Saving Cambodia's dolphins

The video discusses the critical situation of the Mekong freshwater dolphin, also known as the Irrawaddy dolphin, which is critically endangered with fewer than 80 individuals left. River guards are working to protect these dolphins from threats like fishing techniques and habitat destruction. Despite these efforts, the dolphin population remains at risk due to massive development projects, particularly dam construction, which disrupts the ecosystem. The video highlights the need for international cooperation and new conservation strategies to prevent the extinction of this species.

What is one of the main tasks of the river guards in protecting the Mekong dolphins?

• Building dams to control water flow

• Organizing dolphin-watching tours

• Preventing the use of harmful fishing methods

• Introducing new fish species to the river

Why is the Mekong River dolphin considered critically endangered?

• Owing to the introduction of invasive species

• As a result of pollution from nearby factories

• Because of the imbalance between births and deaths

• Due to overfishing by international companies

How do dams affect the Mekong River's ecosystem?

• They increase the river's water temperature

• They block fish migration and breeding

• They reduce the river's water level

• They enhance the river's biodiversity

Which country has not joined the Mekong River Commission's harm reduction strategy?

• Laos

• China

• Thailand

• Vietnam

What is Cambodia's proposed solution to help the dolphin population?

• Building more dams

• Creating a breeding program away from the river
