This chapter addresses the biogeochemical cycles of carbon dioxide. (CO2), methane (CH4) and nitrous oxide (N2O)
Hank introduces us to biogeochemical cycles by describing his two favorites: carbon and water. The hydrologic cycle describes how water moves on, above, and below the surface of the Earth, driven by energy supplied by the sun and wind. The carbon cycle does the same... for carbon!

Forests, trees and green spaces, hereinafter ‘forests and trees’ for short, provide multiple goods and services that contribute to human health. These include medicines, nutritious foods and other non-wood forest products (NWFPs). Globally, at least 3.5 billion people use NWFPs, including medici...nal plants, which are particularly important for vulnerable groups and Indigenous Peoples and local communities (IPLCs).
During periods of crises, such as the COVID-19 pandemic, demand for forest products typically increases amongst these groups. Forests and trees also contribute to better health by playing a role in climate change
mitigation and adaptation, contributing to regulating the carbon cycle, but also moderating the micro-climate, filtering pollutants from the air and protecting settlements against the effects of extreme events such as droughts and flash floods.

There is no question that over the last thirty years environmentaldegradation and the ecological crisis have become in our day and age apredominant sign of the times. In response to this worrisome develop-ment official documents of the Roman Catholic Church, at various lev-els, have sought to addres...s the growing ecological concern from theperspective of Catholic social teaching. Consequently references to ecol-ogy and environmental issues have surfaced in papal encyclicals duringthe last fifteen years generating national and regional responses. In theUnited States, for example, the U.S. Conference of Catholic Bishops hasissued two pastoral statements on environmental issues in 1991 and2001. Significantly, the Catholic Bishops of the Pacific Northwest, rep-resenting Canada and the U.S. have also issued a unique internationalletter focused on a particular ecological region—the Columbia RiverWatershed. What all of these efforts hold in common is the attempt toapply Catholic social teaching to a new and disturbing phenomenon inhuman experience. The result has been an expansion of Catholic socialthought. What was once the “social question” has now become the socialand “ecological question.” This development, the effort to address ecol-ogy and environmental issues as ethical problems, is the focus of thispaper. In particular this paper will link environmental and humanecology with the concept of sustainability, with the intention of propos-ing an interpretation of the common good and a definition of sustain-ability within Catholic social teaching.

Agricultural ecosystems provide humans with food, forage, bioenergy and pharmaceuticals and are essential to human wellbeing. These systems rely on ecosystem services provided by natural ecosystems, including pollination, b...iological pest control, maintenance of soil structure and fertility, nutrient cycling and hydrological services. Preliminary assessments indicate that the value of these ecosystem services to agriculture is enormous and often underappreciated. Agroecosystems also produce a variety of ecosystem services, such as regulation of soil and water quality, carbon sequestration, support for biodiversity and cultural services. Depending on management practices, agriculture can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species. The tradeoffs that may occur between provisioning services and other ecosystem services and disservices should be evaluated in terms of spatial scale, temporal scale and reversibility. As more effective methods for valuing ecosystem services become available, the potential for ‘win–win’ scenarios increases. Under all scenarios, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities.

The longlist of knowledge gaps is based on existing research agendas published in 2015 or later and expert input from reviewers of the first draft of the longlist. It only includes knowledge gaps focussing on a better
understanding of the relationship between global environmental change and human h...ealth, and finding an answer to the question of how best to protect human health against these new threats.
