Even so, while cardboard definitely counts as green packaging, it has environmental drawbacks. When it’s dumped into landfill sites, its biodegradation emits methane gas, creating a substantial carbon footprint. Moreover, it’s made of tree fibres, so it adds to the r...
aPlants which occur where you do not want them are called weeds. Gases that occur where you do not expect or want them are considered stray gases. The most common stray gases are methane (CH4) and carbon dioxide (CO2). Stray gases may be naturally occurring, or they may be man-made....
As many seamounts result from volcanic or tectonic activity, some are known to degas and vent reduced compounds such as methane and sulfide41. Such active seamounts can support the establishment of chemosynthetic communities and locally enhanced microbial growth42. In the present study, we did not...
