Bright lights, big city: why light pollution threatens migratory birds
October 31, 2018
Migratory birds rely on high quality habitat in which to rest overnight during their annual journeys. However, a recent study suggests that city lights can divert birds from their traditional flight paths. By resting in areas with fewer resources – be it less cover for protection or fewer plants and insects to eat – birds may need more time to complete their migrations and arrive at their destinations in poorer condition.
Water, water nowhere
October 25, 2018
By 2050 two thirds of the world’s population will live in urban areas. This growth will cause an 80% increase in city water demand. To fulfill this growing need for water in cities, water will be taken away from rural and agricultural needs.
Can livestock grazing coexist with plant diversity in Australian rangelands?
October 16, 2018
Across the globe, rangelands are rapidly changing due to human-caused disturbances. New research shows that in Australia, livestock grazing is shifting the balance of plant diversity in favor of non-native species. This could pose serious conservation challenges for Australian rangelands in years to come.
Have your sustainable beef (and eat it too)
October 16, 2018
In the United States alone, beef production accounts for twenty percent of greenhouse gas emissions and it is the least efficient source of protein production. Americans will continue to eat beef; so designing a sustainable industry is essential to reducing emissions. In a new study, scientists explore two straightforward ways to achieve a sustainable industry – all without sacrificing your cheeseburgers.
