分析：本句的主句为alltherubbishAmericaproducesthroughtheentire21stcenturywillstilltakeuponlyone-12,000thoftheareaoftheentireUnitedStates.";其中Americaproduces"为定语从句，作alltherubbish的定语，关系词在定语从句中作宾语，被省掉;evenifAmerica’strashoutputcontinuestoriseasithasdoneinthepast,"和eveniftheAmericanpopulationdoublesby2100"两个从句并列，皆为evenif引导的让步状语从句。
