Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
In 2011, prehistoric pits—filled with red pigment that dated to between 1200 and 1650 CE, after the deforestation—were discovered by archaeologists. The pits contained red ochre consisting of the iron oxides hematite and maghemite and were covered with a lid. [71] [72]

Species of fish were collected in Easter Island for one month in different habitats including shallow lava pools and deep waters. Within these habitats, two holotypes and paratypes, Antennarius randalli and Antennarius moai, were discovered. These are considered frog-fish because of their characteristics: "12 dorsal rays, last two or three ...

The vast majority of this deforestation is because of the production of four commodities: wood, beef, soy, and palm oil. [15]
