Mas Londres já foi, em outras épocas, uma cidade muito poluída, justamente pelo uso de carvao para aquecimento, o que foi abandonado posteriormente.
China e Índia fazem uso intensivo de carvao, tanto para aquecimento doméstyico, como para fins energéticos e industriais, e o pior é que se trata de carvao de péssima qualidade.
Nao espanta, assim, essa situacao terrivel, que eu já contemplei pessoalmente, da janela do trem, de Shanghai a Beijing: passamos por cidades onde era impossível distinguir qualquer coisa, tal a quantidade de smog no ar. Tudo cinzento.
O custo humano é terrível.
Esses sao os nossos aliados no BRICS...

“Crazy bad” air pollution – in pictures
A picture is worth a thousand words. And China’s extreme air pollution problem – now “beyond crazy bad” as one blogger put it, really needs to be seen to be believed.
In that spirit, beyondbrics has put together some images of the toxic smog that has hit swathe of northern China this month, causing flights to cancel, prompting runs on air purifiers and face masks and even inspiring one entrepreneur to sell fresh air in a can.
Tiananmen Square – with toxic smog….
…and sans smog
Good to see someone in the government has a sense of humour.
Residents can take comfort in being able to LOOK at TV images of a blue
sky.
Because there’s not not much blue sky to be found here….
or here….
That last photo? That’s supposed to be a view of the Forbidden City. Below, sans smog.
Can’t blame people for stocking up on masks and air purifiers. What
next? People walking around with gas masks and carrying oxygen tanks?
One entrepreneur doesn’t think that’s so far fetched.
Chen Guangbiao, a philanthropist and one of China’s richest man, has
started selling “canned fresh air” (pictured below) for RMB 5 ($0.80)
each as a tongue in cheek protest over China’s air quality. The air is
purportedly from far-flung and pristine regions of Tibet and Taiwan.

Rain helps clear the air a little in Beijing
Source: Xinhua
Shanghai Daily, February 1, 2013
THE heavy smog that has choked Beijing for the past five days
weakened slightly yesterday due to rain, although the capital's air
remained heavily polluted.
A little rain fell overnight on Wednesday, the Beijing Meteorological Bureau said. The air quality index fell but was still above 200, or seriously polluted.
Earlier this week, Beijing implement stricter measures to reduce pollutants, including suspending the use of 30 percent of local government vehicles and halting production at 103 heavily polluting companies.
But not everyone abided by the measures. More than 800 government vehicles supposed to be suspended were still in use, municipal traffic authorities said.
And several construction sites ordered to suspend their work failed to do so on Wednesday.
In many other parts of north and east China, smog has disrupted flights and traffic.
Thirty flights were canceled and 78 flights were delayed yesterday morning at an airport in Tianjin, just east of Beijing.
Visibility was reduced to less than 50 meters in many parts of east China's Shandong Province.
However, the National Meteorological Center rescinded its yellow smog alert early yesterday with smog in central and east China expected to be dispersed by a cold front due today.

Um breve e ponderado texto sobre o uso de usinas de carvão.
ResponderExcluir"Eleito pelos verdes o inimigo número um da humanidade, o carvão, de acordo com Mary J. Hutzler, do Instituto de Pesquisas Energéticas dos Estados Unidos, é o combustível fóssil mais abundante do mundo, utilizado como fonte de energia na indústria de base para a produção de aço, de cimento e de papel, bem como em outras indústrias. (...) Graças ao desenvolvimento tecnológico, as novas usinas de carvão são muito menos poluentes do que as antigas. Diversos países do mundo, dada a abundância deste combustível e seu preço barato, têm investido na construção dessas modernas usinas, China à frente. Só para se ter uma ideia, desde 1980 as emissões totais de poluentes, de acordo com os seis critérios utilizados pela agência do meio ambiente americana, caíram nada menos que 63%, apesar de o consumo de carvão nos EUA haver quase dobrado no mesmo período. O ser humano e, principalmente, os países pobres não podem se dar ao luxo de jogar fora uma fonte de energia tão barata e abundante." (JOÃO LUIZ MAUAD)
