Interstitial lung disease Interstitial lung disease Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of lung diseases affecting the interstitium (the tissue and space around the air sacs of the lungs). It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, perivascular and perilymphatic tissues. It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage. But in interstitial lung disease, the repair process goes awry and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it more difficult
Person-affecting view existing in the future than has ever existed). Person-affecting views are also important in considering human population control. A weaker form of person-affecting views states that an act can only be bad if it is bad for some existing or future person. Person-affecting views can be seen as a revision of total utilitarianism in which the "scope of the aggregation" is changed from all individuals who would exist to a subset of those individuals (namely those individuals who already exist). Some philosophers who have discussed person-affecting views include Derek Parfit, John Broome, Larry Temkin, Tatjana Višak, Gustaf Arrhenius, Nick Beckstead,
