What is sustainable lifestyle? What are its factors? How it can be achieved? You can find all the answers here... :)

2.  Sustainable living is a lifestyle that attempts to reduce
an individual's or society's use of the Earth's natural resources and
personal resources
Practitioners of sustainable lifestyle often attempt to reduce
their carbon footprint by altering method of transportation, energy
consumption, and diet
One conception of sustainable lifestyle expresses what it means in
triple-bottom-line terms as meeting present ecological, societal, and
economical needs without compromising these factors for future
generations

3.  Most basic, sustainable living means living a lifestyle that
uses as few resources as possible and causes the least
amount of environmental damage for future generations to
deal with.
 Sustainable living must include a reliance on sustainable
energy.
 The energy sources used must be renewable rather than
limited in quantity.
A sustainable home should be constructed from materials
that have been produced in an environmentally friendly
manner

4. The three important and necessary factors
involved in maintaining the earth are social,
environmental, and economic, and the
environmental factor affects both social and
economic issues.
We cannot speak of one factor without
considering how another is affected by it.
The hardest factor to initiate is the social one
because so many refuse to budge upon their long
standing, wasteful, and inefficient ways of living

5. Instead of burning fossil fuels that will be depleted
within short generations, alternative energy such as the
wind turbine, solar panels, and other green energy
sources need to be implemented to sustain and care for
the resources that remain.
The definition of sustainable living means more today
than when it was first considered almost 200 years ago.
Back then it was to improve man’s conditions, today it is
to maintain man’s functional society and protect the
environment.

6. For sustainable engineering solutions and sustainable lifestyle
choices, we may consider the sustainability of our lifestyles
through subdivision into the following categories:
Energy including transport
Finite resource depletion and waste management
Water

7. The energy required to support our lifestyle may be
subdivided into the following categories:
Heating
Electricity for lighting and appliances
Transport
Embodied energy in products

8. The availability of water suitable for drinking is of significant
concern even in countries like the UK where flooding is not
uncommon. Increasing population, associated food
production and industrial processes are putting significant
pressure on our water resources. As for energy and waste,
the approach towards the sustainability of water may also be
expressed as a hierarchy:
Avoid the use of water
Use water more efficiently
Renewable sourcing of water

9. In the me way that we may think in terms of an energy
hierarchy and transport hierarchy, we may also consider the
waste hierarchy. This may be expressed as:
Avoid generating waste
Re-use of waste
Recycle
Waste-to-energy
Landfill
