The Yangtze River

Construction

The construction of the Three Gorges Dam on the Yangtze River was a monumental undertaking that spanned nearly two decades. Initially proposed by Dr. Sun Yat-sen, the dam aimed to control flooding and generate electricity, but faced numerous delays due to political upheavals and environmental concerns. Despite these challenges, construction began in 1994 and was completed in 2012, making it the largest dam in the world at 2.3 kilometers long 1.

The dam used 27.2 million cement and enough steel to build the Eiffel Tower.

Its completion significantly increased the river's freight capacity and reduced transportation costs, highlighting its economic impact on China 1.

   

Environmental Impact

The construction of the Three Gorges Dam was not without controversy, particularly regarding its environmental and cultural impact. The dam's reservoir submerged numerous communities and cultural sites, raising significant concerns about the loss of biodiversity and heritage. Despite these issues, the Chinese government proceeded with the project, which was approved with only 67% support in the National People's Congress, a notably low percentage for such decisions 1.

The lake created by such a dam would destroy many communities along the river, cultural sites, as well as plant and animal species.

Efforts are now being made to address the environmental challenges, particularly the river's plastic pollution, which is a major contributor to oceanic waste 1.
