Question

1) In the passage, vaccine is given to cows to reduce the production of methane. Do you think this process of testing on animals is justified? Why?
​

Answer 1

Answer:

cows grazing peacefully in the vicinity of New Zealand’s farming science research institute AgResearch look much like any other. They plod slowly around the pastures, heads bowed as they tear up mouthfuls of grass and let out soft, low moos.

But some of these animals are not like the cattle you might find on other farms. Away from view, inside the hard-working stomachs of these cows, an experiment that could potentially change the planet is taking place.

They have been given a vaccine against certain gut microbes that are responsible for producing methane as the animals digest their food. Methane is one of the most egregious of greenhouse gases, roughly 25 times more potent at trapping heat than carbon dioxide.
