I think deep down inside everyone wants a sustainable future. The term sustainable future can mean many different things depending on who you ask. the general definition of described the use of natural resources when this use is kept at a steady level that is not likely to damage the environment. It is important to find a balance that both supports the needs of your family without damaging the area in which you get the resources from. You don't want to kill off everything on your farm and have to move in a few years. That isn't very sustainable.
Food and water are your number priorities. There are several ways to grow crops without damaging the environment or polluting the water. You can create your own compost, this avoids the use of harmful chemicals. Hydroponics is an option, yes this does use chemicals, but they have a very minimal impact compared to traditional fertilizers. The option I am using is aquaculture, this combines fish and plants and has zero chemicals introduced. The plants are provided nutrients from the fish waste. It may sound dirty but I promise you would not know the difference if you bit into a better grown in a field or through aquaculture. The other benefit of aquaculture is the protein you produce from the fish as they mature.
Power is another priority that can be produced without a major impact on the environment. Many homesteads are completely off the grid and produce their own power through solar panels or wind turbines. Advances in technology has greatly improved the production and lifespan of solar panels. Many panels are guaranteed to produce power for over 25 years. Wind turbines are very efficient and can produce power with as little as 5 mph winds. The hydrogen power market is growing also. You can produce power with a small stream on your property. All three of these methods are cost effective and will help keep you off the grid.
As I said earlier, a sustainable future has many different meanings to many people. The bottom line is to live a healthy life with minimal impact to the environment around you. As always, I would love to hear your comments and see how you may be using some of the methods mentioned.
