from the world's big
Change is coming, but not from the generation that currently holds positions of power.
- With figures like Greta Thunberg and demonstrations like the global climate strike, it's become apparent that young people are driving the effort to stop climate change.
- This generational pressure is the key to change. In the same way that smoking became less accepted in society, even frowned upon, so too can the behaviors that have sped up climate change.
- Moving forward, energy companies will play a major role if they can reimagine themselves as part of the solution to this crisis and forge a better path to save the planet.
Air pollution is up to five times over the EU limit in these Central London hotspots.
- Dirty air is an invisible killer, but an effective one.
- More than 9,000 people die prematurely in London each year due to air pollution, a recent study estimates.
- This map visualizes the worst places to breathe in Central London.

For a number of days, visibility was reduced to as little as one foot, making traffic impossible. The fog even crept indoors, leading to cancellations of theater and film showings. The episode wasn't just disruptive and disturbing, but also deadly. According to one estimate, it directly and indirectly killed up to 12,000 Londoners. <br></p>

ULEZ phases 1 and 2, and LEZ
Image: Transport for London<p>Khan has led a very active campaign for better air quality since his election as London Mayor in 2016. Some of the measures recently decided:</p><ul><li>Transport for London has introduced 2,600 diesel-electric hybrid buses, which is said to reduce emissions by up to 40%.</li><li>Mr Khan has pledged to spend £800 million on air quality over a five-year period.</li><li>Uber fares will rise by 15p (20¢) to help drivers buy electric cars.</li><li>Since the start of 2018, all new single-decker buses are zero-emission and all new taxis must be hybrid or electric.</li><li>Mr Khan has added a T-charge on the most toxic vehicles entering the city. On 8 April, the T-charge will be replaced by an Ultra-Low Emission Zone (ULEZ), contiguous with the Congestion Charge Zone.</li><li>The ULEZ is designed to reduce emissions of nitrogen oxide and particulate matter by charging vehicles who don't meet stringent exhaust emission standards. </li><li>By October 2020, a Low-Emission Zone (LEZ), applicable to heavy commercial vehicles, will cover most of Greater London. </li><li>By October 2021, the ULEZ will expand to cover a greater part of Central London.</li></ul>
Central London's worst places for breathing<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5MjE5Mi9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYzMDUzNTM4MH0.m_JC00WFc9noFCOEsq_17FHZRiVNy89wmC7-0_tOjNg/img.png?width=980" id="47c0e" class="rm-shortcode" data-rm-shortcode-id="b22c53d58d02d17c72c2b0ae5a98507a" data-rm-shortcode-name="rebelmouse-image" />

Traffic congestion on London's Great Portland Street
Image: Mike Malone, CC BY SA 4.0<p>So why is Central London's air pollution problem so persistent? In part, this is because the need for individual transport in cars seems to be inelastic. For example, the Congestion Charge has slashed the number of vehicles entering Central London by 30%, but the number of (CC-exempt) private-hire vehicles entering that zone has quadrupled over the same period.</p><p>Cycling has really taken off in London. But despite all pro-cycling measures, a wide range of other transport options and car-dissuading measures, central London is still a very congested place. Average traffic speeds on weekdays has declined to 8 miles (13 km) per hour – fittingly medieval speeds, as the road network was largely designed in medieval times.</p><p>Narrow streets between high buildings, filled to capacity with slow-moving traffic are a textbook recipe for semi-permanent high levels air pollution. </p><p>The large share of diesel vehicles on London's streets only increases the problem. Diesel vehicles emit lower levels of carbon dioxide (CO2) than petrol cars, which is why their introduction was promoted by European governments.</p><p>However, diesels emit higher levels of the highly toxic nitrogen dioxide (NO2) than initial lab tests indicated. Which is why they're being phased out now.<br></p>

By some measures, London's air quality is almost as bad as New Delhi's.
Image: Sanchit Khanna/Hindustan Times via Getty Images<p>By some measures, especially NO2, London's air pollution is nearly as bad as big Asian cities such as Beijing or New Delhi, and much worse than other developed cities such as New York and Madrid. <br></p><p>The UK is bound to meet pollution limits as set down in the National Air Quality objectives and by EU directives, for example for particulate matter and nitrogen dioxide. </p><ul><li>Particulate matter (PM2.5) consists of tiny particles less than 2.5 micrometres in diameter emitted by combustion engines. Exposure to PM2.5 raises the mortality risk of cardiovascular diseases. The target for PM2.5 by 2020 is 25 µg/m3. All of London currently scores higher, with most areas at double that level.</li><li>Mainly emitted by diesel engines, NO2 irritates the respiratory system and aggravates asthma and other pre-existing conditions. NO2 also reacts with other gases to form acid rain. The limit for NO2 is 40 µg/m3, and NO2 levels must not exceed 200 µg/m3 more than 18 times a year. Last year, London hit that figure before January was over. <span></span></li></ul>

Elephant & Castle, London.
Image: laszlo-photo, CC BY SA 2.0<p>Studies predict London's air pollution will remain above legal limits until 2025. Sadiq Khan – himself an asthma sufferer – is working to make London's air cleaner by measures great and small. Earlier this week, he announced that two of Google's Street View cars will be carrying air quality sensors when mapping the streets of London</p><p>Over the course of a year, the two cars will take air quality readings every 30 metres in order to identify areas of London with dangerous levels of air pollution that might be missed by the network of fixed sensors. An additional 100 of those fixed sensors will be installed near sensitive locations and known pollution hotspots, doubling the network's density.</p><p>It's all part of Breathe London, a scheme to map the British capital's air pollution in real time. Breathe London will be the world's largest air quality monitoring network, said Mr Khan, launching the scheme at Charlotte Sharman Primary School in the London borough of Southwark. </p><p>Up to 30% of the school's pupils are said to be asthma sufferers. Charlotte Sharman is close to Elephant & Castle, as the above map shows, one of Central London's air pollution hotspots.<br></p>
By being someone else, and seeing and discovering the world through the eyes of other people, that can only increase our empathy... and decrease our own egocentric view of the world.
VR could very well be a greater storytelling medium than video games and TV. By being someone else, and seeing and discovering the world through the eyes of other people, that can only increase our empathy... and decrease our own egocentric view of the world. Documentarian Danfung Dennis thinks that virtual reality is an untapped resource that we should keep our eyes on (literally and figuratively), as the right story at the right time could change the world. Imagine a congressman from Texas watching climate change happen at the polar ice caps before their very eyes. It's a powerful prospect. Danfung Dennis is the founder of Condition One, a VR production and technology studio that has created VR experiences for National Geographic, The New York Times, Google, and Hulu.
Environmental concerns have caused some to opt-out of reproduction, both to help the planet and to protect their would-be children.
National Parks have long been a staple of American wildlife conversation. Why not have some underwater?
Awestruck by nature, early American explorers wrote about western landscapes in terms of such singular amazement that residents of the east coast interpreted their accounts to be works of fiction. Since then, national parks and reservations have been established throughout the United States in order, as stated in the so-called Organic Act of 1916, “to conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.” An imperative to preserve natural beauty and diversity runs through much of American history. The benefits of national parks far exceed their profound picaresque appearance: they help to maintain biodiversity and to produce quantities of fresh air that are crucial to our survival. In short, they constitute a wonderful means of preserving ecological stability and splendor.
