"The relocation process itself is usually quite complex, bureaucratic, and takes a considerable number of years, considering the difficulty of relocating these concessions to new areas suitable for aquaculture."Matt Craze is the founder of UK and Chile-based Spheric Research, which studies global seafood markets. He says that Chile's salmon industry would invest more money "if they felt that there was a better regulatory framework, and the government gave some certainty about the areas where they can farm".

Data analysed by the BBC show that Ukraine's Western allies have paid Russia more for its hydrocarbons than they have given Ukraine in aid.Campaigners say governments in Europe and North America need to do more to stop Russian oil and gas from fuelling the war with Ukraine.
