Why more boys are being born to girls???

Its been quite a while that am reading and hearing so much about so many things, that forced me to write something.. The first thing that came to my mind was the rapid decline in female ratio.
Globally, there are about 105 to107 boys born for every 100 girls.
China having the largest gap between the girls boys ratio. It has been noted in various countries that women are giving more births to male children naturally. Some of the reasons behind this may be older fathers, stress, environmental toxins and lower maternal weight.
Pollutants like dioxin, mimic in human hormones may also be affecting the birth rates.
Lets discuss the problem in India.
This is an alarming state for all of us.
This stats are based on the 0-6 age group...
in 1961, ratio for girls:boys was 976:1000..
in 1971, 964:1000
in 1981, 962:1000
in 1991, ratio of grls:boys was 945:1000
Which declined in 2001, to 927:1000 boys..
Its declining rapidly ... and it can be seen more in rural areas...More or less cities are also experiencing the same!and this ratio reached near 800s in 2005!!
One of the reason is illiteracy leading to female infanticide and traditional mindset of ppl for a male child!!Despite of the fact that we have developed and grown immensly we are still engaged in brutal practices like female infanticide.
In rural area its shockingly common. People after discovering the new born child is female, kill the baby by adopting various means such as strangling the baby, giving her poison, dumping her in a garbage bin, drowning her, burying her alive, starving her, stuffing her mouth with salt, or leaving her outdoors overnight so she dies of exposure.
What is even more shocking is this brutal muder is not considered as a big crime in these areas. Women being women themselves (playing the role of mothers, daughters, sisters) dont realise the importance of a girl child and participate in female infanticide equally.
Depressingly, educated, wealthy and so called mordern mindset of urban people doesnt help them in offgaurding their desire for a male child.
Though they dont kill their daughter after she is born, they do try and find out the sex of their child, and abort female fetuses, which again is a crime.If this continues to fall like this or if this state remains stationary for long period of time, the state of frustration and ill practices will keep on developing to newer heights among male masses.
Many ppl will remain unmarried...... it may add to their frustration... eve-teasing and molesting will increase to heights.... due to this imbalance there may be increase in extra marital affairs too... morals and ethics of society may get ruined...mishappenings with female child will also increase.... it will be more of a male dominated society and it will be hard for ladies to get their due share...
Though nowadays govt is taking measures for the same but it alone cant do much, we, who have been sleeping till now have to wake and have to respect the arrival of baby daughters to our homes.
