  2. Today, nitrogen pollution is one of the most pressing pollution issues facing humanity, threatening our environment, health, climate and ecosystems. Countries must step up their joint efforts to reduce nitrogen waste by 2030.

  3. Jan 16, 2023 · Here are four reasons why humanity needs to limit nitrogen pollution. 1. Nitrogen pollution is disrupting life on land and underwater. When the availability of nitrogen compounds exceeds consumption by plants, excess nitrogen gets into the environment, often filtering into aquatic ecosystems.

    Sep 28, 2023 · Nitrogen pollution contributes to the triple planetary crisis of climate change, nature and biodiversity loss, and pollution and waste. Today, about 80 per cent of reactive nitrogen – estimated to be worth US$200 billion – is lost to the environment every year.

    The struggle to provide, or “fix,” enough nitrogen in soil to grow bountiful crops has been a constant of human history. Both nitrogen and phosphorus are necessary components of photosynthesis; without enough, plants turn sickly and stunted. Nitrogen is naturally abundant, making up 80% of the atmosphere, but most plants can’t use it until it’s con...

    Before the advent of synthetic fertilizers and fossil fuels, the movement of nitrogen through the biosphere was relatively stable. In what’s known as the “nitrogen cycle,” the element’s atoms traveled through flora and fauna, being released via excretion and death back into the ground, with some escaping through bacterial conversion to the atmosphe...

    Across the planet, people whose livelihoods depend on lakes and oceans are bearing the brunt of the worsening crisis. For decades now, shrimpers who fish the Gulf of Mexico have borne the cost of one of the biggest marine “dead zones” in the world, with agricultural runoff traveling to the Gulf from the Midwest via the Mississippi River causing an ...

    Sutton says a key problem blocking global action is what he calls “fragmentation” of efforts to address nitrogen pollution by policymakers. Agricultural runoff isn’t the only way that nitrogen is being pumped into the biosphere. It’s also released into the atmosphere as nitric oxide when fossil fuels are burned, and is also converted into another g...

    As with the other planetary boundaries, policymakers have been slow to grasp the potentially catastrophic impacts of nitrogen and phosphorus pollution. Those who have begun to recognize the scale of the problem are finding there are few palatable approaches to it. As with fossil fuel companies, industrial agribusiness wields immense political and e...

    In 2018, a group of scientists released a studyanalyzing satellite images for 71 of the world’s lakes. The results were consistent across regions: More than half showed evidence of algae blooms, and they were getting worse. The few lakes that showed signs of recovery were primarily those that had also experienced a reduction in atmospheric temperat...

  5. This article explores how nitrogen becomes available to organisms and what changes in nitrogen levels as a result of human activity means to local and global ecosystems.

  6. Dec 4, 2016 · From farm to fork. One way to understand our nitrogen use is to look at our nitrogen footprint – the amount of nitrogen pollution released to the environment from food, housing,...

  7. Jan 22, 2021 · By massively increasing the supply of nitrogen compounds, humans are worsening air and water quality, contributing to climate change and stratospheric ozone depletion, and thereby threatening health, biodiversity, and livelihoods.
