Answer: Ecological footprint
Explanation:
Ecological footprint simply refers to the ways in which the effect of human activities are measured in terms of the area of biologically productive land and water required to produce the goods consumed and to incorporate the wastes generated. In ecological footprint, there available productive land and water needed to supply the people in a particular country or area with an endless supply of renewable resources and to absorb and recycle the wastes and pollution produced by such resource use.

Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.
Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.
