UN Environment Programme: 200 Species Extinct Every Day, Unlike Anything Since Dinosaurs Disappeared 65 Million Years Ago UN Environment Programme: 200 Species Extinct Every Day, Unlike Anything Since Dinosaurs Disappeared 65 Million Years Ago. According to the UN Environment Programme, the Earth is in the midst of a mass extinction of life. Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the natural or background rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.

- NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor. NGK Laser Iridium plugs have iridium center and a platinum ground electrodes. If installed in a regular engine, they would likely last longer than most people keep their car (barring any motor problems that can cause premature plug death). All Laser Iridium plugs are an OEM design, made for a specific engine. Some feature a special resistor or electrode design, depending on the OE requirements. In their OE application, NGK's Laser Iridium plugs typically last 80-100k miles.
