15,000 scientists from 184 different countries concerned about the planet, have demonstrated for the second time in 25 years, to warn humanity about the environmental trends that are destroying the Earth.
“A second notice "Is the name of the article signed by these scientists in the journal BioSience, in which they talk about the" obvious signs that we are on an unsustainable path "
But not everything is pessimism, the article also contains actions and suggestions from the scientific community to try to reverse these dire trends.
The welfare of humanity, "seriously threatened"
The big problems that humanity faces and that threaten its well-being according to experts are mainly:
- climate change,
- lack of access to fresh water,
- the extinction of species and
- the growth of the human population.
Many of these problems are still without strategic measures on the part of the rulers to be able to be reversed. And as in the case of the United States, they deny its existence.
Scientists have divided the article into 13 areas in which action should be taken urgently. Among them is:
- Create more land and marine reserves;
- strengthen the enforcement of laws against poaching and restrictions on trade in wildlife;
- expand family planning and education programs for women;
- promote a plant-based diet change (vegetarianism) and
- the “widespread” adoption of renewable energy and “green” technologies
Back in 1992 ...
This is not the first warning, as in 1992 "World Scientists Warning to Humanity”Published by the Union of Concerned Scientists. That time 1,700 scientists signed, including all the Nobel Laureates.
The new warning has been written by an international team led by Professor William Ripple from the University of Oregon. The base information with which the report was prepared comes from data from government agencies, non-profit organizations and independent researchers to warn about the “substantial and irreversible damage” that is being caused to planet Earth.
"Those who have signed this second warning are not just raising a false alarm."
Some people "might be tempted to ignore this evidence and think we are being alarmist," Ripple commented, but "scientists know how to interpret data and look at the long-term consequences."
The positive changes
The outlook is quite pessimistic, but some progress has been made in environmental matters according to scientists, two stand out:
- reduction of chemicals that damage the ozone layer and
- increase in energy generated from renewable sources.
In some regions there has been a “rapid decline in birth rates, which can be attributed to investments in women's education” and there has also been a slowdown in deforestation rates in some places.
The bad news
Among the risk situations, the article highlights the problem of fresh water, which has decreased by 26% available "per capita"; a decline in fish catches, despite increased fishing efforts, or a 75% increase in ocean dead zones.
The deforestation already suffered by the planet is also worrying. Some 122,000 million hectares of forests have been lost globally in order to install agricultural activities, the continuous increase in global carbon emissions and rising temperatures.
The Alliance of World Scientists also highlights the 35% increase in the human population, while there is a collective reduction in biodiversity of 29% in the number of mammals, reptiles, amphibians, birds and fish.
