The moral theories behind climate deadlock

I recently stumbled across a very unsettling video. A man was about to eat an apple. He was ready to wash it with tap water only to realise that the water would make the apple dirtier than it was before. He grabbed some filtered water from a plastic bottle only to realise that it was filled with microplastics that would contaminate the apple too. He then thought of growing apples in his backyard. But the soil is no longer rich in the nutrients that make apples nourishing.
