Answer 2

Answer: 241,655‬ km²

Explanation:

If only 15% will have sufficient levels of calcium carbonate, that means that 85% will be damaged by low levels of calcium carbonate by 2050.

Currently there are 284,300 km² of coral reefs.

If 85% are damaged, that would translate to:

= 284,300 * 85%

= ‭241,655‬ km²
