Trouble on the Mekong: Negative Effect of Dams on the Mekong River

The video discusses the rising energy demand in Asia, with a focus on the Mekong region's shift from fossil fuels to hydropower as a cleaner alternative. It highlights the environmental impacts of hydropower dams, such as altering river systems and affecting delta communities. The video also addresses the threats to mangrove ecosystems due to reduced water supply and increased salinity, emphasizing their importance for carbon storage and biodiversity.

What is the expected rise in Asia's energy consumption over the next 20 years?

• 65%

• 75%

• 55%

• 45%

Why are hydropower dams considered a cleaner energy source?

• They are cheaper to build.

• They require less maintenance.

• They use fossil fuels efficiently.

• They do not emit greenhouse gases.

What is one major drawback of hydropower plants on river systems?

• They reduce sediment in the ocean.

• They block and divert natural river courses.

• They enhance fish biodiversity.

• They increase water flow.

How does the reduction in water supply affect the Mekong Delta?

• It increases fish population.

• It reduces saline levels.

• It enhances mangrove growth.

• It causes the delta to sink.

Why are mangrove forests important for the environment?

• They increase global temperatures.

• They are carbon-rich and support biodiversity.

• They are a source of fossil fuels.

• They are used for building materials.
