IntroductionThe concept of living within the ecological boundaries of the Earth means that we must use natural resources sustainably, this means that these resources should not be used to the point where their threshold is exceeded and run out. Although this is the case, we must also consider the issue from a social point of view. We cannot live within our ecological boundaries if the world's population lives under social foundations. In other words, we must use the world's resources in a way that sustains them, while still providing the world's population with basic living needs: this is essentially sustainable development (Raworth, 2012). Sustainable development is an attempt to combine environmental issues with socio-economic ones (Hopwood et al., 2005), this therefore includes the ideas of ecological boundaries and solid social foundations. Sustainable Development Sustainability was initially examined due to concerns about environmental degradation due to poor resource management. With a growing interest in the world and its environment; sustainability has become an important goal to achieve (McKenzie, 2004). Initially, sustainability was considered only from an ecological point of view, but this is no longer the case (Dempsey, 2011). Sustainability concerns the movement of social institutions toward greater equity in the way they meet needs within and between generations (Hirsch Hadorn, 2006). The concept of sustainable development was built around the idea of ​​three “pillars”, namely the ecological element, economic and social pillars (Lehtonen, 2004). The IUCN's 1980 Global Conservation Strategy stated that “for development to be sustainable it must take into account the future social… mid-document… benefits of the operation (Klauer, 1999). Many people have different ideas about sustainability policies due to conflicting ideas about what justice is, this could be due to different economic statuses, cultural differences etc. This therefore means that there must be a lot of reflection and that common ground must be found when building sustainable policies (Hirsch Hadorn, 2006).ConclusionWe can conclude that the statement “as we seek to live within the ecological boundaries of our planet, it is essential ensuring that there are solid social foundations for our action” is a very true statement. We cannot live within ecological boundaries if the world's population does not meet basic human needs. This is essentially living sustainably and to do this we must give value and limits to the nine ecological boundaries and the eleven social foundations.
