I think that the question is not the right one: one could argue that is some places it might be very difficult to reach all the SDG. However I feel that it is very positive to set such concrete goal and put in urgency to reach them, or to come as close as possible to individual goals.

Exactly, Thanks Dear Sir Eberhard Weber.

"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs," according to the Brundtland Report of 1987. To note, instead of a holistic approach to and temporal processes toward development that might lead us to the end-point of sustainability, some advocate a focus on sustainability, full stop, as the rightful end of human–ecosystem interaction (meaning, homeostasis). But, while sustainable development (never mind sustainability) may be a pipe dream—or what this query refers to as a myth—there can is no doubt that the Sustainable Development Goals are not: difficult to accomplish as they may be, the 17 Sustainable Development Goals come with targets to be measured with indicators. To the point: what else do we have at hand if the Sustainable Development Goals do not suffice? Global economic growth per person, led by emerging economies and a population that topped 7.3 billion in 2015 (and is now at 7.7 billion), is putting great stress on the earth's ecosystems. Pressures are global, regional, national, and local: they impinge simultaneously on such crucial earth systems as the carbon, nitrogen, and water cycles. It is patently obvious that mankind is pushing ecosystem functions past thresholds: the earth could suffer sudden, non-linear, and potentially devastating outcomes from climate change, environmental pollution, acidification of the oceans, loss of biodiversity, and depletion of fossil resources, including energy and groundwater. Like it or not, the shared focus on the triple bottom line of economy, environment, and society that the Sustainable Development Goals represent is a consensus on which the world (including its societies and individuals) can build: if no-growth (never mind degrowth) is not an option, there is no alternative.

Thank you, Sir Oliver Serrat for your valuable observation.

Dear Md. Saidur Rahaman, Whether the implementation of the principles and goals of sustainable development (SDG) into economic processes becomes a reality or a myth depends only on the human being in the next several decades. Best wishes,
