Arthur C Clarke | Vegan tropes | Hadrian’s Wall | Honoured Liverpool FC players | Morris MinorsAs with so many things, Arthur C Clarke foresaw the contamination of other worlds (Letters, 14 June) in his short story Before Eden, published in Amazing (June 1961), which relates the arrival and departure of an Earth spaceship to Venus, and its consequences. He also foresaw the rise of internet pornography in I Remember Babylon, published in Playboy (March 1960).

• How sad that Dave Collins (Letters, 13 June) felt the need to trot out the trope about vegans and meat-free versions of sausages and burgers. It’s the animal cruelty inherent in the consumption of meat that we abhor. We’ll eat our plant-based diet in whatever form we choose, thanks. And if we want to get more youngsters to sit at the vegan then “fake” bangers and burgers offer a great introduction.
