Answer:
Our generation has a unique opportunity. If we set our minds to it, we could be the first in human history to leave our children nothing: no greenhouse-gas emissions, no poverty, and no biodiversity loss.
That is the course that world leaders set when they met at the United Nations in New York on September 25 to adopt the Sustainable Development Goals (SDGs). The 17 goals range from ending poverty and improving health to protecting the planet’s biosphere and providing energy for all. They emerged from the largest summit in the UN’s history, the “Rio+20” conference in 2012, followed by the largest consultation the UN has ever undertaken.
Unlike their predecessor, the Millennium Development Goals, which focused almost exclusively on developing countries, the new global goals are universal and apply to all countries equally. Their adoption indicates widespread acceptance of the fact that all countries share responsibility for the long-term stability of Earth’s natural cycles, on which the planet’s ability to support us depends.
Indeed, the SDGs are the first development framework that recognizes a fundamental shift in our relationship with the planet. For the first time in Earth’s 4.5-billion-year history, the main factors determining the stability of its systems are no longer the planet’s distance from the sun or the strength or frequency of its volcanic eruptions; they are economics, politics, and technology.
For most of the past 12,000 years, Earth’s climate was relatively stable and the biosphere was resilient and healthy. Geologists call this period the Holocene. More recently, we have moved into what many are calling the Anthropocene, a far less predictable era of human-induced environmental change.
