N2 - Modern intensive agricultural practices characteristic of Western Europe and North America, such as high usage of agro-chemicals, are cited as key drivers of biodiversity declines. Declines in biodiversity are likely to impact on a number of natural processes termed ‘ecosystem services’, which include pollination and pest control that play an important role in agricultural production.
