Summer(Haiku poem)

This poem states about the harmful impacts of summer and its scorching heat upon the biosphere.
Not only do the animals suffer but also the plants and humans.
Throughout the context of the poem, the narrator is seen to sympathise with the misery, pains suffered by those Mother Nature's beings. Except for one.
Who is that and why is that so?
