This is where individuals that are more suited to take advantage of the resources in the environment – be they food, shelter or mates – are more likely to survive. For instance, carcasses of whales may support fauna such as crabs, lobsters, sharks and fish, for up to 80 years.ĭeath is also needed in order for species to evolve and become adapted to their environment: evolution via natural selection, otherwise known as “survival of the fittest”. In fact, many animals have evolved to feed off other dead animals – these are the scavengers, the ones that clean up the mess – and carcasses can attract thousands of animals. Without dead animals many species would starve to death.
There are many arguments against what the BBC crew did: first, death is a natural process in the animal kingdom. So, was saving the penguin the right thing to do? A controversial move
Indeed, the goal for any nature documentary crew is to capture the living world without succumbing to emotional distress, and thus the urge to alter the things they film. You’ve invested in it, become interested in it, attached to it – would you be able to let it die, or would you want to save it? Well, while filming an episode of Dynasties, a BBC crew decided to intervene, causing controversy in the process.Īs noted by presenter David Attenborough at the end of the episode, intervention by film crews is “rare”. You’ve been filming the natural world for weeks, following this individual. Picture this, a cute baby penguin, blown down a gully during a fierce storm, with no escape.
