A market that lets sugar cane farmers trade ‘nitrogen permits’ could help keep a cap on fertiliser use.
You've heard of cap-and-trade schemes for greenhouse gases. Perhaps we also need one to limit the amount of fertiliser runoff onto the Great Barrier Reef.
Climate change is warming Lake Tahoe and could alter its chemistry in harmful ways.
Lakes contain most of the fresh water on Earth's surface. Recent research at Lake Tahoe in the Sierra Nevada mountains shows that climate change could alter lake chemistry, threatening these sources.
Fixing water pollution on the Great Barrier Reef will take a huge effort.

Efforts to combat water pollution on the Great Barrier Reef aren't working, according to a new government report.
Fertilizer runoff and other activities have 60 percent of Chesapeake Bay in a virtual dead zone.

In its first environmental case post-Scalia, the Supreme Court rebuffs farm and ranching interests that opposed the EPA's multistate plan to restore Chesapeake Bay using the Clean Water Act.
Lead can linger in bones.

Lead might not be in paint or gasoline anymore, but since it doesn't break down in the home or the environment it remains a problem throughout the U.S.
A child collects clean water in Delmas, east of Johannesburg, an area vulnerable to outbreaks of the deadly typhoid virus.
The danger with typhoid is that symptoms are quite insidious and mimic those of other infectious diseases.
Pregnant women in three Australian cities are not told that lead exposure during pregnancy is linked to miscarriage and early delivery.
Parents in three Australian states are being given misleading advice about the dangers of lead to babies and small children – including failing to warn pregnant women about miscarriage risks.
Nutrient runoff is one of the major contributors to crown-of-thorns outbreaks.

Despite 15 years of concerted action by the Australian and Queensland governments the health of the reef is not improving and in fact may be continuing to deteriorate.
Nitrogen pollution is one of the factors driving outbreaks of crown-of-thorns - giant starfish that devour the reef.

The latest Great Barrier Reef report shows some improvements to water quality over the past five years, but there's still a lot to do on one particular problem: nitrogen.
More than thirty chemicals can go down the drain from products we use everyday.

The simple act of shampooing and conditioning our hair, even with green products, results in more than 30 chemicals being washed into our sewers.
Lots of these: settling ponds precipitate iron oxide and other suspended materials from the Red and Bonita mines near the Gold King Mine.
Newly released data show how the hundreds of abandoned mines in the western US discharge the same volume as the Gold King Mine spill every two days.
Waterbugs are used for the monitoring of river ecosystem health across the world.
Around the world, waterbugs are the most widely-used indicator of environmental health and pollution of rivers, lakes and wetlands.
The Curtis Island gas precinct is one of the biggest developments along the Great Barrier Reef coast.
The coast alongside the Great Barrier Reef is home to ports, farms, holiday resorts, and more than a million people. It all puts pressure on the Reef, and it's time for some firms plans to manage it.
Rainwater + hard urban surfaces = lots of runoff.
Built-up urban environments transform the resource of rainwater into wasted runoff. Low Impact Development mimics nature to help get stormwater into the natural water system.
Antibiotics from both human and animal use end up in our waterways.
We are only beginning to recognise the growing problem of antibiotics polluting our environment, and the serious repercussions it has for health.
One Nation’s Pauline Hanson says landholders’ constitutional water rights have been undermined by government changes – but is that true?

Rubbish strewn on beaches eventually ends up in one of the world’s giant ocean garbage patches.
Most of us have littered at one time or another, and in the process we probably contributed to the enormous of amounts of plastic that enter the ocean every year, eventually ending up in one of the five…
