Britain bans gasoline and diesel cars starting in 2040



      Britain will ban sales of new gasoline and diesel cars starting in 2040 as part of a bid to clean up the country’s air. The decision to phase out the internal combustion engine heralds a new era of low-emission technologies with major implications for the auto industry, society and the environment. “We can’t carry on with diesel and petrol cars”, U.K. environment secretary Michael Gove told the BBC on Wednesday. “There is no alternative to embracing new technology”. Almost 2.7 million new cars were registered in the U.K. in 2016, making it the second biggest market in Europe after Germany.
      Meeting the 2040 deadline will be a heavy lift. British demand for electric and fuel cell cars, as well as plug-in hybrids, grew 40% in 2015, but they only accounted for less than 3% of the market. Still, experts say sales of clean cars are likely to continue on their dramatic upward trajectory.
      The car industry says that demand for electric vehicles will only reach a tipping point once they're cheaper to own than conventional vehicles.
      The deadline was announced by the government on Wednesday as part of a plan to reduce air pollution. The blueprint highlighted roughly £1.4 billion in government investment designed to help ensure that every vehicle on the road in Britain produces zero emissions by 2050.
     Gove said action was needed because gasoline and diesel engines contribute to health problems, “accelerate climate change, do damage to the planet and the next generation”. Roughly 40,000 deaths in Britain each year are attributable to outdoor air pollution, according to a study published last year by the Royal College of Physicians. Dirty air has been linked to cancer, asthma, stroke and heart disease, among other health issues.
     The problem is especially pronounced in big cities. London surpassed the European Union’s annual limit for nitrogen dioxide exposure just five days into the new year, according to King’s College. The university estimates that air pollution is responsible for 9,400 premature deaths in the city every year.
     The timeline for ending sales of internal combustion engines mirrors one proposed in early July by France. President Emmanuel Macron has given the auto industry the same deadline to make the switch to cleaner tech.
     “We are quite rightly in a position of global leadership when it comes to shaping new technology”, Gove said. But the auto industry, which supports over 800,000 jobs in the U.K., is wary of hard deadlines.
     Other countries have been even more ambitious than the U.K. India is planning to stop selling gas-powered vehicles by 2030.
      The German car industry and government officials will meet in early August to discuss the future of diesel engine technology. Manufacturers are trying to avoid diesel cars being banned from German towns and cities. 
Consider the following excerpt taken from the text:

British demand for electric and fuel cell cars, as well as plug-in hybrids, grew 40% in 2015, but they only accounted for less than 3% of the market.

Difficulty interpreting what I have come to call ‘Ahorita Time’ is a reflection of different cultural understandings of time.

In the UK or the US, however, “The audience starts to leave, feeling like I am wasting their time”.

The ways Mexicans tell time


Understanding this takes not a fluency in the language but rather a fluency in Mexican culture.

Mexicans are famous in the Spanish-speaking world for their extensive use of the diminutive. While in most Spanish-speaking countries the addition of the diminutive ‘ita’ to an adverb like ahora (meaning ‘now’) would strengthen it to indicate immediacy (i.e. ‘right now’), this is not the case in Mexico. Dr Company explained that Mexicans instead use the diminutive form to break down the space between the speaker and the listener and lessen formality. In this case of ‘ahorita’, the addition of the diminutive reduces urgency rather than increasing it – a difference that can be extremely confusing for foreigners.

Alguns aplicativos instalados em dispositivos móveis permitem que mapas digitais e imagens de satélite sejam utilizados para encontrar caminhos, locais de interesse, desvios e alertas de acidentes, de fiscalização ou até mesmo de trânsito intenso. A informação georreferenciada é cada vez mais comum também em apps que oferecem produtos, serviços e relacionamentos sociais. [...] Atualmente encontram-se em funcionamento os sistemas de navegação por satélite norte-americano (GPS) e russo (GLONASS), e estão parcialmente implantados os projetos de navegação por satélite europeu (GALILEO), chinês (COMPASS ou BeiDou-2) e, mais recentemente, o japonês (MICHIBIKI).
A respeito da tecnologia de navegação por satélite, considere as seguintes afirmativas:

1. É a mais importante fonte de dados de navegação terrestre, pois fornece tanto a posição geográfica quanto a atualização da base de dados geográficos dos aparelhos celulares (arruamento, pontos de interesse, direções de vias, entre outros).
2. A informação enviada pelos satélites até o aparelho receptor (smartphone ou tablet, por exemplo) se propaga por ondas eletromagnéticas e independe da existência de rede de internet.
3. A existência de várias constelações artificiais de sistemas de posicionamento por satélites tende a tornar o sistema impreciso, devido às interferências entre os sinais emitidos pelos diferentes satélites.
