Today the Prime Minister announced an expansion of our Marine Protection Zone around our overseas territories.
The island of Tristan da Cunha is the latest to introduce a protection zone closing 90% of its waters to human activity.
This brings the total of UK waters protected to 4.3million sq km - approx 1% of the oceans, a size equivalent to 14 times the size of the UK.
Boris Johnson is urging other nations to follow suit with an aim to protect 30% of the worlds oceans by 2030.
Marine protection zones allow depleted species to recover, the waters to be cleaned up and important fish stocks to recover.
This is great news and a step forward in protecting the planet and reducing the impact of climate change
