If you take a look around at what’s really happening in our world, there’s an inescapable pattern of ‘what’s going on is simply unsustainable’ and in other words, it can’t go on for much longer.
Sustainability is to “meet the needs of the present without compromising the ability of future generations to meet their own needs”.
As cities began to grow with the population increase, the need for a sustainable development became more apparent as resources began to diminish in quantity and value.
Left to it’s own devices, the Earth is a sustainable system. However, over the past two centuries, the accumulated impacts of one specific group of actors in that system, the humans, are now threatening the stability of the whole thing.

Instead of burning fossil fuels that will be depleted within short generation, alternative energies such as the wind turbine or solar panels needs to be implemented to sustain and care for the resources that remain. The concept of reducing our Carbon footprint in the world is the more modern way of looking at sustainable living, in which the World realises humans have not used resources wisely.
By looking at the changes over the past centuries, an International network of scientists have unanimously concluded that human society is altering natural functions in three fundamental ways. And consequently, they were able to define four basic conditions that must be met if we want to maintain the environmental services that sustain human society.
To become a sustainable society, we must eliminate our contributions to:
No1. The increase of concentrations of substances extracted from the Earth’s crust (heavy metals and fossil fuels)
No2. The increase of concentrations of substances produced by society (plastics, dioxins and DDT)
No3. The physical degradation of nature and natural processes (harvesting forests and destroying habitat)
And finally, conditions that undermine peoples capacity to meet human needs (unsafe working condition and low
