Trace elements are chemical elements present in low concentrations in the environment, including: (1) essential elements for plants and/or animals (such as Cu, Mn, and Zn), which sometimes cause human deficiency (frequent for Mo and Se) and toxicity when concentrations are below or above certain thresholds, respectively; and (2) elements with no identified biological role, which only cause toxicit

Chocolate manufacturers are increasingly investing in sustainable cocoa sourcing practices. Nonetheless, following two decades of sustainability initiatives in the cocoa sector, numerous severe, intractable, and often interrelated environmental, social, and economic sustainability challenges remain.

Grasslands cover about one-third of the global ice-free land surface and deliver crucial ecosystem services. The state of grasslands and the balance between provisioning and regulating ecosystem services are largely determined by grassland use intensity. A better characterization of grassland production systems is essential to evolve toward more sustainable grassland management.

Small bodies in the Solar System hold an exciting position in the family of celestial bodies, as they might play a key role in understanding the formation of our heliocentric system, and, ultimately, life. Unlike (terrestrial) planets and larger natural satellites (moons), small bodies have experienced far less transformation, comparing today's state with theirs state in the early Solar System.
