Could Seaweed Be the New Plastic?
Scientists are exploring an interesting idea: what if we could replace regular plastic with something made from seaweed?
Unlike traditional plastic — which is made from fossil fuels and can take hundreds of years to break down — seaweed-based plastic is designed to decompose naturally over time. That means it could help reduce the amount of plastic waste that ends up in oceans and landfills.
But there are still challenges. Right now, seaweed plastic is expensive to produce — somewhere between two and 10 times more costly than plastic. Scientists are also working on how to grow more seaweed efficiently and make sure large-scale farming doesn’t harm ocean ecosystems.
So while seaweed plastic isn’t widely used yet, it’s a promising idea that could help tackle one of the world’s biggest pollution problems.

Roblox has exploded into one of the most popular gaming platforms in the world, especially for kids ages 8–12. What started as a small company has grown into a massive online universe with more than 40 million user-created games and experiences — from obstacle courses and role-playing worlds to fashion shows and virtual adventures. In fact, Roblox now has more monthly users than Nintendo Switch and Sony PlayStation combined.
But with its huge popularity comes growing controversy. Critics say that because almost anyone can create a game on the platform, some content may not always be appropriate for younger users. That has raised questions from parents and safety experts about how well kids are protected online.
Roblox co-founder and CEO Dave Baszucki says the company takes safety seriously and has “no tolerance” for inappropriate content. The platform has introduced new protections, including limits on messaging for users under 13. Still, reports show that some kids can sometimes find ways around age restrictions, which keeps the debate going.
Baszucki also says millions of users are having positive, creative experiences on Roblox every day — and reminds parents that they ultimately decide whether it’s the right platform for their children.
Join “Sweet Tub Teddy” (as he was nicknamed) as he visits a recycling center where the more than 2,000 tubs he has collected will be made into furniture rather than go into a landfill. The next day, Teddy and his class are surprised with a bench of their own dedicated to Teddy and his efforts to make a difference. This video is excerpted from BBC News.
Kids today can swipe before they can tie their shoes — but some teachers say all that screen time may be changing the way young children learn, talk, and handle emotions. One preschool is pushing back by focusing on hands-on play, conversation, creativity, and movement instead of tablets and videos. Teachers say they’re seeing more kids struggle to explain what they want, calm themselves down, or interact socially after spending hours watching screens instead of experiencing the real world firsthand. Experts recommend no screens at all for children under 2, and no more than 30 minutes a day for ages 2–5.
