Travelers are warned: don’t bring or carry plastic bags in Kenya. The production, selling or even use of plastic bags is prohibited in the East African country. Violators will risk imprisonment of up to four years or fines of $40,000 (or €33,000), as the world’s toughest law to reduce plastic pollution went into effect on 28th of August.Plastic bags cause many environmental problemsPlastic bags are a cause of many environmental concerns. Many bags drift into the ocean, where they suffocate seabirds, strangle turtles and fill the stomachs of dolphins and whales with waste until they die of starvation. “If we continue like this, by 2050, we will have more plastic in the ocean than fish,” said Habib El-Habr to Reuters. She is an expert on marine litter working with the UN environment program in Kenya.According to El-Habr, plastic bags take up to 1,000 years to break down. And through fish and other animals, it can also enter the human food chain. In Nairobi’s slaughterhouses, some cows destined for human consumption had 20 plastic bags removed from their stomachs.Judy Wakhungu, Kenya’s environment minister, said the enforcement of the law would initially be aimed at manufacturers and suppliers of plastic bags, but the law allows police to even go after anyone carrying a plastic bag.
