Uma grande empresa brasileira de petróleo está mostrando um comercial em que diz “Zeramos nosso Footprint”. Quantas pessoas entenderiam isso? Por que não dizer isso em “Plain Portuguese”? Se fosse um relatório para a diretoria... mas, um comercial de televisão? A propósito, como esse termo poderia ser traduzido? Pegadas Ecológicas? Índice de Danos Ambientais? Rastro Ambiental?
The ecological footprint is a measure of human demand on the Earth's ecosystems. It compares human demand with planet Earth's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Using this assessment, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle. For 2005, humanity's total ecological footprint was estimated at 1.3 planet Earths - in other words, humanity uses ecological services 1.3 times as fast as Earth can renew them. Every year, this number is recalculated - with a three year lag due to the time it takes for the UN to collect and publish all the underlying statistics.hile the term ecological footprint is widely used, methods of measurement vary. However, calculation standards are now emerging to make results more comparable and consistent.
