Explanation:
In 2003, the U.S. Environmental Protection Agency (EPA) proposed that in determining any risk, regulators should assume children have 10 times the exposure risk of adults to cancer-causing chemicals. Some health scientists contends that these guidelines are too weak. They suggest that, to be on safe side, we should assume that the risk of harm from toxins is 100 times that of adults. Others support doing this on ethical grounds, they say it is wrong not to give children much greater protection from harmful chemicals in the environment.

Attachment; Harry Harlow; warmth and comfort.
Explanation:
Attachment is the positive emotional bond that develops between a child and a particular individual. Harry Harlow conducted a classic study with infant monkeys. They were given the choice of cuddling with a surrogate wire monkey equipped with milk or a surrogate wire monkey covered in soft terry-cloth that did not provide milk. The infant monkeys preferred the warmth and comfort provided by the terry-cloth monkey.
In 1959, Harry Harlow conducted a classic experiment to study the behaviour of infant monkeys that were separated from their mothers at birth, so as to test the effects of the separation on the infant monkeys.
