As the population gets bigger and people get wealthier, meat consumption is forecasted to increase. Florian was able to calculate the environmental costs if some of this projected meat consumption was gradually replaced by people eating microbial protein. He looked at a few senarios to see what would happen if 20 % of meat were substituted, or if 50%. As meat consumption decreases, there's less need to cut down forest to make new pastures. The study also acquired some deforestation and emissions from homangis change.
00:46 How a move to microbial protein could affect emissions
It’s well understood that the production of meat has large impacts on the environment. This week, a team show that replacing 20% of future meat consumption with protein derived from microbes could reduce associated emissions and halve deforestation rates.
How saltwater crocodiles’ penchant for pigs is driving population recovery in Australia, and solving the mystery of some eighteenth-century porcelain’s iridescent lustre.
10:47 The neurons that help mosquitoes distinguish smell
Female Aedes aegypti mosquitoes strongly prefer human odours to those of animals, but how they distinguish between them is not well understood. Now, researchers have shown that human odours strongly activate a specific area in the brains of these insects, a finding that could have important implications for mosquito-control strategies.
We discuss some highlights from the Nature Briefing. This time, how climate change could affect virus transmission between mammals, and how the link between a dog's breed and its temperament may not be as close as previously thought.
