Artificial Christmas Tree
An artificial Christmas tree is an artificial pine or fir tree manufactured for the specific purpose of use as a Christmas tree. The earliest artificial Christmas trees were wooden, tree-shaped pyramids or feather trees, both developed by Germans. Most modern trees are made of polyvinyl chloride (PVC) but many other types of trees have been and are available, including aluminum Christmas trees and fiber-optic illuminated Christmas trees. History The first artificial Christmas trees were developed in Germany during the 19th century, though earlier examples exist. These "trees" were made using goose feathers that were dyed green.Forbes, Bruce David. ''Christmas: A Candid History'',Google Books, University of California Press, 2007, pp. 121–22, () The German feather trees were one response by Germans to continued deforestation in Germany. Developed in the 1880s, the feather trees became increasingly popular during the early part of the 20th century.John, J. ''A Christmas Compend ...

Carbon Dioxide Removal
Carbon dioxide removal (CDR), also known as negative emissions, is a process in which carbon dioxide gas () is removed from the atmosphere and sequestered for long periods of time. Similarly, greenhouse gas removal (GGR) or negative greenhouse gas emissions is the removal of greenhouse gases (GHGs) from the atmosphere by deliberate human activities, i.e., in addition to the removal that would occur via natural carbon cycle or atmospheric chemistry processes.IPCC, 2021Annex VII: Glossary atthews, J.B.R., V.
