Earth Day is celebrated every April 22 worldwide after it being declared in 1970 by the United Nations recognizing that the planet and its ecosystems are home to humanity and thousands of species of fauna and flora.

A day that seeks to draw the attention of governments and citizens of the world on the importance of achieving a balance between the economic, social and environmental needs of present and future generations. However, while efforts are being made by certain social and political sectors, human activities continue to be the cause of the current risk situation that our planet is in. The following are 7 relevant facts collected by Contagio Radio and that highlight the current state of environmental deterioration.

1. Loss of wildlife

Evidence collected in a report conducted in Madrid between 1970 and 2012 named "The warmest years in history: Why is our planet heating up? " shows that there was a 58% decrease in vertebrate, fish, bird, mammal, reptile and amphibian populations worldwide. If we continue with the current trend "it is estimated that in four years, we will live the disappearance of two-thirds of the world's wildlife".

On its part, Latin America has lost 83% of the fish, birds, mammals, amphibians and reptiles populations in the last 40 years; something that must not only cause concern among environmentalists but everyone since these species guarantee the tissue of the ecosystems that sustain human life on Earth.

2. Pollinators are facing extinction

Bees are currently a species that is in danger of extinction, and without these pollinators life in planet could also be extinguished. Several studies have shown that monocultures and pesticides are the main cause of this situation; it must be noted that 71 out of 100 vegetable plants that provide 90% of the food in 146 countries are pollinated by bees, as highlighted by the Food and Agriculture Organization (FAO) of the United Nations.

3. Half of all coral reefs have disappeared

The World Wildlife Fund warns that the planet has lost almost half of its coral reefs in the last 30 years. The situation has been allowed to advance to such an extent that even if global warming could be stopped, scientists believe that more than 90% of corals will die before 2050.

4. The planet has lost 64% of its wetlands

The Ramsar Convention has called to action 168 countries due to the fact that in the last 100 years 64% of the planet´s wetlands have been lost, and the species population of these ecosystems has been reduced by 66%.

In addition its degradation continues to advance at a rate of 1.5% per year, destroying thousands of species that are nourished by these ecosystems.

5. Climate change has affected Earth’s natural activities by 80%

A joint research by the University of Florida, the ARC Centre for Excellence in Coral Reef Studies and the University of Queensland, concludes that global warming has caused changes in 80% of the studied cases.

This analysis was made by scientists from 10 countries who indicated that water fleas, salamanders, panthers, penguins and Canadian birds, as well as other species of fauna and flora changed their size, color or population due to the high temperatures that earth currently suffers.

6. High Agro-industrial impacts

After several decades of unrestrained industrialization of agriculture, the evidence about the environmental impacts that it generates is overwhelming as pointed out by the FAO. Industrial agriculture is responsible for 70% of deforestation in Latin America.

Regarding this situation, Friends of Earth International (FoEI) published a report showing that after four decades of scientific evidence, agro-ecological agriculture is the most effective response to the environmental challenges that threaten food supply, which are climate change, soil erosion, water scarcity and loss of biodiversity.

7. North Pole’s meltdown has reached record-breaking figures

The Arctic has set again a new record. The largest ice loss in history was recorded this year. At its peak the total marine glacier only occupied an area of ​​14 million square kilometers; this means that it has lost an ice equivalent almost equal to the size of Bolivia, establishing a new maximum record for the third consecutive year as informed by the U.S. National Snow and Ice Data Center.
