Yeats, in this poem, uses an animal (swans) to represent the way time passes and changes, and the natural beauty of that cycle. He sees the swans year after year but knows that one day, even the swans will disappear from the lake.</span>
Editorial pages of a newspaper reflects the opinion of the periodical.
According to the internet, the Friar is referring to Juliet's parent that them crying is normal and natural, but since Juliet is in a better place, they should rejoice for the dead and that her soul is still pure when she goes up to heaven because she is young.
Or,
Natures tear meaning natural tears, merriment meaning happy. It is natural to cry over the death of a child but they should be happy she is going to be in a better place.
No personally animals should not be held in captivity, although yes some animals are safer while being held in captivity some zoos, particularly roadside attractions are extremely mismanaged and horrible for animal care. Animals suffer from neglect, small cages, etc. Animals love being in their natural habitat but many animals kept in zoos are forced to become domestic pets. Along with that up to 5000 animals are killed a year in zoos(Only in Europe).
