What is an eco-friendly vehicle?
Tadasmi Koul, Noida, U.P
An Eco-friendly vehicle is one which leaves behind no harmful residues in the form of gases from fuels like petrol or diesel, or toxins from battery packs/fuel cells. Unfortunately, such a vehicle does not exist.
The main criteria today is emission which is determined by the fuel, the engine (the direct injection engine is superior to the conventional carburettor engine) and the use of catalytic converters. The fuel quality is most important. Direct injection engines and catalytic converters function best to minimise emissions only with high quality fuel. Toyota, for now, may have the best solution.
It has designed a hybrid car called Prius. The car runs on a combination of electric power and a petrol engine to deleiver an effieciency of 28 km/litre.
MY sister has kept 400-500 earthworms. She says earthworms eat up debris, where they have been kept and their castings can be used as fertilisers. Do earthworms really eat debris and convert it to something useful? Aren’t they just borers ?

Your sister has done a wonderful thing by keeping these wonderful wriggly earthworms. Earthworms are borers. But this aerates the soil helping it to absorb water and air. Earthworms recycle waste equivalent to their body weight each day. They eat up all the organic matter — but are strict vegetarians — and convert it into top grade fertiliser with the qualities of humus and correct NPK (nitrogen, phosphorus and potassium) balance which are essential for a fertile soil.
What your sister is doing is called vermicomposting. Vermicomposting involves keeping earthworms in a pit containing organic waste like kitchen and garden waste. Earthworms eat up all this organic waste and the excreta they produce is used as an organic fertiliser.
There are hundreds of thousands of cows and buffaloes roaming the Indian roads causing nuisance to the traffic. How can this stray cattle be utilised?

Catile on the streets have been let astray by their owners after they have stopped producing milk and hence nobody is willing to take care of them. Some voluntary agencies like the Sanjay Gandhi shelter for animals in Delhi tends these cattle. Some of the cattle, however, do produce milk. Due to shortage of grazing grounds in cities, cattleowners leave them to graze during the day and milk them in the evening when they return home.

I am student of class 8th. I was very happy to read something on environment specially meant for children. The article on Patent Rights and ‘Wealth from Waste’ were very interesting. It would be helpful if you could involve children from Nepal and include information on environment of the other countries too.
I am a student of VIIth standard. I am very happy that at last a practical, useful and educational ecological magazine for children has been launched. I’ve enjoyed reading useful facts about gobar and the other articles.
It is not easy to read Gobar Times as reading ugly facts about our environment is not easy. I feel guilty for everything

Like a newly born baby is lovelier than either of the parents, your first issue of Gobar Times was indeed attractive and full of information. I am going to share all its information with children of our central school.
We at Narora, unlike many Delhiites, are not unfamiliar with cow-dung cakes. I will share the information with the humble villagers who are sparing the nation of nearly 2000 MW electricity, heat and tons of chemical fertilisers by using cow dung.
There is need to involve children at an early age. Your cartoon on polythene bags was very appealing. We look forward to future issues and sharing our experiences with you.
Gobar Times is fun and has lots of information in it. Its pictures make it attractive. The main aim of the magazine is to- how to use waste in a clever way. We should not throw the garbage into the river, but where should we throw it?

Please try to make it more interesting and the language little easy so that our small brothers/sisters can also enjoy reading it.
Kannupriya Sarna, New Delhi Gobar Times is good and I like reading it but can you be so kind to just change you title? Please. It bugs me. But I liked your
