Planting more trees won’t roll back climate change
If we continue burning coal and oil the way we do today and regret our inaction later, the amounts of greenhouse gas we would need to take out of the atmosphere in order to stabilize the climate would be too
Fresh versus frozen: a sustainable choice with a twist
The optimization of transportation footprints, batch sizes, temperatures and storage times may greatly lower the impact of frozen food on the environment.
Breeding cows that are resistant to climate change
Some scientists from the University of Florida in the US are breeding what they call the “cow of the future”: a bovine that is far more tolerant of increased heat.
