If whales were to disappear from the Earth, say tomorrow, how would that loss impact the planet, and how would it be experienced and felt by Gaia and all of life?

This is difficult to describe in detail as there are things you do not know that are happening other than in a vague sense of changing energies and a worsening of the geomagnetic forces emanating from the Sun, but there is an interplay that is felt by the whales and so they are providing a powerful intention to summon divine healing and repair for many aspects of Gaia and because humans are so unaware of things, their contribution is sometimes less overall than the whales. There are not enough truly awakened humans to make huge changes for the better; their potential is greater but their disconnect from higher self and the higher realms and their lack of awareness of their place in things and their true potential makes most humans non-contributors in terms of any possible gain for the better. This is most unfortunate and would normally be a source of alarm and certainly lead to chagrin to be bested by a sea creature in terms of bringing good into the world.
