Overall I conclude that Mass Media does have an effect of society.
From taking you to a far off land to teaching you about the intricacies of the life inside a colony of ants, to surfing the Internet for a new chat group to join, we learn and experience things and events that no humans ever before in history have experienced through this miracle we call mass media....
What are the influences of mass media in our society.
Larger brains had to confer immediate advantages or else they would not have evolved, especially as energy-demanding as they are. Evolutionary pressures ensure that there is no cost without an immediate benefit. As humans have demonstrated, intelligence combined with manipulative ability led to a domination of Earth that no other organism ever achieved. Humans weigh about 50% more than chimpanzees, but have brains three times the size. A human brain comprises about 2% of the body’s mass, but uses nearly 20% of its energy at rest. Growing an energy-demanding organ was funded with the coin of energy. How did protohumans manage it?
Sauropods seem to have . Until relatively recently, animals as agents of ecosystem change and maintenance was a marginal idea. But today, is thought to be a seminal geophysical event in the Cambrian, and those huge sauropods probably had an ecosystem impact like what elephants have today in Africa. Elephants today break up woods as they feed, as they knock over trees and uproot them. That damage transforms the biome and provides opportunities for other kinds of herbivores and their predators. Elephants also and are considered , which have an outsized impact on their environment. Today, there is a “” to the overkill hypothesis regarding megafauna extinctions soon after humans appeared; such people minimize the impact of humans (their position has an inherent conflict of interest, as those ) and attribute the extinction of elephants of the Western Hemisphere (, ) to climate change and resulting changes in vegetation. If the current situation with African elephants is relevant, it is likelier that those vegetation changes were a of elephant extinction, not a cause. Elephant extinctions would have affected many other kinds of plants and animals, and could have precipitated . Similarly, those huge sauropods would not just have nibbled at vegetation and been relatively harmless browsers, but their vast bulk would have been ideal for pushing over trees to get at their foliage and other devastations of trees in particular, which would have dramatically impacted biomes. Giant dinosaurs probably had keystone species impacts on their environments, particularly the vegetation. Dinosaurs were not the only huge organisms in those days. The appeared in the Jurassic, and would have been immune to dinosaur browsing when they grew large enough. Below is an artist's conception of a typical Jurassic landscape (just as an allosaur and stegosaur are about to cordially interact). (Source: Wikimedia Commons)
Mass Media and their Role in Modern Times
Two primary events drove the first phase of the Ordovician-Silurian mass extinction: the ice age caused the sea level to drop drastically and the oceans became colder. When sea levels fell at least 50 meters, the cooling shallow seas receded from continental shelves and eliminated entire biomes. Many millions of years of “easy living” in warm, shallow seas were abruptly halted. Several groups were ravaged, beginning with the plankton that formed the food chain’s base. About 50% of brachiopod and trilobite genera went extinct in the first phase, and cool-water species filled the newly vacant niches. Bivalves were largely found in seashore communities, were scourged when the seas retreated, and lost more than half of their genera. Nautiloids were also hit hard, and about 70% of reef and coral genera went extinct. The retreating seas somehow triggered the extinctions, and whether it was due to simply being exposed to the air or changing and cooling currents, nutrient dispersal patterns, ocean chemistry, and other dynamics is still debated, and those extinction events are being subjected to intensive research in the early 21st century.

The twin ideas of efficiency and resilience are important. Efficiency is about getting more for less, particularly energy. Although aerobic respiration’s energy efficiency allowed for to develop, they end up creating interactions and dependencies, and the entire structure can lose its resilience when compared to simpler systems. Remove one part of the food chain and the entire ecosystem can collapse, and it can be part of the chain, from top to bottom. Making systems more efficient, as the last bits of energy are wrung from the system, reduces their resilience to the real world’s surprises. That dynamic is probably a key contributing factor of mass extinctions during the eon of complex life. Modern ecosystems studies are making the connections clear and are being applied to the dynamics of human civilizations; work has been seminal in this regard. Complex ecosystems pass through of exploitation, conservation, release, and reorganization, and three dimensions of interaction are involved: potential, connectedness, and resilience. In general, simple systems are more stable than complex ones, which is another reason why any , if there were any, would have been far less cataclysmic than those of complex life.

As with previous critical events, , life helped terraform Earth. But the late Devonian is an instance when the rise of land plants may have also had effects. , which reduced the atmosphere’s carbon dioxide concentration by up to 80%, may have cooled Earth’s surface enough so that an ice age began and another one of Earth’s mass extinctions began. As with the , the ultimate cause for the Devonian extinctions seems to have been rising and falling sea levels, associated with growing and receding ice caps, as . Devonian extinction events began happening more than 380 mya, and a major one happened about 375 mya, called the . The reasons for the Kellwasser event are today generally attributed to the water becoming cold and anoxic.A bolide impact has been invoked in some scientific circles, but .Mountain-building and volcanic events also happened as continents began colliding to eventually form Pangaea (and the resultant silicate and basaltic weathering removed carbon dioxide from the atmosphere), and those dynamics may have been the previous major mass extinction. Black shales abounded during and after the Kellwasser event, and they are always evidence of anoxic conditions and how the oil deposits initially formed. However, the Kellwasser event anoxia may have not only been due to low atmospheric oxygen, but was also the result of eroding the newly exposed land and the detritus of the new forest biomes, which created a vast nutrient runoff into the oceans that may have initiated huge that caused anoxic events near shore.
