It’s time to talk about technologies seen as clean that may be causing our planet significant harm

The CoP-26 conference that concluded last fortnight was one of the last desperate attempts by humankind to save our home. Our planet faces an existential threat, with climate change and global warming threatening to make it unliveable in a few short decades. All planets die, as they get consumed by their stars in spectacular galactic explosions that create white dwarfs and black holes, and so will the earth—in about 7.5 billion years. As a species, we have hastened this demise considerably by accelerating climate change to dangerous levels. If you read news reports and most scientific literature, a few common factors are blamed for how we have managed this feat: the use of vast amounts of concrete, vehicular exhaust, industrial pollution, air travel, and even cows belching out copious quantities of methane.
