I am of the opinion that humanity has just about poisoned the planet. Spays and dust can travel through the air for some distance, several miles in some cases. Groundwater contamination levels have been climbing for decades. There is the issue of contaminants in livestock manure used to make that last load of
compost you had delivered. The seed developed over decades and centuries js being modified and claimed as corporate property. The ozone is still under attack from CFCs in refrigerators that were junked 20 years ago. Even if your location is secluded there is still the problem of the county or
local utility coming through with a percloram truck to keep the weeds down along the roadside and power lines leading to your home.
Not all hope is lost just yet.
Every time someone takes a few acres out of the chemical loop, nature has a chance to repair the damage we have done. Spays and dust can travel through the air for some distance, but are not applied so much on windy days in order to get the junk where it is wanted. As distance is increased from the source, the concentration diminishes rapidly. Furthermore, rains will knock some of what is in the air out of the air. Every day more people are turning to sustainable agriculture, demanding clean food, and turning to the earth for natural solutions. We have a long way to go, but we have the advantage of nature working with us. Even 7 billion humans can't beat Mother Nature.
Look for natural buffers between your place and the sources of contaminants.
Trees do a fine job of slowing wind and collecting nearby airborne sprays. Across the street from me is 70 acres of planted pines. It is not usually cost effective to spray or treat planted pines. Natural growth forest is even better. If you have a quarter mile between you and the bad guys, figure that as being pretty good. Running
water, as little as a babbling brook, can easily serve as a barrier between your
land and the evil ooze leashing out of the land next door. Next is the layout of the neighborhood. Scattered homes in the country composed of folks working 9-5 in the
city won't see a great deal of chem use, whereas hanging your shingle in the middle of Iowa soybean country is asking for abuse.
Looking at the larger map, there are big areas that offer protection. To my east is the Osceola National Forest. Its gotta be 50 miles of nothing but woods. To my north is the Okeefenokee Swamp-a giant swath of nothing but alligators, mosquitos and the occasional bootleg moonshine operation. There are State and National Parks, nature preserves, mountainous regions, and
cattle ranches that have vast stretches of land that are not suitable for mechanized agriculture. Look to the oceans and big lakes-not much going on there and lots of dilution if there is.
