Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
Answer: The glacial-interglacial cycle is triggered by changes in Earth's orbit around the Sun, and, as a result, there is approximately 100,000 years between interglacials (or glacials).
Explanation:
Siberia covers the majority of Russia
Snow and ice cover less of the Earth's surface as a result of melting due to an increase in global temperature, which also lowers albedo. More energy is absorbed due to the decrease in albedo, which leads to increased warmth and melting.
Global temperature is significantly influenced by the equilibrium between the amount of solar energy reflected and absorbed by the Earth's surface. Snow, ice, and water on Earth have different capacities to reflect and absorb solar energy, and melting polar ice triggers a positive feedback loop that hastens global warming.
Pollution, including soot, decreases the albedo of ice and speeds up melting.
