The DNA repair ability of a cell is vital to the integrity of its genome and thus to the normal functionality of that organism. Many genes that were initially shown to influence life span have turned out to be involved in DNA damage repair and protection.
Examples for negative production externalities include: 1  Air pollution from burning fossil fuels. 2  This activity causes damages to crops, (historic) buildings and public health. 3  Anthropogenic climate change as a consequence of greenhouse gas emissions from burning oil, gas, and coal.
Pollution has reached its peak giving rise to global warming. With the rise in. industrial pollution global warming has been increasing at a steady pace. Smoke and greenhouse. gases are being released by industries into the air which causes increase in global warming. Melting of glaciers, extinction of polar bears, floods, tsunamis, hurricanes are few of the effects of. global warming.
