A possible area of change may be in your own backyard, literally. It's not a surprising fact that the lawns of most homeowners are made of natural grass, but the case can be made to replace that living lawn with a artificial grass alternative.
Now replacing your lawn with a synthetic grass equal addresses each of these environmental issues. Trickling chemicals into the ground will have a cumulative effect on the ecosystem with the chemicals leeching away into our water systems. At a time when water is tightly controlled in many places, using it to water our grass is essentially a luxury we can't afford.
Another factor to take into consideration is the elderly. As you get older your ability to maintain the lawn will dissipate as will your access to money to pay for the upkeep. The answer could very well be to replace the grass with synthetic turf.
