<s>[INST] The next text is a question of a member of the European parliament:"Ethylene is one of the volatile organic compounds released into the atmosphere through incineration processes, by the petrochemicals industry, road transport and through the burning of timber, etc. However, it is also a natural plant hormone involved in the maturing of plants and causes, inter alia, fruit to ripen, leaves to fall, dormant periods to cease and flower parts to mature, and it is physiologically active in very low concentrations (0,01-0,1 ppm).
