Marine life is fleeing the equator to cooler waters. History tells us this could trigger a mass extinction event

Marine life is fleeing the equator to cooler waters. History tells us this could trigger a mass extinction event
The tropical water at the equator is renowned for having the richest diversity of marine life on Earth, with vibrant coral reefs and large aggregations of tunas, sea turtles, manta rays and whale sharks. The number of marine species naturally tapers off as you head towards the poles. Ecologists have assumed this global pattern has remained stable over recent centuries — until now. Our recent study found the ocean around the equator has already be...

To what extent does climate change affect food insecurity? What we found in Lesotho

To what extent does climate change affect food insecurity? What we found in Lesotho
Food security is a growing concern globally, with two billion people being subject to moderate to severe food insecurity in 2019 according to the United Nation's Food and Agriculture Organisation. Food security consists of four interconnected pillars: food availability (how much is produced), food access (can people afford food), food use (how is food prepared and consumed) and stability (how stable is the food supply and consumption). Large-scal...

New Study Finds Undisclosed Ingredients in Roundup Lethal to Bumblebees

New Study Finds Undisclosed Ingredients in Roundup Lethal to Bumblebees
Researchers found that one of the herbicide formulations killed 96% of the bees within 24 hours. Commonly used herbicides across the U.S. contain highly toxic undisclosed "inert" ingredients that are lethal to bumblebees, according to a new study published Friday in the Journal of Applied Ecology. The study reviewed several herbicide products and found that most contained glyphosate, an ingredient best recognized from Roundup products and the mos...

Collaborative action can secure responsible tuna fisheries

Collaborative action can secure responsible tuna fisheries
Tuna is not only one of the most popular seafoods in the world, it's also a vital part of marine ecosystems.Unfortunately tuna fisheries management prioritizes short-term financial objectives over long-term sustainability.In response, the Global Tuna Alliance has developed the 2025 Pledge towards Sustainable Tuna, to help companies in the supply chain take action. Early in December, the organization responsible for the conservation and management...

5 ways to transform our food system to benefit people and planet

5 ways to transform our food system to benefit people and planet
Globally, we waste a third of all food produced and the natural resources involved in its production;A growing global population requires fairer, more resilient and equitable food systems;Regenerative agriculture, a greater voice for farmers and moving from low cost to "true cost" food can build a stronger food systems for people, planet and the future. Food is essential for our survival, a fundamental requirement of life and the provider of stre...

How technology can help to achieve at least 30% ocean protection

How technology can help to achieve at least 30% ocean protection
A growing number of countries are pledging to protect and conserve at least 30% of the ocean by 2030.Securing such a vast area requires new cutting-edge technology to monitor illegal activities and movements of species.Luckily, this field has been developing fast with new inventions and tech collaborations, writes the Wildlife Conservation Society's Dr. Simon Cripps. It is a dark, stormy night in the South Atlantic. Coastal radar picks up a boat ...

Fermentation can help build a more efficient and sustainable food system – here’s how

Fermentation can help build a more efficient and sustainable food system – here’s how
To meet future demand for protein and ensure food systems are inclusive, efficient and sustainable, we must invest in alternative and plant-based proteins.Fermentation presents an opportunity to fundamentally change the way the world eats and improve global human and environmental health and the economy.Investment in fermentation-derived proteins should focus on achieving the necessary scale and technology. Our global food system is not fit for p...

Track and trace: transparent and digitized fishing data is crucial to ocean resilience

Track and trace: transparent and digitized fishing data is crucial to ocean resilience
Recovery from COVID-19 will require greater transparency in fishing activity.Pandemic has meant surveillance has been suspendedHi-tech innovations offer potential solutions. As the global COVID-19 pandemic continues to unfold, its myriad negative consequences are slowly becoming clearer. While many of the impacts have been unmistakable, with entire countries locked down, some are playing out far away from our homes and shorelines, in the open oce...

Here's how fishing stifles the ocean's ability to capture carbon

Here's how fishing stifles the ocean's ability to capture carbon
When fish die naturally, their bodies and the carbon they contain sink to the depths of the ocean.Yet when fished, this carbon is released into the atmosphere as CO2.As the world has overlooked the ability of fish to act as a natural carbon sink, scientists now estimate carbon emissions from fishing are 25% higher than previously believed. A fish that dies naturally in the ocean sinks to the depths, taking with it all the carbon it contains. Yet,...

Taking fish out of fish feed can make aquaculture a more sustainable food source

Taking fish out of fish feed can make aquaculture a more sustainable food source
The big idea Aquaculture, or fish farming, is the world's fastest-growing food production sector. But the key ingredients in commercial fish feed – fishmeal and fish oil – come from an unsustainable source: small fish, such as anchovies and herring, near the base of ocean food webs. My colleagues and I have developed a high-performing, fish-free aquaculture feed that replaces these traditional ingredients with several types of microalgae – abunda...
