We know our oceans and coastlines are choking on plastic. We've all seen plastic bottles, food wrappers and plastic bags polluting beaches, and been horrified by the stories of marine creatures like seabirds and whales starving when their stomachs become packed full of plastic.
Scientists have shown that up to 12 million tonnes of plastic is entering our oceans every year—that's a rubbish truck full every minute. Single-use plastic packaging for food and drink is a particularly common part of the problem.
But how does plastic actually get into our oceans?
While about a fifth of marine litter is made up of fishing gear and other materials lost at sea by accident, industrial losses or illegal dumping, we know that roughly 80 percent of litter in the seas comes from land.
The sheer amount of plastic that has been generated in the past 60 years is mind boggling. New research shows that we've produced plastic as heavy as 1 billion elephants since the 1950s. Even more staggering is the amount that has rapidly become waste. Just 9 percent of this plastic has been recycled. That means the majority of plastic waste has simply been dumped in landfills or burned.
However, when plastic waste is collected and transported to landfill sites, it can be at risk of escaping into the environment. Even when it's in landfills, plastic is at risk of blowing away and ending up in rivers or oceans.
Even more of a risk is plastic litter. That's plastic that either that isn't collected where good waste managements systems are lacking, or plastic that is simply dropped or left behind on streets or in the environment. These plastic items can be carried by wind and rain into our drainage networks or rivers that then flow into the sea. Major rivers around the world carry an estimated 1.15 — 2.41 million tons of plastic into the sea every year—that's up to 100,000 rubbish trucks.
Holiday-makers visiting beaches and leaving behind their bottles, food packaging and cigarette butts on the sand directly contribute to plastic getting into the ocean. Ironically, the tourism industry that has enabled more people to visit beautiful beaches is suffering as the growing problem of plastic pollution is turning visitors off destinations where the problem is most visible.
Products That Do Down the Drain
Many people were horrified to discover that tiny pieces of plastic known as microbeads have been added to all sorts of personal care and cosmetic products that are washed directly down the drain—from face scrubs to shower gels to toothpaste. As many of these microbeads are too small to be filtered out by wastewater plants, these plastic pieces are remaining in water that may end up flowing into the ocean.
That public outrage at these microbeads polluting our oceans combined with concerted campaigning has led to governments across the world banning products from containing microbeads, including the UK, U.S. and Canada.
But plastic in cotton buds, face wipes or sanitary products that are flushed down the loo, and even plastic fibers in clothing that shed in the washing machines still pose a risk for plastic entering the ocean.
Finally, lax standards in industrial processes are responsible for some plastic getting into the environment, either when products containing plastic aren't disposed of properly, or escaping during the production and or transporting of products. For example, thousands of the tiny plastic pellets used to make plastic products, known as nurdles or mermaid's tears, are washed up on UK shorelines every year, polluting nearly three quarters of UK beaches at a count in February this year.
Once plastic is in our oceans, it flows on ocean currents all across the world—so even uninhabited islands in the Pacific and the Arctic are becoming dumping grounds for plastic.
That's why we have to tackle the problem at source. To end ocean plastics we need corporates to reduce the amount of single-use plastic they are selling, to cut down on the plastic that is thrown away in the first place. We also need governments to improve waste management systems and boost the re-use of plastic through initiatives that boost resource efficiency and a circular economy. We need to close the loop on plastic, ensuring it stops escaping into our environment and flowing into the oceans. Marine life simply cannot stomach any more plastic.

Late fall, after the last crops have been harvested, is a time to rest and reflect on the successes and challenges of the gardening year. But for those whose need to putter around in the garden doesn't end when cold weather comes, there's surely a few lingering chores. Get them done now and you'll be ahead of the game in spring.

If you had to choose a diamond for your engagement ring from below or above the ground, which would you pick … and why would you pick it? This is the main question consumers are facing when picking out their diamond engagement ring today. With a dramatic increase in demand for conflict-free lab-grown diamonds, the diamond industry is shifting right before our eyes.

The Pacific Island nation of Samoa declared a state of emergency this week, closed all of its schools and limited the number of public gatherings allowed after a measles outbreak has swept across the country of just 200,000 people, according to Reuters.

Rising above the Arizona desert, the Santa Rita Mountains cradle 10,000 years of Indigenous history. The Tohono O'odham Nation, Pascua Yaqui Tribe, and Hopi Tribe, among numerous other tribes, have worshipped, foraged, hunted and laid their ancestors to rest in the mountains for generations.
Native Americans are disproportionately without access to clean water, according to a new report, "Closing the Water Access Gap in the United States: A National Action Plan," to be released this afternoon, which shows that more than two million Americans do not have access to access to running water, indoor plumbing or wastewater services.

In the Czech Republic, horses have become the knights in shining armor. A study published in the Journal for Nature Conservation suggests that returning feral horses to grasslands in Podyjí National Park could help boost the numbers of several threatened butterfly species.
