Interesante perplejidad. Aventuro que para ese niño, Winnie no es ni blanco ni negro: es Winnie, tal como es. Cuando convives el tiempo suficiente con alguien el tiempo suficiente, el color de su piel se vuelve transparente: aparece la persona. Lo mismo digo para cualquier otro rasgo físico que nos sorprenda al primer golpe de vista.

La mundialización nos ofrece la oportunidad de trascender la visión de campanario. El trato con individuos de otras razas nos cura de la perspectiva pueblerina (“en mi pueblo somos así”).

CARBON DIOXIDE is the main greenhouse gas emitted by human activities. But it is not the only gas capable of causing great harm to people and the planet. That point was driven home by the emissions scandal that engulfed Volkswagen last year. Since the 1990s policymakers in Europe had backed diesel as a way to reduce carbon emissions, turning a blind eye to other ways in which the fuel might damage human health. The VW affair drew back the veil on this trade-off. The company’s diesel engines did indeed deliver lower carbon emissions and better fuel economy, but at the cost of belching out noxious pollutants capable of shortening many lives.

A similar case of **tunnel vision** also exists in the energy industry. To its evangelists, natural gas helps satisfy demand for fossil fuels but causes less harm to the planet than coal and oil. Like diesel carmakers, natural-gas producers make reduction of carbon-dioxide emissions a big selling-point, but downplay the effects of other gases they emit. For the car industry, the problem is nitrogen oxides. For natural gas, it is methane, the fuel’s main component.
