I want to ask about the wider environmental impact. My hon. Friend will know that 4G has the same carbon footprint as all of aviation, and 5G will be a lot more. What is more, we are now hearing that 5G will have a detrimental impact on insect life, which is decreasing globally at 2.5% per year. Given that insects are essential to humanity because they are required to pollinate all fruits and vegetables, does she agree that before hurtling ahead for commercial reasons, we should apply the precautionary principle until we know precisely what the impact will be on insects and our carbon footprint?
