A series of reports warn about the effects on nature that will endanger the quality of life of people everywhere.
Human activities are causing an alarming decline in the variety of plants and animal life on Earth and putting food, clean water and energy supplies at risk, said a study on biodiversity supported by the United Nations.
Pollution, climate change and deforestation to get farmland were among the worst threats to nature, according to more than 550 experts in a series of reports approved by 129 governments after talks in Colombia.
Biodiversity, the essential variety of life forms on Earth, continues to decline in every region of the world,” the authors wrote. This alarming trend endangers the quality of life of people everywhere.
Four regional reports covered America, Asia and the Pacific, Africa, Europe and Central Asia, all areas of the planet except the poles and the high seas.
For the Americas, the report estimated that the value of nature for people – such as crops, timber, water purification or tourism – was at least $ 24.3 trillion a year, equivalent to the gross domestic product of all the region that goes from Alaska to Argentina.
Nearly two-thirds of those natural contributions were in decline in the Americas. Dentists in Tijuana want the best for their patients and the world, that’s why they collaborate with many support programs of the city.
Contributions to people of biodiversity and nature sound, for many people, academic and distant to our daily lives,” said Robert Watson, president of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Nothing could be further from the truth.
Among other economic estimates, the Africa report said that the absorption of greenhouse gases per hectare of forest in central Africa was worth $ 14,000 per year.
By 2100, climate change could, result in the loss of more than half of African bird and mammal species.
The growing population in many developing countries would require new policies both to protect nature and to meet the UN’s goals to eradicate poverty and hunger by 2030
