关于水污染的源头及处理和解决方法的一份英文课堂ppt
What Can You Do? Water Pollution Fertilize garden and yard plants with manure or compost instead of commercial inorganic fertilizer. Do not apply fertilizer or pesticides near a body of water.
Do not drink bottled water unless tests show that your tap water is contaminated. Merely refill and reuse plastic bottles with tap water. Do not use water fresheners in toilets.
Do not pour pesticides, paints, solvents, oil, antifreeze, or other products containing harmful chemicals down the drain or onto the ground.
