What are the environmental effects of water conservancy projects?水利工程对环境有什么影响?请用英语回答.
Well,I think there are both positive and negative effects of building water conservancy projects.
As we all know,building hydro projects such as a dam will help protecting city from being attacted by floods and it can be useful in the regulation and distribution of water so that we can guarantee people's need for water in daily life and production.In this sense,hydraulic engineering has beneficially environmental effects for human being.
However,at the same time,we should not ignore the adverse effects of hydro projects.Firstly,building water conservancy projects will cost a lot,it needs enough funds,advanced expertise and long time limits for projects.In other words,it will not only harass the people but also waste money.Secondly,the project may turn to disturb the balance of environment and ecosystem.For example,the Three Gorges Hydropower Station has proved to have effects on the climate of Province Sichuan and induces the serious earthquake in Wenchuan in 2008.
So I think we really need to be so cautious to building water conservancy projects considering of its two sides of environmental effects that we won't do the well-meaning but be misguided at last.
