Scientists monitored a low-lying coastal ecosystem during a period when the Earth's average surface temperature was rising.
The table shows the mean sea level relative to the level in 2000 and the area of the habitat.
| Year | Mean sea level relative to 2000 in cm | Area of habitat in km² |
|---|---|---|
| 2000 | 0.0 | 48 |
| 2010 | 3.1 | 44 |
| 2020 | 6.3 | 39 |
Calculate the percentage decrease in the area of the habitat from 2000 to 2020.
Give your answer to the nearest whole number.
Explain how global warming could cause the pattern shown in the table and lead to lower biodiversity in this ecosystem.
