How air pollution is making life tougher for bugs

Envirotec Magazine

Over a span of two years, we artificially elevated the levels of either ozone or diesel exhaust fumes around plots of flowering black mustard plants, all within fields of non-flowering wheat. Air pollutants like ozone are highly reactive and can degrade the signals by destroying the chemicals that make up a flower’s scent.

Gas purification converts NOx to fertilizer

Envirotec Magazine

The firm says this binds nitrogen oxides efficiently so that they can be collected with little effort and then used to produce fertilizers for agriculture. Not only are they a significant source of air pollution, but they also contribute to climate change via their conversion into ozone.

To Meet Sustainability Goals, Food Companies Need To Slash Methane

EDF + Business

While some food and agricultural companies are making progress on methane, there’s still a long way to go. Food and agricultural companies are especially vulnerable to climate change risks, given increases in extreme and volatile weather, which can impact their productivity as well as their long-term resilience.
