From Ceballos G, and his assessments Ehrlich PR, Barnosky AD, Garcia A, Pringle RM, and Palmer TM, they have strictly proven, through very narrowed, factual, precise data, that proves that the extinction rates are higher than before due to of human activity....   [tags: Extinction, Human, Megafauna, Dinosaur]

An Open Letter to Roderick Nash on Island Civilization

Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural disasters to destroy what is hurting it....   [tags: pollution, extinction, nature, disasters]

The Cause of the Dinosaur Extinction

- The Cause of the Dinosaur Extinction The biggest mystery surrounding the dinosaur is how did they die. For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc.). Some have ventured that early mammal inhabitation slowly “pushed” the dinosaurs to extinction....   [tags: Papers]

Why Extinction Does Happen It Is Not Indefinite

- However, when extinction does happen it is not indefinite. For example, Lattal,Peter,& Escobar(2015) state “That is, even though extinguished, the form of the response may remain stable or intact, at least in the short term but often in the longer term”. What this means is that even when extinction does occur the response that underwent the extinction process can recur/resurface if the reinforcer is reintroduced again.Why this is significant is because it shows how behavior can be learned and relearned all over again which is important if an individual is trying to get rid of a maladaptive behavior....   [tags: Reinforcement, Operant conditioning]
