2. What is causing the environmental problems?
•vehicles giving off harmful gases •factories emitting gases •machines and vehicles making a lot of noise •uncontrolled cutting down the trees •massive use of fertilizer and pesticide •buildings, factories and other facilities occupying farmlands •people dumping garbage everywhere
