Kelp forests around the world, and in Canada, are under threat. New research sheds further light on the health, and resilience, of these crucial ecosystems.
Kelp seaweed spores are being grown on small rocks and waste scallop shells as part of a trial exploring how to regenerate the UK’s coastal kelp forests.
Cattle are major producers of methane, a potent greenhouse gas. But there are methods that can reduce their climate impact – if ranchers have incentive to use them.
Instead of supporting Indonesia’s seaweed industry, an export ban could lower prices and reduce supply, without helping domestic processors to compete with foreign-owned companies.
Over 200 million tonnes of sediment are transported by rivers to the sea each year, the most widespread water contaminant in the country. Its devastating impact on marine life has to be reversed.
To fight global warming we will soon have to try to remove carbon dioxide from the skies or find ways to reflect the Sun’s heat. Such radical paths must be examined, but risky experiments avoided.
Many researchers are exploring high-tech ways to help reefs survive the climate crisis. But low-tech solutions like manually pulling out seaweed have a place too.
Scientists are predicting a record sargassum bloom in 2023. It’s already starting to wash up on beaches in Florida and the Caribbean and cause a stink.
Our recent report identified how to make aquaculture – including shrimp and seaweed farming – more sustainable for Indonesians and for the environment.
Seaweed is in the spotlight for so many reasons. It all sounds too good to be true. So can this wonder weed live up to expectations and fulfill its promise to save us from ourselves?
The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
The abundance, versatility and quality of seaweed from the St. Lawrence makes this resource a real asset for Québec. We must now integrate it into our kitchens.
