To take an example, let us consider Bakr Id in the country of Bangladesh, the size of a state in India. Bangladeshis slaughter 3 million goats on the day of Bakr id. Roads turn into rivers of blood and the animals are slaughtered according to certain rituals which means torture before death by slowly slitting the throat while arcane formulae are recited. This, for over 3 million goats and God knows how many other animals just in the country of Bangladesh.
Now each goat contributes 2.9 cubic meters of methane a year to the atmosphere and each cubic meter is 0.717 kg. This translates to over 155 Million kilograms of CO2 equivalent (as 1 kg of Methane is equivalent to 25 kg of CO2) just for one day of Bakr id from a rather small country.
Just imagine the amount of green house gases released all over the world only for the purpose of satisfying culinary lust.
The tanning industry is perhaps the greatest polluter of water bodies in India. yet nothing much has been done against them as that would hurt the sensibilities of a particular community.
But Deepavali, which is perhaps the single most important festival of Hindus, can be targeted in a country where the Hindus are a majority. I wonder what the powers are behind the scenes. Even Modi seems powerless to stop them.
