The consequences of the human factor in nature are becoming increasingly evident throughout the world. Climate change is a reality , and therefore the worst of the wars that humanity faces.
Concern about this serious problem made it necessary to sign the Paris Agreement in 2015 by 195 countries. Among the different objectives, governments agreed to keep the increase in global average temperature well below 2 ° C with respect to pre-industrial levels and to redouble efforts to limit it to 1.5 ° C. In addition, before and during the Paris conference, countries presented general national action plans against climate change to reduce their emissions.
Despite these measures, the figures indicate that the most developed countries are responsible for approximately 80% of pollution , although, together, they represent only 20% of the total population. The emission of CO2 in China , for example, accounts for almost 30% of the total percentage of pollution .
However, the emission of harmful gases is not the only practice that can end our planet, because in recent years, massive logging and urbanization is increasing alarmingly.
The International Union for Conservation of Nature (IUCN) carried out a “Red List” to obtain a more complete view of the state of the environment and its biodiversity . Through 20 case studies, an international team of biologists and conservationists designed criteria that could assess the health of all of Earth’s varied ecosystems. The results thus show the ecosystems in greatest danger of extinction.
Last 2017, IUCN published a new report at the United Nations climate change conference in Bonn, Germany, in which it reported that the number of natural World Heritage sites threatened by climate change has increased by 35 to 62 in just three years , making climate change the fastest growing threat they face.
Here are some of the most threatened ecosystems according to the IUCN.
