Orcas are predators that usually ram ice sheets to roll them over and ditch seals and penguins, to then eat them. They communicate and work together, this has been observed for a long time.
Attacks on sailing boats also have been reported already in the 1960ies, it is not clear what causes them though.
It seems to be best to stop the engine, lower sails and behave as silent as possible. But the plastic yacht's hulls are usually not strong enough to withstand a dedicated attack, this is especially true for all the glued/laminated-in outboard locks, the rudder's shaft and the propshaft's stern tube.
If the earth or its ecosystem was intelligent and able to execute counteraction against anything damaging it, it probably would do something against mankind, just like an immunosystem's reaction.
Like Mars to Earth:
"You have a disease called mankind, but tha'll soon get away"
But up to what happened until now, there is no conscient "answer" but often just a result of man's own action, like storms due to climate change, some flooding, land slides and the like.
A dedicated action by animals or a conscious earth ecosystem is - other than shown in this Pandora flick - not something to worry about i think
