The question was : 

If genetic engineering gives the power of speech to animals, will their relationship with human beings improve, degrade or remain the same ?
 

Thank you all for your different ideas :

The answers can be summarized as :

(1)  Many human beings love their pets because of their innocence and sweetness. Once animals start speaking, this relationship of innocence will fade away.
(malini, indu, james, prerna, vidya)

(2) Many politicians without having intelligence dominate only because they can speak. Animals may similarly dominate human beings.
(ashok)

(3) Human beings exploitation of animals will decrease once the animals get the power of speech.
(ashok, veena)

(4) The relationship may remain the same since animals won't have intelligence.
(sudhir, neelima)

(5) Relationship will improve since the animals will retain their innocence and  will be able to communicate more closely.
(girish, punitha, ramya, babu, roseline)

(6) Animals will start abusing human beings freely
(ramki)

(7) Improve because human beings prefer talking animals more than dumb animals.
(victor, george)

(8) Human beings may start proposing animals for....
(devaraj)

(9) The relationship will improve with people who are kind-hearted to animals, and it will degrade with people who are cruel to animals.
(ramesh, rajesh)

(10) Will depend on the context in which animals use their power of speech.
(rajesh)

(11) There will be lot of noise pollution.
(vidya)

(12) Human beings can now use animals more effectively by giving precise instructions.
(dileepan, chock, jeyabalan)
There may also be no effect at all since most of us pay tax indirectly each day we live.
 

Question of the next survey : 

If human beings reside in buildings which can vibrate and rotate (about a vertical axis), will the mental and physical health of the residents improve?
