In the Sustainable Development Summit, which was held in New York on 25 September, the UN member states have approved the 2030 Agenda for Sustainable Development, which includes a set of 17 goals to end poverty, fighting inequality and injustice, and to tackle climate change. For the first time it has benefited from the active participation of the private sector.
These 17 new Sustainable Development Goals (SDGs) and their 169 targets replace the 8 Millennium Development Goals (MDGs) set by the international community in 2000 and ending this year 2015.
The prussian geographer, astronomer, naturalist and humanist Alexander von Humboldt dedicated his life to travel the world performing a comprehensive record of the Earth's biodiversity. In 1802 he arrived to the Andes, where he reflected on his Tableau Physique all plant species growing around Chimborazo volcano, noting their characteristics and the height at which they grew.
Thanks to this document, and after a recent expedition that has followed the same path as Humboldt, today we can see that human activity has altered the composition of the habitat of the Ecuadorian mountain forcing many of them to put their high birth over half kilometer above with respect to 1802, from 4,600 meters to 5,185, due to rising temperatures.
According to a study published by Nature magazine, 46% of the trees on the planet have disappeared due to direct impact of human activity.
The project, that involves conducting a census of trees on a global scale, also notes that there are currently 422 trees per person in the world ... and decreasing. In areas like Bolivia there are up to 15,000 trees per person, while in countries like Israel there are just two trees for each person.
The most alarming, however, is that the net destruction of trees is 5 billion a year: human resources use about 15 billion but only 10 billion are planted annually.
Deforestation is one of the most important causes of climate change. Are we going to continue this destructive pace until it's too late?
Roosevelt Island will have the tallest passive house in the world in 2017. A passive building is one that produces more energy than what it consumes, so it is respectful to the environment without rejecting the implementation of the latest technologies.
The project includes apartments and a campus of 900,000 square meters in 83 meters high.
The first six months of 2015 have broken the record for maximum temperature since 1880, when temperature began to be recorded.
According to the monthly analysis of US weather agency (NOAA), submitted on July 22, the temperature during the first half was 1.26 ºC higher than the average for the period 1880 to 2014, surpassing the previous record of 2012 set at just 0.06 ºC above the average of the last century.
Sustainable development, the impact of humans on nature and environmental care have a growing presence in the generalist media. In this gallery we will compile the news that for its importance, curiosity or viralization jump from their section to the front pages of newspapers.
The first piece of news takes us out to space
Sentinel 2A spacecraft, launched into space last Tuesday, June 23, has already delivered its first images of Earth. The collected data is sent in real time and used to record changes on the Earth's surface in periods of ten days, the time that Sentinel 2A takes to turn around the Earth.
Pope Francis recently published the encyclical entitled Laudato Si (Praised Be), which alerts the need for awareness on climate change, a struggle that is "a moral obligation" of the Church. This document, which is published a few months before the Climate Change Conference in Paris, was celebrated by the leaders of the UN and praised by the Dalai Lama.
A scientific study of Stanford University, Autonoma de Mexico and Florida says that we could be heading to the sixth mass extinction, with the corresponding threat to humans. According to the researchers, extinction rates are reaching levels unprecedented since the extinction of dinosaurs and that the solution implies a fast action to prevent further loss of biodiversity.
