Should adopted children have the right to know their biological parents?

No, I don't believe so. A couple takes a child in and raises the child, with all the effort, trouble and expense, and then someone comes along and say, "Just kidding!" At a minimum, they should have to pay for the cost of someone else raising their kid. And that won't begine to compensate for the emotional trauma to kid and parents. If a child had a child and they were stolen by their grandmother based on lies no this is not fair. ---- == No. the parents may a conscience desicision to give up all rights to their child. i understand some parents have to because they can not provide any of the basic needs for a child. but after they give a child up for adoption then the child doesnt belong to them anymore. However i do believe that if the parents are capable to raise a child and under go evalutaion then they should be allowed have their child returned, if the child has not been adopted already. it is a complex issue that tears the lives of so many.
