Sir Paul McCartney is a huge animal lover. This was recently proved when he showed his disappointment towards the National Aeronautics and Space Administration (NASA) for carrying out certain experiments on monkeys.
He requested them to find another method where the poor speech-less animals are not to be subjected to such devastating tests.
He is also having a talk with the authorities in order to halt the funds for any such act.
The legendary artist has also written a letter to the NASA mentioning his dislike also requested not to hurt the animals for finding the answers for the several universe questions.
