forced migration brought on by global warming

[keannu]

Does it make sense that the answer for this question is b??? I can never understand why. Whales' migration was caused by global warming, and how can it prove they whales are healthy? Does it make sense? Can someone explain why it is?

ex)Part of our responsibility as marine biologists is to help protect aquatic animals and their habitats. To do this, we mst better understand our ecological footprint, or how human demands upset the ecosystem. Thank about the numerous whales being stranded along our coastlines. In the past, this only happened if they were sick or old, but it is happening more and more simply because of forced migration brought on by global warming. Without a doubt, our ecological footprint has begun to leave its harmful mark on the planet.

Q:What does the speaker imply about whales? Answer- b
a.Some species are on the brink of extinction.
b.Many that have been recently beached are healthy.
c.Their migration disturbs the ecological balance.
d.They should be returned to their natural habitat.

The text says that before the forced migration started only sick or old whales became stranded, implying that now it is happening to healthy whales.
