Type in the correct form of the verb. Pay attention to the structure of the first conditional. If people (plant) saxaul forests at the bottom of the Aral Sea, the ecological situation in the region will improve. If we don't take drastic measures, Lake Balkhash (turn) into ecological disaster zone similar to the Aral Sea.
Plant (используется Present Simple, т.к. во второй части Future Present + Future Present с if использовать нельзя)
Will turn (используется Future Present, т.к. в первой части было Present Simple и if)
