Mans history of development is just 5000 to 10000 years old. I am not expert of history or English language. However I am attempting to present some of the impressions and you can correct me if you feel there is some mistake in my language and spelling. 

Man living on earth started in small communities which were wanderers. He started living near some natural plant formations near water bodies . He ate plants, used them for medicine and oil and shelter. Gradually he learned selection of good plants and not so good plants. He learned to sow them in fields and that is how the agriculture developed.

Man is part of global earth and like other animals inhabiting the earth as part of the ecosystem. Man made mud houses, brick houses and now multistory flats . 800 flats in a complex with some one ha of lawn. Cooling by air-conditioning.Air conditioner cant provide fresh air only plants and nature can. Water from tanks, Walking by cars . No peace of mind. Always running running. Money money money. What is happening to health of man and environment. Living in sustainable way is a thing of past. Consumer society is using all the resources on the earth . Man has made tremendous advancement in one field only: that is how to kill masses in millions by atomic weapons. Atomic weapons stored on the earth are so much powerful that they can destroy the earth several times.

Is cancer a man made disease?

Recently there has been considerable increase in cancers and breast cancer has been detected in 3 persons in one locality in a radius of 500 meters. One person was in the adjacent house of one locality in a span of 10 years. Could it be a contagious disease?

Could the asbestos pipe lines supplying water in that locality be the cause of cancer? Pollution, excessive heat, light including fluorescent light, excessive light or any other climatic factors could be or could not be associated with cancer.

Someone put a comment that do traditional medicines have some medicine to control stupidity. Brain function may be governed by various signaling molecules . I am no expert of medicine but what produces stupid behavior and how it can be cured using traditional medicine could be matter of interest. Ipomea growing on the sides of railway tracks also known as railway creeper if consumed by cows , produced strange behavior. Datura metal fruits and seeds if consumed cause hallucinations. All kinds of "drugs" obtained mainly from Cannabis and Poppy produce stupid behaviour. In one poets saying "Kanak kanak te sau guna madakta adhikay , ya khaye boray jag va paye bauray". Datura and gold both produce insanity , datura by eating and gold by mere possession.

In Hindu mythology when a man dies and his funeral pyre has to be lit the fire must be provided by son only and not the daughter so that the man gets moksha or salvation . This is common belief of most people and if they don’t have son they won’t get moksha or salvation. This has no meaning now and in many cases it is the progressive girls who are performing this last rite. However till recent past this has been the cause of population growth as the couples go on producing children till they get male child. Some time it is 3rd or 4th or 5th or even 6th or 7th child.

India with its population is growing. Its economy too is growing . However increasing population is a problem and almost all the development is consumed in feeding hungry children I am quoting from Hindustan Times with full reference below: “Hunger persists despite spectacular economic expansion, and it is disproportionate to rising incomes. With per capita income crossing $1,000, India is now considered a middle-income country.” “India’s latest hunger ranking, delivered by the International Food Policy Research Institute in Washington D.C., did not make it to television news. In the newspapers, it was buried, just another bad news story in a nation that, increasingly, does not like to hear such news.”
