There is another big difference between land-based and sea-based environmental degradation. The sea is a place where the ancient human activity of hunting and gathering continues, and continues apace. As has just been pointed out by my hon. Friend the Member for Great Grimsby (Melanie Onn), other human activity, such as the use of plastics, has its impacts, but much of it is invisible. Man-made climate change is leading to the warming and acidification of our oceans, with yet unknown consequences. It does not affect just marine life—including fish, as an edible resource—but the roles that the oceans themselves play in regulating our climate, our oxygen levels, and basically everything that makes human life on earth possible.
