In countries that take environmental responsibility seriously, the government & respective agencies are generous in advocating & investing in healthy practices to reduce wastes, conserve/ farm energies, reduce carbon emission etc.
The solutions come in the form of heavy subsidies and/or reimbursements (tax rebates) for installations/ implementation of environmental friendly equipments.
The denser the population becomes, the greater the need for energy, and when supplies of fossil/ natural fuels (commodity) becomes limited, the burden of costs increases. Therefore, governments explore feasibility to implementing nuclear energy, solar/ wind/ hydro/tidal energy solutions.
On national scale, fuel efficient diesel engine vehicles come in waves, generation after generation, hybrid engine cars start flooding the markets.
Public amenity & street lighting are being replaced by the hundreds, using LED technology. In some cases, solar/wind powered LED streetlights (ideal for rural developments, requiring less attention to maintain).
Household supply of water comes in different qualities; potable water for taps in the kitchen, raw hard water for sanitary uses, recycled water for industrial purposes. The implementation costs may be steep, but the long term costs savings for processing water (requiring energy) is greatly reduced. And the recurrent costs savings on year multiplies exponentially against the number of taps.
Intelligent architecture, interior designs, appropriate application of materials, colors & texture application, makes for great environmental friendliness in reduced reliance on lighting in the day, conserved lighting in the night (dimming when not in use), less reliance on heaters and/or air-conditioners, unless absolutely necessary.
Integrated compost systems within household sinks processed food waste into pulp, and can be used either as agricultural fertilizers and/or bio-detergents; reducing the need to produce bottled detergent.
Recycling of wastes also require great deals of energy to break down the materials, in order to re-process them into feasible products again. But instead of investing too much into the grind, granulated materials can be converted into building materials, instead of having to mine for granite or sand. Perhaps not applicable for housing as yet, but can be used for footpaths & gutters in the meantime.
Processed foods are one of the world’s largest consumers of energy, materials and wastes. No doubt it may be necessary to process some food staples in order to facilitate distribution, lengthen shelf life etc. However, it is also good to be advocating eating fresh, reducing the reliance to pack & can them.
Should the above concepts be implemented, it shall also require every individual’s conscientious effort in every little way, to make saving GAIA possible.
