The less herbicides and pesticides you spray, the less you will swim in! Use lawn clippings, compost, or manure to fertilize your lawn and garden. Use phosphate-free laundry and dishwasher detergent because phosphates in lakes and rivers can encourage algae growth, which can suffocate aquatic life. Try non-toxic products, such as baking soda or vinegar, instead of hazardous chemicals for cleaning.
