Discuss if the following technologies mentioned in the Listening can be used in Viet Nam

Turning methane emissions from cows into energy: This technology can definitely be used in Vietnam as the country has a large population of cows, which results in the emission of a significant amount of methane. With this technology, the methane gas can be captured and converted into biogas or electricity, which can be used to power households and industries. By using this technology, we can reduce the release of methane into the atmosphere, which is a potent greenhouse gas, and help slow down global warming.

Growing plants in the ocean: Growing plants in the ocean, also known as ocean farming, can be a feasible technology for Vietnam, given its long coastline. This method involves growing various types of seaweed and other marine plants to help absorb carbon dioxide from the atmosphere. Additionally, these plants can be used as a source of food, biofuel, and other products. By growing these plants, we can reduce the amount of carbon dioxide in the atmosphere and help mitigate climate change.

Keeping CO2 in storage sites: Carbon capture and storage (CCS) technology can be a useful method to reduce carbon dioxide emissions in Vietnam, particularly in the industrial sector. However, there are some challenges with the implementation of CCS technology, such as the lack of suitable storage sites and the high cost of capturing and storing CO2. Nevertheless, if properly implemented, this technology can help reduce CO2 emissions, thereby mitigating climate change.
