Setting irrigation systems to run longer results in a reduction of water use is an example of a correct pairing of a sustainable practice and its impact to the environment. The irrigation system is one of the techniques used in agriculture to maximize the use of the water and extend the span of its usage over time.
Creating more wind farms results in a reduction of fossil fuel use is the most sustainable practice as a correct pair, alongside with its impact on the environment. A fossil-fuel power station uses fossil fuels. Coal is a typical examples. Wind farms also produce energy and this is a cleaner source of energy because it does not produce any pollution.
