    What is eutrophication?

    What is Eutrophication? It’s a problem that should matter to you, whether you live near the ocean or not. That’s because it begins wherever people live, and ends with damage to resources we all use, and enjoy. It all starts when nutrients get into lakes and oceans. Remember, what’s waste to humans can be food to plants and other creatures. Nutrients feed algae, like they do other plants. Algae grows and blocks sunlight. Plants die without sunlight. Eventually, the algae dies too. Bacteria digest the dead plants, using up remaining oxygen, and giving off carbon dioxide. If they can’t swim away, fish and other wildlife become unhealthy, or die without…

    The problem of light pollution — and 5 ridiculously easy ways to fix it | Kelsey Johnson

    Translator: Ivana Korom Reviewer: Joanna Pietrulewicz Unless you’ve spent quality time on the International Space Station, this is probably not a view you are super familiar with. This is the east coast of the United States. That’s New York down there in the lower right, and it’s a band of light all the way up through Washington DC. Those cities are shining like jewels, highways are traced by webs of light. And all of that light is super photogenic. But there’s a problem. That light is meant to be illuminating our sidewalks, and our streets and our houses. Instead, it’s actually going up into the sky and out into the…

    A breath of fresh air? Parliament’s green watchdog looks at air pollution

    Dr Ben Barratt>>Air pollution in London these days is much better than it was in the 1950’s for example. The major difference is that you can’t see air pollution any more, it’s still there, but it’s of a different nature and it’s now become invisible. Dr Ben Barratt>>The principle source of pollution over London is quite definitely traffic, buses, cars, lorries they all omit pollution that gets dispersed within the city. This pollution is a mixture of gases and particles. Particles are very, very small, so small you can’t see them at all. Dr Ben Barratt>>Unfortunately if you had to design an experimental laboratory for generating and capturing nitrogen dioxide…

    What makes Delhi’s air so deadly

    …near Delhi. The smog here was so thick, drivers couldn’t see where they were going. At least 24 vehicles were damaged as drivers kept crashing into the pileup. These conditions happen every year, when Delhi experiences a huge spike in air pollution. “Are we breathing poison in Delhi?” “…every two minutes one person dies due to air pollution in this country.” “I get nauseous. I get dizzy.” When it hits, the nearly 30 million people here are forced to live in a toxic cloud. Scientists estimate that spending a day outside in these conditions is like smoking 50 cigarettes. “As a lung surgeon, when I open the chest I rarely…
