Reacting to the vote to leave the EU, Greenpeace UK executive director John Sauven said:
"Many of the laws that make our drinking and bathing water safe, our air cleaner, our fishing industry more sustainable and our climate safer now hang by a thread. But Greenpeace is determined that this country does not go back to year zero on environmental protection.
"Over the coming months we all need to demand that the government replaces European regulations protecting nature with new UK laws that are just as strong.
"There is a very real fear that Cameron's successor will come from the school that supports a bonfire of anti-pollution protections. The climate change-denying wing of the Conservative Party will be strengthened by this vote for Brexit. That means the green movement, indeed every Briton who values a clean and safe environment, may need to stand up for nature in the face of an attack on the natural world.
"The environment barely featured in this campaign. Whoever comes to occupy Downing Street does not have a mandate to gut the environmental laws that we all rely on to protect us from pollution."
