Are you thinking about Newton’s laws like F=MA and wondering if the wave is moving the earth on some scale? You might have already answered yourself because for every action there’s the equal and opposite reaction. The energy going into the sand is roughly equal in magnitude to the energy that got sent back into the sea. The waves and sand erosion you see are the manifestations of the energy bouncing around in this system as it finds homeostasis.
The models get 0% of the proceeds for one year and then 10% after that. After interviews and photos of the models, they get around to interviewing the CEOs of the companies doing this, and there’s an unchallenged narrative about why it’s fair and not exploitative. Shame on the BBC.
