer. The original plan was to connect the solar collector to the water (heat) network of the Eco- House located at Metropolia University of Applied sciences in Vantaa. Measurements were meant to be taken during the coldest months of winter, when the solar irradiation is at its minimum.During the assembling of the collector

four main types of pollution : - Air pollution. - Pollution from sewage. - Oil pollution. - Drainage into rivers and oceans. 2. How does pollution affect rivers, oceans, and our ecosystem? The water can be polluted by chemical and product leaks , which may cause the animals who live in the water to get sick . Air pollution also has very negative effects on our atmosphere. There is a hole in our ozone due to pollution in the air. If this hole gets bigger we won’t be protected from the sunlight
