he tiny polyphagous shot hole borer and its associated fungus looks set to become the most damaging biological invasion in South Africa’s urban environments, warns the country’s latest report on biological invasions.

Scientists around the world are looking for ways to remove carbon dioxide from the atmosphere. This gas is a natural component of the atmosphere, released by processes of respiration and decomposition of organic matter.

Older, large-diameter trees have been shown to store disproportionally massive amounts of carbon compared to smaller trees, highlighting their importance in mitigating climate change, according to a new study in Frontiers in Forests and Global Change.

The challenges agriculture poses are well known.

Over the past decade-and-a-half, industrial agriculture has caused almost one-third of global forest loss–all of which is permanent, finds a new Science paper. It’s the first study to weigh up the impacts of different forest loss drivers, and while its findings are sobering, they could also go a long towards increasing transparency in the supply chains of major global foods.

The problem isn’t just that many forests are being lost. It’s also that many remaining forests are getting younger.
