What is the most likely cause of the Cretaceous mass extinction?

This was most likely caused by an asteroid hitting the Earth in what is now Mexico, potentially compounded by ongoing flood volcanism in what is now India.
Why should we save dugongs? Wherever they survive, dugongs play an important role in maintaining coastal ecosystems. Their constant browsing of seagrass encourages regrowth – ensuring critical habitat and feeding sites for a host of other marine species, including turtles, dolphins and sawfish.
Why are dugongs endangered in Australia? The Dugong is threatened by coastal development and poor catchment management leading to siltation and the loss of seagrass beds. Isolated Dugong populations are vulnerable to local extinction as a result of losing seagrass beds after stochastic events such as floods or cyclones.
