The correct answer is multiple sclerosis.
The MS or multiple sclerosis refers to a demyelinating disorder in which the insulating envelopes of the nervous tissues in the spinal cord and the brain get destructed.
This destruction disturbs the tendency of the components of the nervous system to interact, leading to an array of symptoms and signs, involving mental, physical, and on certain occasions psychiatric issues.
The animals who live in those habitats have adjusted to the local temperature so changing the climate drastically, may upset the living organisms there:)
