Ozone Depletion Potential

AbstractIodine deficiency represents a public health problem worldwide. To increase the amount of iodine in the diet, biofortification strategies of plants have been tried. They rely on the exogenous administration of iodine to increase its absorption and accumulation. However, iodine is not stable in plants and can be volatilized as methyl iodide through the action of specific methyltransferases encoded by the HARMLESS TO OZONE LAYER (HOL) genes. The release of methyl iodide in the atmosphere represents a threat for the environment due to its ozone depletion potential. Rice paddies are among the strongest producers of methyl iodide. Thus, the agronomic approach of iodine biofortification is not appropriate for this crop, leading to further increases of iodine emissions. In this work, we used the genome editing CRISPR/Cas9 technology to knockout the rice HOL genes and investigate their function. OsHOL1 resulted a major player in methyl iodide production, since its knockout abolished the process. Moreover, its overexpression reinforced it. Conversely, knockout of OsHOL2 did not produce effects. Our experiments helped elucidating the function of the rice HOL genes, providing tools to develop new rice varieties with reduced iodine emissions and thus more suitable for biofortification programs without further impacting on the environment.

And Function

Rising levels of ultraviolet radiation (UVR) secondary to ozone depletion are an issue of concern for public health. Skin cancers and intraepidermal dysplasia are increasingly observed in individuals that undergo chronic or excessive sun exposure. Such alterations of skin integrity and function are well established for humans and laboratory animals, but remain unexplored for mammalian wildlife. However, effects are unlikely to be negligible, particularly for species such as whales, whose anatomical or life-history traits force them to experience continuous sun exposure. We conducted photographic and histological surveys of three seasonally sympatric whale species to investigate sunburn and photoprotection. We find that lesions commonly associated with acute severe sun damage in humans are widespread and that individuals with fewer melanocytes have more lesions and less apoptotic cells. This suggests that the pathways used to limit and resolve UVR-induced damage in humans are shared by whales and that darker pigmentation is advantageous to them. Furthermore, lesions increased significantly in time, as would be expected under increasing UV irradiance. Apoptosis and melanocyte proliferation mirror this trend, suggesting that whales are capable of quick photoprotective responses. We conclude that the thinning ozone layer may pose a risk to the health of whales and other vulnerable wildlife.

The Impact

This article aims to explain the impact of global warming on public health. The mechanism that occurs is that climate change affects environmental factors such as changes in environmental quality such as water quality, air and soil, depletion of the ozone layer, decreases in the quality and quantity of water resources, loss of ecosystem function and land degradation which in the end these factors will affect human health. . Global warming has shortened the mating cycle and growth of mosquitoes from eggs to larvae and adult mosquitoes, so that the population size will increase rapidly. The impact of global warming also affects ozone depletion, among others, the increasing intensity of ultraviolet rays reaching the earth's surface causing health problems, such as skin cancer, cataracts, decreased endurance, and the growth of genetic mutations. . It is also associated with high air temperature with decreased heart rate. A low heart rate can increase the risk of a heart attack.

New Strategies

The paper is an attempt to redefine the concept of resilience in the context of changes taking place globally. One of the key changes was caused by the Covid-19 pandemic. It has shown the inadequacy of the neoliberal discourse of resilience that shifts responsibility to individuals who must be prepared to overcome the circumstances of crisis or shock. However, resilience can be seen in terms of solidarity, dignity and responsibility towards others. Resilience also implies strategies that involve large investments in public health, ecology and self-sustainable solutions to battle climate change that is causing infectious diseases. The purpose of this paper is to raise awareness of the need to start creating a set of public policies that would imply an ethical evaluation related to the success or failure of treating others responsibly.
