High temperatures, intense weather phenomena, drought: the climate crisis threatens to put one third of world food production at risk. Many realities that are located between the Tropic of Cancer and Capricorn could suffer the devastating effects of overheating and no longer be able to support either crops or livestock.
But this is only one side of the problem.
Massive food production is speeding up the climate crisis, global warming and melting ice. This happens because a considerable amount of energy and raw materials is needed to produce food: this translates into an increase in CO2 emissions into the environment.
The study: Mitigation of emerging implications of climate change on food production systems, published on the Mitigation of emerging implications of climate change on food production systems, said about the issue: "Crops, livestock and seafood are major contributors to global economy.
Agriculture and fisheries are especially dependent on climate.
Thus, elevated temperatures and carbon dioxide levels can have large impacts on appropriate nutrient levels, soil moisture, water availability and various other critical performance conditions.
Changes in drought and flood frequency and severity can pose severe challenges to farmers and threaten food safety.
In addition, increasingly warmer water temperatures are likely to shift the habitat ranges of many fish and shellfish species, ultimately disrupting ecosystems.
In general, climate change will probably have negative implications for farming, animalry and fishing. of climate change must be taken into account as a key as pect along with other evolving factors with a potential impact on agricultural production, such as changes in agricultural practices and technology; all of them with a serious impact on food availability and price.
This review is intended to provide critical and timely information on climate change and its implications in the food production / consumption system, paying special attention to the available mitigation strategies.
Melting ice could release unknown pathogens
Melting ice could release unknown pathogens.
The cause of global warming is the increase in ever-increasing emissions in the earth's atmosphere of particular gases responsible for the greenhouse effect, called greenhouse gases, of mainly anthropogenic origin. Glaciers, during their formation, can trap microorganisms inside them, freezing them.
If a layer of ice has recently been created, we will find more recent organisms trapped inside, while in a layer of ancient formation we will find ancient microorganisms. The melting ice can then release the microbes that have previously hibernated there, however, the mere water that is formed is not a favorable survival environment for many species.
Many organisms are more likely to survive hibernating in permafrost. The microorganisms frozen in the soil are in the absence of oxygen and in the dark, a perfect environment for their preservation, and being the composition of the permafrost different depending on the area of formation, it is possible to have a wide range of soils suitable for the survival of different organisms.
In the Arctic ice there are not only organisms that have remained frozen, despite the extreme temperatures and conditions it is still possible to find those who manage to survive. In the local microbial fauna it is possible to find some viruses and bacteria.
Many of these microbes are extremophiles, due to their ability to live in extreme environments, such as Arctic ice or volcanic waters. Fortunately, it is almost impossible that microbes suitable for living in such conditions could also be pathogens.
These viruses, so called because they are visible under a normal optical microscope, date back to about 30,000 years ago and seem to have an unusual resistance. In fact, the species found have returned to active infectious agents, luckily their target is only the amoebas.
Although there is no concrete proof today, there is a fear of the appearance of some ancient virus, perhaps of the first hominids able to awaken from the ice.
