University students are wearing green ribbons around their wrists throughout November as part of a campaign to raise awareness of anti-littering.
The students' efforts are the result of an initiative by RMIT Vietnam's Green Ribbon organisation, also known as Ruy Băng Xanh or RBX in Vietnamese.
The organisation has recently launched the RBX month, an annual event which aims to raise awareness of littering among students and young people across Vietnam through the simple action of tying green ribbons on wrists.
This year, the month also features an activity called the Green Lesson.
Practices for a clean and green environment will be shared with young people at workshops across Ho Chi Minh City, Hanoi, Can Tho and the Central Highlands.
RMIT Vietnam Senior Lecturer and RBX founder Mr Nguyen Huu Nhan has always been concerned about littering in Vietnam and focused on how to raise awareness about the topic.
"Littering is the environmental issue I worry about the most," Mr Nhan said.
"We often focus on significant environmental issues such as global warming, sustainability, and climate change but we also need to consider simple but effective actions for the environment such as stopping littering."
RMIT Vietnam student Nguyen Tran Khanh Chi, Project Leader of the Green Lesson, said it's important for the future generation to understand environmental issues.
"We're really inspired to drive action within our generation towards protecting the environment," Chi said.
"We can do this through activities such as the Green Lesson."
"Through this simple but engaging approach, we believe attendees will remember the message we want to convey."
Participation in this year's RBX month has expanded to 15 universities from nine in 2013.
