Se comer carne, não dirija

Se vocês voltarem ao post sobre Pesquisas inúteis verão que Aldina comentou sobre o papel do gado sobre o efeito estufa. Recebi também comentários, sobre o mesmo aspecto, de Isaac Roitmann e Luiz Hildebrando por e-mensagem. Achei que o tema merecia ser tratado separado de apenas comentários num post sobre aumento de BMI (body mass index).

O artigo Cows Blamed For Greenhouse Effect diz:

“While CO2 emissions have increased by 31% during the past 250 years, methane, which has a higher warming potential and a longer lifetime in the atmosphere, has increased by 149% during the same period, he added.

Methane in the atmosphere was believed to be responsible for one-fifth of global warming experienced since 1750, he pointed out.”

Numa comparação interessante:

“Two hundred cows burp the annual equivalent amount of methane to the energy produced by a family car being driven 111,850 miles, said Dr Andy Thorpe.

The economist, from the University of Portsmouth, explained that the amount of methane produced by a herd was the same as the carbon dioxide (CO2) emissions produced by a car burning 21,400 litres of petrol.”

Assim, para preservar o meio ambiente devemos fazer uma adição às recomendações contidas no post de Camila:

Se comer carne, não dirija.
