Oak processionary posed a health threat. In April 2018, an outbreak of the caterpillars was reported across Greater London and surrounding areas. The moth is now fairly common in Belgium, notably in the Campine but also elsewhere, with fluctuating population numbers from year to year. In 2007 infestations in the Belgian province of Limburg were so acute that soldiers were deployed to burn them. In the Netherlands, the caterpillars are dealt with by biological pest control. Local authorities use, like in Germany, fluids containing bacteria that are toxic only to the caterpillars. These fluids are sprayed onto the infected trees. Furthermore, an
Animal (De)liberation should be banned. The position that Deckers adopts is unusual in that he argues that this question must be resolved by addressing the question of what is optimal for human health, where Deckers argues for an unconditional duty to maximise positive global health impacts, which is tantamount to a duty to minimise negative global health impacts. Applied to the consumption of animal products, this duty transpires into the duty to commit to qualified moral veganism: vegan diets ought to be the default diets for the majority of the human population. In the first chapter, Deckers abstracts from some of the
