iChange Plastics, a pro-environment campaign in Vietnam, is encouraging local youth to take up the “3210 Challenge” to reduce plastic waste in their daily life and win great rewards.

The program is translated as “3 weeks, 21 challenges, and 0 plastic waste.”

The initiative includes a set of challenges designed to change the habit of plastic consumption and limit the use of plastic products.

The program hopes to see participants gradually cut out their use of disposable plastic products such as plastic bag, straw, or bottled water.

The challenge is being held on Facebook by the Center for Action and Alliance for Environment and Development (CHANGE) from June 25 to July 16, 2018.

To participate in "3210 Challenge", any individual with a Facebook account can visit the CHANGE’s Facebook page from the beginning of every day to receive the challenge of that day.

Participants are not allowed to use plastic in 21 days and have 24 hours to complete each challenge.

The initiative encourages people to avoid using disposable plastic products.

After finish the challenge of the day, participants have to write a story about how they did it, plus a photo proof of their act and share them on Facebook with the hashtags #3210 #iCHANGEPlastics #PJsCoffeeVietnam.

Winners can receive environmentally-friendly gifts including bicycles, electronic readers and air purifiers. The biggest prize is a VND10 million (US$440) trip to Singapore.

Vietnam is one of the five nations with the biggest volume of plastic trash in the world. The country dumps some 1.8 million metric tons of plastic waste into the oceans on an annual basis.

Plastic waste not only seriously affects marine creatures but also human health.
