The irruption of the COVID-19 pandemic has raised concerns on sustainability issues. The pandemic has accelerated the implementation of technologies such as ICT and shifts in mobility behaviour. Such changes have the potential to reduce environmental burdens, but also to trigger large environmental rebound effects. This perspective article reflects on some emerging concerns on the socio-economic effects of a pandemic on the environment from a rebound effect perspective. Although the pandemic offers potential to improve the environmental conditions, it brings also a high risk to produce Jevons' Paradox, i.e., increase environmental burdens rather than decrease them, as initially expected. Governments should be aware of these risks and assess the possibility to implement additional measures, like environmental taxation or limiting the use of resources, to help achieving sustainability targets.Emergence of COVID-19 joins a collection of evidence that local and global health are influenced by human interactions with the natural environment. Frameworks that simultaneously model decisions to interact with natural systems and environmental mechanisms of zoonotic disease spread allow for identification of policy levers to mitigate disease risk and promote conservation. Here, we highlight opportunities to broaden existing conservation economics frameworks that represent human behavior to include disease transmission in order to inform conservation-disease risk policy. Using examples from wildlife markets and forest extraction, we call for environment, resource, and development economists to develop and analyze empirically-grounded models of people's decisions about interacting with the environment, with particular attention to LMIC settings and ecological-epidemiological risk factors. Integrating the decisions that drive human-environment interactions with ecological and epidemiological research in an interdisciplinary approach to understanding pathogen transmission will inform policy needed to improve both conservation and disease spread outcomes.We offer preliminary evidence drawing on a novel dataset of corporate bonds issued in the European energy sector since January 2020 in combination with the European Central Bank's (ECB) purchases under the Pandemic Emergency Purchase Programme (PEPP) in response to COVID-19. We show that the likelihood of a European energy company bond to be bought as part of the ECB's programme increases with the greenhouse gas (GHG) intensity of the bond issuing firm. We also find weaker evidence that the ECB's PEPP portfolio during the pandemic is likely to become tilted towards companies with anti-climate lobbying activities and companies with less transparent GHG emissions disclosure. Our findings imply that, at later stages of the COVID-19 recovery, an in-depth analysis may be necessary to understand if, and if yes why, the ECB fuelled the climate crisis.The COVID-19 imposed lockdown has led to a number of temporary environmental side effects (reduced global emissions, cleaner air, less noise), that the climate community has aspired to achieve over a number of decades. However, these benefits have been achieved at a massive cost to welfare and the economy. This commentary draws lessons from the COVID-19 crisis for climate change. It discusses whether there are more sustainable ways of achieving these benefits, as part of a more desirable, low carbon resilient future, in a more planned, inclusive and less disruptive way. In order to achieve this, we argue for a clearer social contract between citizens and the state. We discuss how COVID-19 has demonstrated that behaviours can change abruptly, that these changes come at a cost, that we need a 'social mandate' to ensure these changes remain in the long-term, and that science plays an important role in informing this process. We suggest that deliberative engagement mechanisms, such as citizens' assemblies and juries, could be a powerful way to build a social mandate for climate action post-COVID-19. This would enable behaviour changes to become more accepted, embedded and bearable in the long-term and provide the basis for future climate action.The coronavirus crisis has opened up a window of opportunity for transformation. This should be used without getting off the regulatory track. Green recovery programs must not be reduced to a mere competition for green subsidies. Abandoning barriers to green investments and imposing a carbon price are equally important. selleck kinase inhibitor Where economically sensible, green subsidies should contribute both to stabilizing the economy and mitigating climate change. Moreover, smart green recovery programs may contribute to raising revenues for the additionally necessary public expenditures.Rebuilding G20 economies after the COVID-19 pandemic requires rethinking what type of economy we need and want in the future. Simply reviving the existing 'brown' economy will exacerbate irreversible climate change and other environmental risks. For G20 economies, investing in a workable and affordable green transition is essential. A good place to start is learning what worked and what did not from previous efforts to green the economic recovery during the 2008-2009 Great Recession, examining the cases of the United States and South Korea. Policies for a sustained economic recovery amount to much more than just short-term fiscal stimulus. Transitioning from fossil fuels to a sustainable low-carbon economy will require long-term commitments (5-10 years) of public spending and pricing reforms. The priorities for public spending include support for private sector green innovation and infrastructure, development of smart grids, transport systems, charging station networks, and sustainable cities. Pricing carbon and pollution, and removing fossil-fuel subsidies, can accelerate the transition, raise revenues for the necessary public investments, and lower the overall cost of the green transition. Garlic ( L.) is a common herb consumed worldwide as functional food and traditional remedy for the prevention of infectious diseases since ancient time. Garlic and its active organosulfur compounds (OSCs) have been reported to alleviate a number of viral infections in pre-clinical and clinical investigations. However, so far no systematic review on its antiviral effects and the underlying molecular mechanisms exists. The aim of this review is to systematically summarize pre-clinical and clinical investigations on antiviral effects of garlic and its OSCs as well as to further analyse recent findings on the mechanisms that underpin these antiviral actions. PubMed, Cochrane library, Google Scholar and Science Direct databases were searched and articles up to June 2020 were included in this review. Pre-clinical data demonstrated that garlic and its OSCs have potential antiviral activity against different human, animal and plant pathogenic viruses through blocking viral entry into host cells, inhibiting viral RNA polymerase, reverse transcriptase, DNA synthesis and immediate-early gene 1(IEG1) transcription, as well as through downregulating the extracellular-signal-regulated kinase (ERK)/mitogen activated protein kinase (MAPK) signaling pathway.
