Ghana to put spotlight on oceans at Maiden Blue Economy Summit

Ghana to put spotlight on oceans at Maiden Blue Economy Summit

Ghana News, International, Science & Technology
Ghana’s commitment to the protection and sustainable management of its oceans takes centre stage as the nation prepares to host the inaugural National Blue Economy Summit. The summit, scheduled for May 31st and June 1st, aims to raise awareness about the critical challenges facing our oceans while highlighting the immense opportunities for Ghana’s transformation. Dr Eugene Owusu, Ghana’s Special Advisor to the President on the Sustainable Development Goals (SDGs), spoke passionately about the urgent need for action to save the world’s oceans. Addressing attendees at the Media Launch of the National Blue Economy Summit on Wednesday, May 17, 2023, Dr Owusu referred to the current state of the oceans as a “time bomb” that requires immediate attention. The decline in ocean hea...
Do single-use plastic bans work?

Do single-use plastic bans work?

Science & Technology
The problems caused by plastic waste are rapidly increasing around the globe, but it still serves a useful purpose in food packaging. Can plastic still be a green option? In many countries, plastic straws are increasingly hard to come by. In the UK, where I live, they were banned completely at the end of 2020 along with plastic coffee stirrers. So when I am offered a straw in a restaurant or café now, it's usually made of paper. But these paper straws bend and go limp after a few minutes in my drink, and in the end they all go in the general waste, either to an incinerator to be burned to produce energy, or to landfill. Do I really want a paper straw? I am lucky enough to be able to lift that glass to my lips, so I might as well do so. And just like that, a step towards zero wast...
Can we fix our ocean noise problem?

Can we fix our ocean noise problem?

Science & Technology
Researchers are uncovering just how large the impact of man-made noise is on ocean life. But there are some surprisingly simple ways we could tackle this overlooked pollution problem. In the aftermath of the terrorist attacks on 11 September 2001, a great lull fell over North America, above and below the water. Understandably, fewer people were traveling by air. But ship traffic was also significantly reduced, even as far north as the Bay of Fundy in Canada. As a result, underwater noise in the bay dropped by an incredible six decibels to below 150 Hz – equivalent to a soft rain or cat's purr. The area is frequented by North Atlantic right whales, so scientists at Duke University decided to see if the quieter waters had any impact on the giant mammals. Sure enough, ...
