Hello Panditji
I have heard that beneath the Earth’s
crust, all the inorganic minerals are separated into different layers (in viscous fluid)
after being subjected to melting due earth's inside temperature.
Is it possible to take all the
inorganic wastes to greater depths into the earth through the abandoned oil wells. Won't
the problem of handling the wastes become easier?

Dear Arunji,
You have asked a very thinking question. Well theoretically, if we can dig a hole till say
the upper mantel or lower mantel or even till the core, we can thermally fuse all the
waste. But, so far no gas or oil well in the world has reached those levels. Most of these
wells are just few kilometres deep, in contrast to hundreds of kilometres required to
reach the upper mantel.
If we inject our wastes in the current wells, it will only contaminate our groundwater,
which we shouldn’t do.
Also, one is not clear what will happen if we bore a hole and reach the upper mantel.
Will the molten material come out as it happens in a volcano?
Theoretically that will happen because the pressure beneath is many times higher than
the atmospheric pressure. So it might not be feasible to put the waste in the mantel or
the core.
In totality, putting the waste in the earth's core is not a feasible solution.
Namaste. I am a BSc second
year student. What are the safe methods of getting rid of mosquitoes from the house?

Dear Shankaranji,
When it comes to mosquitoes, prevention is better than pesticides. There are many natural
and safe mosquito repellents. One of the best is neem oil. You can rub this on the exposed
parts of your skin (wrists, neck, temples, behind ears, knees and ankles) and see that it
doesn't touch clothes. Other substances that work are Castor oil, Lemongrass oil and
Peppermint oil. But also see that you are not allergic to these oils and that they don't
get in your eyes.
You can also use cucumber cubes. Remove the skin from a cucumber. Cut into pieces and
mash in a bowl. Collect the liquid and pour in ice cube tray and freeze. When frozen, rub
the cucumber cube on your hands and face.
You can make your own mosquito repellent if you can get hold of the following:
Eucalyptus oil (20 drops), Cedarwood oil (20 drops), Tea Tree oil (10 drops), and Geranium
(10 drops).
Plus, mosquitoes are attracted by the following: dark clothes, carbon dioxide (candles,
oil lamps), floral or fruity fragrances and sweaty bodies. So take precautions
accordingly.
I want to know that if I drink
milk without heating it (kachha doodh), are there any side effects?

Dear Ashuji,
Drinking milk without boiling it is not a good idea. Milk is a highly perishable product
and is an excellent medium for transmitting a variety of diseases. It is also open to
contamination during
collection, transportation and selling.
Raw milk contains a lot of bacteria that are harmful to the human body. For example,
Salmonella bacteria and E.Coli are common among animals. Infections in dairy herds may
lead to contamination of milk.
Further, the low acidity and high nutrient content make it the perfect breeding ground
for bacteria, including those which cause food poisoning (pathogens). Boiling destroys
organisms, which cause tuberculosis, typhoid, cholera, dysentery, and other non-spore
organisms.
Boiling also makes milk more digestible and fat emulsion is destroyed.
Some people say they grew up drinking raw milk and never became sick from it. However,
public health authorities know of many cases where people got sick from drinking raw milk. |
