On imputation principles of environment tort liability

The traditional theories cannot explain imputation principles of environment tort liability,and the without is not an imputation principle,which is,in essence,the for abnormal jeopardy.It is difficult to protect victims if we only apply for fault to environment tort.On other hand,the environment tort is so abnormally perilous that abnormal can become a reason to make infringer take on responsibility.So the for and liability for abnormal jeopardy should be applied to environment tort at same time.
