Ecological scientist John Harte observed: “Tropical rainforests cover less than two percent of the planet and yet are the only home of at least 50 percent and possibly as many as 90 percent of all species on earth.
Keskkonnateadlane John Harte märgib: „Troopilised vihmametsad katavad meie planeedist vähem kui kaks protsenti, kuid ometi on need ainsaks elupaigaks vähemalt 50 protsendile ja võimalik et isegi kuni 90 protsendile kogu maakera liikidest.
