Is Brexit bad for wildlife?

Just like here, Britain is largely ruled by the EU in relation to environmental law. And, also like here, nature-lovers over there seem to have more confidence in Brussels than in their own legislators when it comes to protecting the environment. Which prompts the question: Would we have any of the natural environment left in Ireland at this stage if we hadn’t so many decades of EU oversight?
The charity Buglife believes a Brexit would pose a significant risk to wildlife conservation and says all sorts of creepy-crawlies — bees, butterflies, ants, beetles, and others — would be better served by remaining in the EU.
