  • 'Green'-feed: Industrial microbes could feed cattle, pigs, chicken
    on June 20, 2018 at 1:48 pm

    Today, producing feed for pigs, cattle and chicken causes immense impacts for the climate and the environment. In the future, animal feed production is likely to be shifted from croplands to large-scale industrial facilities as it could bring both financial and environmental benefits. Replacing 2 percent feed with protein-rich microbes could decrease agricultural greenhouse gas emissions, global cropland area and nitrogen losses by over 5 percent. […]

  • Light pollution a reason for insect decline
    on June 19, 2018 at 4:24 pm

    Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Scientists have now discovered that regions that have experienced a sharp decline in flying insects also have high levels of light pollution. Many studies already suggest that artificial light at night has negative impacts on insects, and scientists should pay greater attention to this factor when exploring the causes of insect population declines in the future. […]
