The image features a line graph titled "Percentage of Land Area Covered by Forest in Selected Countries (1990-2020)". The vertical axis is labeled "Percentage of Land Area (%)" with scale values ranging from 10 to 70 in increments of 10. The horizontal axis is labeled "Year" with points at 1990, 2000, 2010, and 2020. A box labeled "Legend" specifies five categories: Finland (solid line, diamond markers) showing ~72% (1990), ~73% (2000), ~73% (2010), and ~73.5% (2020); Brazil (dashed line, star markers) showing ~65.4% (1990), ~62% (2000), ~60% (2010), and ~59.5% (2020); Indonesia (dash-dotted line, square markers) showing ~59.7% (1990), ~55.2% (2000), ~52.4% (2010), and ~49.1% (2020); Canada (dotted line, upside-down triangle markers) showing ~38.8% across all four years (1990, 2000, 2010, 2020); and Nigeria (dashed line, x markers) showing ~17.2% (1990), ~13.1% (2000), ~9.1% (2010), and ~6.0% (2020).

The line graph illustrates the percentage of land covered by forest in Finland, Brazil, Canada, Indonesia and Nigeria between 1990 and 2020.
Overall, Finland consistently had the highest proportion of forested land, while Nigeria had the lowest. Finland experienced a slight increase and Canada’s figure remained virtually unchanged, whereas Brazil, Indonesia and Nigeria all recorded declines. Nigeria experienced by far the most significant reduction in forest coverage.
In 1990, approximately 72% of Finland’s land area was covered by forest, and this figure rose gradually to around 74% in 2020. By contrast, Brazil experienced a steady decline, from approximately 65% in 1990 to about 59% three decades later. Indonesia followed a similar downward trend, although its reduction was considerably greater, with forest coverage falling from around 60% to 49%.
Canada’s figure remained almost completely stable throughout the period, at approximately 39%. Nigeria, however, experienced the most dramatic change among the five countries. Its forest coverage fell steadily from around 17% in 1990 to only 6% in 2020, representing a reduction of roughly 11 percentage points.
