Answer:The easiest approach to define environmental footprints would be to describe the impact of human activities in terms of the area of biologically productive earth, water and waste production.
Explanation:The Ecological Footprint quantifies the biologically productive land needed to meet the demands of nature: fruit and vegetables, meat, fish, wood, cotton and other fibres, as well as absorption of carbon dioxide from the burn of fossil fuel and the room for buildings and roads.
A. The spelling of the two words might be similar and some sounds might be the same.
Although it is possible for words in two different languages to have the same spelling and/or pronunciation, it is much more likely that they would be similar. Since, the languages are derived from the same root and belong to the same family, it would make sense that the words would be similar, if not exactly the same.

Answer:
The Paleozoic Era, which ran from about 542 million years ago to 251 million years ago, was a time of great change on Earth. The era began with the breakup of one supercontinent and the formation of another. Plants became widespread. And the first vertebrate animals colonized land.
Life in the Paleozoic
The Paleozoic began with the Cambrian Period, 53 million years best known for ushering in an explosion of life on Earth. This "Cambrian explosion" included the evolution of arthropods (ancestors of today's insects and crustaceans) and chordates (animals with rudimentary spinal cords).
In the Paleozoic Era, life flourished in the seas. After the Cambrian Period came the 45-million-year Ordovician Period, which is marked in the fossil record by an abundance of marine invertebrates. Perhaps the most famous of these invertebrates was the trilobite, an armored arthropod that scuttled around the seafloor for about 270 million years before going extinct.
