For the second year in a row, Australian marine scientists have carried out the sad task of surveying the Great Barrier Reef (GBR) to determine the impact of widespread bleaching caused by elevated sea water temperatures. And for the second year in a row, the findings are grim: Severe bleaching occurred on many of the individual reefs in the middle third of the 2300–kilometer-long system, according to the aerial survey results released today.
In 2016, severe bleaching hit the northern third of the reef. Now, surveys show a significant number of reefs in the central GBR have been hit 2 years in a row. Because it takes at least a decade for a full recovery by the fastest growing corals, there is "zero prospect of recovery" for reefs hit in successive years, says James Kerry, a marine biologist at James Cook University in Townsville, Australia.
[For folks in the USA, the length of the GBR is approximately the same as the distance from Chicago, Illinois to Houston, Texas. --Ed.]

As soon as you pass the goal line, you've got a touchdown; it matters not how much extra turf is laid down.
The length of the end zone matters in football. There are rules specifically addressing if a player goes beyond the 10 yard end zone (with or without the ball) or if the ball does. That being said a football field is generally measured as 100 yds even though it is 120 yds including the end zones.

Thanks for pointing that out.
