Risky venture
Almost everything today is powered by batteries: phones, vehicles, clean energy projects. These have a long lifespan and immense storage capacity. But there is a fatal flaw in their persistent use: currently made of lithium, the batteries take hundreds of thousands of years to degrade, and the way they are disposed of currently poses an environmental risk. Researchers recently chanced upon an alternate source – one that uses a material found in crab shells – to store energy. But one wonders what this will mean for crab populations that are already threatened by overfishing.

Online games leading teenagers to anarchy
Sakib, a six-year-boy in my village, can easily say hundreds of guns’ name as he implements those in his regular contest in ‘Free Fire’, ‘PUBG’ etc. When his phone is caught up, he doesn’t excuse reviling his parent and even his grandmother too. It is a matter of sorrow that today in our society there are thousands of Sakibs whose first priority is only playing game on computer, let alone studying.
On October 16, last year a teenage boy was killed by his friend over playing PUBG game in Manikganj. Isn’t it high time for us to be more careful of our future assets, teenagers? One thing should not be forgotten that our today’s young generation is the asset of future golden Bangladesh.
