Feral pigs are a destructive invasive species across much of North America. In a recent study, forest patches where feral pigs were present had fewer mammal and bird species than swine-free zones.
South Australia has lifted its moratorium on GM crops, while Tasmania has extended its ban. But the question should no longer be a simple binary of being “for” or “against” GM technology.
It’s unlikely that all species of bees will go extinct anytime soon – but current losses could still have a terrible impact on food supplies and ecosystems.
A new report calls land key to solving climate change. The good news is that there are strategies for reducing carbon emissions from land use that can also produce economic and social benefits.
A new IPCC report has called for radical changes in food production to avoid catastrophic climate change. Rice-fish farming and mixed crops could help.

Millions of Americans rely on groundwater for their lives and livelihoods, but regulation is piecemeal. A new study maps groundwater wells nationwide and finds that they are drilling steadily deeper.
South Africa’s recently introduced carbon tax may lead to financial losses in the short term, but it’s necessary and will be beneficial in the long term.
Scientists are predicting major algae blooms in Lake Erie and large dead zones in the Chesapeake Bay and Gulf of Mexico this summer. Nutrient pollution from industrial corn farming is a major driver.
Western states adopted a 7-year plan in May 2019 to manage low water levels in the Colorado River. Now they need to look farther ahead and accept that there will be less water far into the future.
As climate change alters temperature and rainfall patterns, yields of some crops are increasing while others decline. The net result: less food, especially where it’s most needed.
