Pollution can take many forms.
Air, water, solid waste - most agree that pollution is harmful for people and other life on Earth. But more controversial is how to best prevent it - and clean it up.
We are drowning in plastic! It pollutes our oceans, beaches, rivers and forests. Let's talk solutions. We meet "trash heroes" in Indonesia's Bali who are trying to do away with plastic. The East African country of Kenya was so fed up with its plastic waste, it imposed a ban on plastic bags one year ago. We check in to see how they are faring. And we have more on bioplastics.
There's a broad range of bioplastics. Not all bioplastics are necessarily made from natural renewable materials — at least not completely. We speak to chemical engineering professor Bruce Ramsay who's with Canada's Queens University. Can you walk us through the differences when it comes to non-plastic? Let's maybe start out by explaining the terms bio-based, biodegradable and compostable.
The white sand along Morocco's coast is extremely popular with tourists who come to enjoy scenic walks, soak up the sun and go swimming. One would think. But imagine wading into the water, feeling the salt on your skin, diving under the waves… and swimming into a cluster of plastic waste. Morocco depends on tourism, and yet attempts to implement a new environmental protection regime are flagging.
A video of a diver swimming through a nightmarish soup of plastic bags and food wrappers off the coast of Bali in Indonesia went viral earlier this year, sparking anger and calls for action to tackle ocean pollution. Indonesia is the world's second-largest source of marine plastic waste, after China. Maria Bakkalapulo went to Bali to find out how people there are trying to cut down on plastic.
About one year ago, Kenya introduced one of the toughest plastic bans on the planet: People producing, selling or even using plastic bags now risk being jailed — or face fines of up to tens of thousands of US dollars! Plastic bags used to be very popular at markets, where they were given out for free. So what's the situation like now, one year after the ban was introduced?
Jail for regional politicians defying a court order is being sought by Bavaria's top administrative chamber. Bavaria's government says the judicial "threat" for its failure to tackle Munich's air pollution is "absurd."
