Q6 Pesticides should never be applied unless they are necessary to maintain plant health. Using preventive cover sprays, where pesticides are sprayed several times a year on a calendar basis, has been shown to create more pest problems than it solves. Not only do cover sprays create potential for pesticide runoff and increased human and pet exposure, they actually create pest problems by suppressing predators, parasitoids and diseases that keep plant pests under control. It is common to see outbreaks of spider mites, aphids and scale insects where pesticides are used. Only spray one plant at a time, and only if it is necessary.
Q7 Extensive agricultural and industrial water use reduces the amount of fresh water available for human consumption.
Damming and diverting water threatens biodiversity, increases evaporation water loss, lowers downstream water levels, and reduces valuable sediment deposits.
Water contaminated by industrial waste, agricultural fertilizer, mining discharge, and improper human waste disposal contributes to 80% of the world’s water-borne diseases.
Fertilizer runoff and other waste contaminants have created over 400 oxygen-deprived ‘dead zones’ in the world’s oceans, constituting 95,000 square miles of water.

Q1 The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Its job is to hold the wastewater long enough to allow solids to settle down to the bottom forming sludge, while the oil and grease floats to the top as scum.
