In 2015, the 193 Member States of the United Nations agreed upon a blueprint to end poverty, fight inequality, and protect the environment. Governments promised to meet 17 global sustainable development goals by 2030, thus establishing the Sustainable Development Agenda and a to-do list for people and planet. With only 10 years left until the deadline, assessing the progress towards the achievement of the UN Sustainable Development Goals (SDGs) is of the utmost importance to guide policy development and implementation.
Climate change is reshaping our planet—not only in its physically measurable aspects, but also in terms of humanitarian challenges. Melting glaciers, rising seas, flooding, heat waves and the like are accompanied by human displacement and migration, changes in the occurrence of infectious diseases and—as highlighted by a recent study—the intensification of global economic inequality over the past half-century.

Can you imagine our beautiful planet becoming a “plastic planet”? In the BBC documentary film Blue Planet II, members of the producing team noted that plastic waste is ubiquitously floating in the sea, including fishing lines, plastic packages, and plastic bottles. Marine organisms can be trapped by plastic waste that is everywhere in the oceans, even in the deepest and most remote parts. So it is essential to carry out intensive studies of plastic waste. Large plastics can either be physically or chemically broken into fragments after having been in the water a long time, traveling long distances. Such fragments, coupled with ones that were released into seas as fine plastic particles (smaller than 5 mm), are collectively called microplastics.

The expansive and opaque offshore system used for tax-dodging all around the world — and detailed in the leaked classified files known as the “Panama Papers” and “Paradise Papers” released in the past few years — is responsible for significant losses of tax revenues, currently estimated at around US$500 billion annually. This offshore system, which includes a variety of so-called tax havens and is used by wealthy individuals, companies, and financial institutions, causes serious concerns related to the global economy and has a tremendously negative effect on the global fight to end poverty.
The following post is one of a series previewing the research that will be presented at the SETAC Europe Annual Meeting in Rome, Italy (13-17 May 2018).

How do toxic natural compounds such as microalgae toxins or plant secondary metabolites affect water quality, ecosystem functioning, and human health? For the majority of natural toxins—of which there are at least 25,000 different compounds—we do not know! Natural toxins include some of the worlds’ most toxic substances. Continue reading →
Air pollution is defined by the World Health Organization as the “the world’s largest single environmental health risk” and causes millions of premature deaths annually. Exposure to air pollution is associated with respiratory diseases (including asthma and changes in lung function), cardiovascular diseases, adverse pregnancy outcomes (such as preterm birth), and even death. In 2013, the World Health Organization concluded that outdoor air pollution is carcinogen to humans. In other words, air pollution is an invisible killer—may not always be visible, but it can be deadly. Continue reading →
What are the emerging issues that will likely affect global diversity, ecosystem services, and conservation efforts in 2018? Results from the 9th annual horizon scan, conducted by 24 experts and described in a recently published study, identified early signs of the 15 top future challenges and trends related to themes that include new mechanisms driving the emergence and geographic expansion of diseases, innovative biotechnologies, reassessment of global change, and the development of strategic infrastructure to facilitate global economic priorities.
