Green reads – ozone layer, exhibition train, toilets and lots of wind


Hi there. I haven’t been able to keep up with the blog lately. Life’s been busy. So I thought I’d write some short stories. I’m thinking that this way I’ll be able to blog and find a way to keep the communication going. I’m already feeling good about this. As always, shoot your questions and thoughts in the comments section below. Here goes.

Is our earth loosing its sunscreen?

Our planet has a sun shield, its very own sunscreen – the ozone layer, that protects the living systems from harmful UV radiation. In the 1970s, researchers began examining the effects of chlorine on this layer. In the following years, ozone-depleting substances were identified and banned, but not all. The general perception that the ozone layer is now safe has been impeached by a recent NASA study. It says that a certain ozone-depleting compound is lurking in huge quantities in our atmosphere. This compound is carbon tetrachloride (CCL4). Find out more here:

All aboard the Biodiversity Express

Science Express is a science exhibition on rails. Two years back, it was renamed to ‘Science Express Biodiversity Special’ or SEBS to better fit its new theme – biodiversity. Half of the coaches of this AC train are dedicated to this theme, while the other half deals with Climate Change, Biodiversity and Water, Sustainable Environment and Energy Conservation. The schedule is up and the train will be at Thrissur from 24th November through 26th and will head towards Kollam after. It is moving north I guess and has still a lot of stations to cover, so if you are near any of those, get on it! See the schedule and tour route here. More information on SEBS here where you can find some contact information. Exhibition is open to all and is FREE.

India really really needs toilets

Source: The Economist

This map has India painted in bloody red color because half of its people practice open defecation. It doesn’t just spread smell, it spreads diseases and stunted growth. Right now, I want to know how many toilets have been really built. So I look up India’s very own data platform and I want to say that it is such a relief to not see a region where there was ‘no data available’. When I go there, I see a map, with so much pink (not so good a distribution of toilets). The map boils down to this:

Increasing trend has been seen in India in households having toilet facilities (36.41% in 2001 and 46.9% in 2011). Kerala, Mizoram and Lakshadweep State/UT have the higher households having toilet facilities in both 2001 and 2011 in comparison to other states. Lakshadweep has the highest households having toilet facilities 89.2% in 2001 and 97.8% in 2011. Seven States viz. Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Odisha, Rajasthan and Uttar Pradesh are below the National estimate 46.9% in 2011. – Source:

Can the windiest place on the planet be the best place for wind farms?

Apparently not. Mt Washington in the US is the place that is the windiest but it is not practical to have a wind farm there because well it is simply too windy. It causes severe icing, not easily accessible and is very damaging to be concise.

That’s it for today. Hope you found something new and interesting to read!

  1. I feel like a social entrepreneur could address the lack of toilets, because as you mention, it is a huge issue. or there could be a charity dedicated to building portapotties.

      1. It’s so crazy how we Americans take this amenity for granted. I’m really happy that the prime minister is taking action, and that disease will atrophy.
