If you listened to Costing the Earth on Radio 4 this afternoon, you will have caught an interesting program about the environmental problem of plastics, together with some creative solutions to those problems. Right at the end of the programme, there was a discussion about whether plastics and fuels produced from plants are a viable alternative to ones produced from fossil oil. The conclusion was that they are not.
Plastic production is one of the biggest sources of greenhouse gas emissions. What’s more, plastics themselves make up a huge amount of our waste and hang around taking-up masses of space in landfill for a very, very long time indeed. So, there’s a pressing need to use less plastic created from fossil fuels.
Why then did the academic interviewed at the end of the programme claim that plant-based biodegradable plastics are not a viable alternative to fossil-fuel-based plastics? The reason he gave is that the amount of meat in diets is increasing, which in turn requires more land to grow food crops for the animals we are eating. Because of this, he argued, we can’t afford to give up agricultural land to grow plants for plastic production or bio-fuels.
It’s true that the amount of land required to sustain diets including meat is much greater than what’s required for a vegetarian/vegan diet (and much more environmentally damaging). But the alternative solution he proposed to the plastic problem shocked me because of the lack of how badly he’d failed to think about the issue critically.
His argument was that rather than grow crops for plastic and fuel production, which is we can’t do because we are using the land for meat production, we should use less plastic.
Well, of course we should use less plastic! But one wonders how he didn’t also conclude that we should also eat less meat? In fact, it looks likely that it’s more efficient to eat less meat than use less plastic! If we ate less meat we would have lots more land available for growing biofuels and creating biodegradable plant-plastics. What’s more, the pressure on land would be less, so the chance of sustainable biofuels being grown would be higher (biofuels are often currently being produced in environmentally damaging ways because of the pressure on land use).
It’s quite sad that the (ab)use of animals is so embedded in our culture that clever, educated people cannot even contemplate not eating meat, even when doing so is a really obvious solution to an incredibly serious threat to us all.
