understand one part without having studied the whole, and therefore in arranging the material I have decided to set out the basic principles first, leaving the more sophisticated developments until later. Accordingly the next three chapters on duty, standard of care, causation and remoteness of damage aim to explain the basic negligence action, principally in relation to an action for personal injuries or property damage where the concepts are easiest to understand.

Due to the gases that are being released in the air from vehicles, it starts to destroy the atmosphere.
