The Day after Diwali

It’s the day after Diwali. Last night a huge number of people all across the city celebrated the festival by lighting up firecrackers. This morning the sweepers have swept away the remains of those crackers, and well, we think that’s the end of the story. But no, unfortunately our episode with the fireworks doesn’t end that easily. Firecrackers leave behind an after-cloud of toxic substances that are harmful in various ways.

So today let’s take a look at the harmful substances that linger on in the atmosphere, long after the colourful fireworks display has died down.

Fireworks consist of gunpowder and some ‘unique’ chemical substances that give them their colour and effect. Some of these substances include cadmium, barium, dioxins, strontium and perchlorates, apart from other chemicals. If you think that use of fireworks doesn’t really cause much harm, let me tell you what these ‘unique’ chemicals alone are capable of doing.

Cadmium: It is widely used in fireworks without any restriction. But this is one of the 6 substances that are banned by the European Union’s Restriction on Hazardous Substances (RoHS) because of its life-threatening nature. Cadmium is a well-known environmental hazard and also carcinogen (cancer causing agent). I do not know why the Indian government has not imposed a similar ban on the use of this substance as of yet?

Barium: It is used in fireworks to bring in a greenish colour when it is combusted. Once combusted, the fumes that come out of barium-induced fireworks are known to accumulate in your lungs and cause Baritosis (symptoms like cough, wheezing, and nasal irritation among others). Barium also affects our nervous system and may cause cardiac problems, weakness and paralysis!

Dioxins: They are highly toxic substances and they are well-known environmental pollutants. Besides, they are also known to cause damage to the growth and immune system of young children. And yes, they are carcinogens too.

Strontium: It is a radioactive substance and it’s known to cause skeletal diseases that include bone cancer. It is a big threat to children as it interferes with their bone growth.

Perchlorates: They are the substances that help in the combustion of fireworks. They are known to damage the thyroid gland, causing diseases like hypothyroidism and thyroid cancer. They hinder growth of the body and so they affect infants, children and pregnant women the most.

These are just some of the problems that fireworks cause. Obviously then, fireworks don’t make our celebration a happy one!

From Ideas to Action—Sacred Heart High School, Vashi

Image
25th January 2011 ‘This is my plant!’ piped a tiny student of Sacred Heart High School, proudly showing off her sapling. We were impressed—these students, and their eco-club in particular, have taken decisive steps to make their school a greener and healthier place.       Our visit began with the eco-club, led by their teacher Mrs. Nirmala, showing us their garbage management system, where wet waste is composted and used as fertilizer for plants. This led us to their next initiative, a small garden of medicinal plants. They then explained how they’ve succeeded in combining environmental consciousness with utility by setting up an organic garden where they grow vegetables with the manure generated from the school’s wet waste. They also went on to show us how they are trying to involve other students in their greening activities by getting them to bring their own plants to the nursery.

St. Paul's Convent, Dadar Girls Get Set to Audit School Waste

Image
September 13, 2011 Team GreenLine saw itself at St. Paul's Girls' Convent High School, Dadar on a warm Tuesday morning, and it was there to conduct the school's first session, in this, the Second Edition of the Green Schools Campaign.There were a good number of things we noticed as we entered the school premises itself. For one, even though there is not too much space that the school can consider its campus, there is a whole lot of environment-friendly work being done here. We noticed a number of trees all around, and also the presence of dustbins all over the place. What however, really caught attention was the fact that even though the school was going through a recess, and even though there were students eating all over the place, there was not a single chip packet, chocolate wrapper, or food waste anywhere to be seen. This shows that the girls know the value of keeping the school as tidy as possible and also that unnecessary wastage itself is wrong.  Our session s

Setting the Standard—Sacred Heart High School, Vashi

Image
3rd October 2011 The students of Sacred Heart High School Vashi are not only implementing green projects in their campus, but are also making sure that environmental consciousness becomes a permanent part of their school culture. In their second session on Environmental Leadership, the students of the Eco-Club presented the draft environmental policy that they have been working on. The most striking feature of the policy so far is that the draft was prepared in an entirely democratic fashion. The process began with all students from Stds. III to X participating in a competition to select the best policy suggestions. After this, the teachers selected the best suggestions, which were debated by the eco-club members and the house captains. The policy was then drafted by the eco-club. The environmental policy covers four sectors—Supplies, Waste, Energy and Events—and includes a variety of possible practices, from reusing decorations at events to having regular energy consumption report
