There's very good evidence — again, we don't necessarily have a peer-reviewed methodology that's bulletproof yet — but there's very good evidence that the average cat in Europe has a larger environmental footprint in its lifetime than the average African. You think that's not an issue going forward? You think that's not a question as to how we should be using the Earth's resources?
Hay bastantes pruebas — quizá no tengamos la mejor metodología, contrastada y a prueba de balas — pero hay suficientes pruebas que indican que el gato medio europeo tiene un mayor impacto ecológico durante su vida que el africano medio. ¿No creen que pueda ir a peor? ¿No tendríamos que preguntarnos cómo deberíamos usar los recursos de la Tierra?
