Going green. A plastic bag ban went into effect this month in Morocco. Green campaigners say that the country's consumers may need years to fully comply with the new law.

The bill, which became law on July 1, is part of a larger environmentally conscious effort across the North African country to go green. Morocco uses about 3 billion plastic bags a year, according to the Moroccan Industry Ministry. The U.S. uses about 100 billion a year, according to the Earth Policy Institute, and 1 trillion are used globally per year.

According to EcoWatch, Yassine Zegzouti, president of Mawarid, said changing consumer habits will be the toughest part. "The formal sector will need four to five years to comply with the new law," Zegzouti said. "But the use of plastic bags is anchored in [consumer] habit. All actors need to change these habits to not have any damage in the future."
