Explanation:Sustainable development is development that meets the needs of the present without COMPROMISING the ability of future generations to meet their own needs. It contains within it two key concepts:the concept of needs, in particular, the essential needs of the world's poor, to which overriding priority should be given; andthe idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs."Sustainable Development aims to address all the environmental, economic, and socio-political problems, without compromising either one another and without jeopardising human capability and development.Can sustainable development be achieved?Maybe, but it is very difficult. Due to a number of factors, including LACK of regulation, lack of widespread political support(eg. developing countries want to grow economically) and economic support (eg. big multi-national corporations don't want environmental regulations--calls it unnecessary bureaucracy).But all is not doom and gloom. The United Nations Development Programme (UNDP) developed the millennium development GOALS in the Millennium Summit in 2000 which comprised of 8 goals that were to be achieved by 2015.These were:To eradicate extreme poverty and hungerTo achieve universal primary educationTo promote gender equalityTo reduce child mortalityTo improve maternal healthTo combat HIV/AIDS, malaria, and other diseasesTo ensure environmental sustainabilityTo develop a global partnership for developmentMore Info here: Millennium Development GoalsWhile many of the goals were addressed, there was some shortfall and a new Sustainable Development Goals (SDG) was established in 2015 for the next 15 years that due to the expiry of the Millennium Development Goals in 2015. The SDG was officially adopted on the UN Sustainable Development Summit in New York on Sept 25-27, 2015. The new SDG targets will be reviewed in 2030 when that will expire.The SD Goals are the following:End poverty in all its forms everywhereEnd hunger, achieve food security and improved nutrition and promote sustainable agricultureEnsure healthy lives and promote well-being for all at all agesEnsure inclusive and equitable quality education and promote lifelong learning opportunities for allAchieve gender equality and empower all women and girlsEnsure availability and sustainable management of water and sanitation for allEnsure access to affordable, reliable, sustainable and modern energy for allPromote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for allBuild resilient infrastructure, promote inclusive and sustainable industrialization and foster innovationReduce inequality within and among countriesMake cities and human settlements inclusive, safe, resilient and sustainableEnsure sustainable consumption and production patternsTake urgent action to combat climate change and its impactsConserve and sustainably use the oceans, seas and marine RESOURCES for sustainable developmentProtect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity lossPromote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levelsStrengthen the means of implementation and revitalize the global partnership for sustainable developmentMore Info here: Sustainable Development Goals .:. Sustainable Development Knowledge PlatformSo as you can see, targets are being achieved but at a very slow level. It is mainly the UN who has initiated sustainable development goals. But without the cooperative support of those with power like governments of both developed and developing countries, businesses that generate a lot of money and services and the CIVIL society and NGOs. It will be difficult to achieve complete sustainable development often due to overlapping national, political and economic interests.But luckily now major economies like the US, China, India, Brazil, European Union, etc. are working towards addressing one of the major impediments to sustainable development which is CLIMATE CHANGE due to the severe risk it produces to food security, marine and land biodiversity, as well as the economy. I suppose there needs to be a similar approach to sustainable development goals from countries to achieve the goals. Just like how CLIMATE CHANGE is viewed by many governments as a serious problem that needs an urgent solution. Sustainable Development Goals also need the same urgency to have them addressed.hope that you all are satisfied with this answer .it will help you in your holiday honework...
