preventing animal extinction is one of the most important and serious problems in the world today. Do you know some animals are disappearing year by year. According to an Internet article‚ 19817 animals are designated as an endangered species. Besides that 63837 species of animal are also registered on Red Book. It means the ecological food chain is breaking‚ so we have to think about how to prevent animal extinction. This essay will explain why people have to know how to prevent animal extinction because

main principle of classical conditioning is acquisition‚ first stage of learning when a response is evoked and slowly strengthened (Kendra‚ 2013). At this stage‚ NS-UCS pairings must be occurred several times or a very intense‚ tragic or aversive event with one occurrence of NS-UCS pairing could elicit a strong CR (Michael & Ronald‚ 2009). For instance‚ the person had an experience of free-fall in a lift during blackout. After that‚ when

theorists whose theories are predominately functionalistic. These theorists include Edward Thorndike‚ Burrhus Frederick Skinner and Clark Leonard Hull. The first theorist‚ Edward Thorndike proposed the theory of connectionism which linked sensory events to behavior and described the bond between stimuli and response as a connection. By conducting research with animals‚ Thorndike concluded that learning is achieved through a process of trial-and-error and that learning is incremental. He also concluded

This is demonstrated in “Zoos Are Not Prisons. They Improve the Lives of Animals.” when it’s described that “the need for intensive conservation campaigns is now more urgent then ever before: our world is currently in the midst of the ‘sixth extinction’.” Moreover‚ without human intervention‚ environments will collapse from human error. The author of “Why Zoos Are Good” explains that “reintroduction successes... are increasing and the very fact that species have been saved or reintroduced as a

gives feedback on the topic of de-extinction. According to Zimmer‚ de-extinction is defined as‚ “The notion of bringing vanished species back to life”‚ and he elaborates the pros and cons of actually completing this ordeal (31). Reading the differentiating views on the subject is very interesting‚ and caused me to think more and more as to if bringing back the extinct species is for the good or bad of our world. But as a firm believer in Christianity‚ I feel de-extinction is a sensitive subject and is

appearance‚ but most importantly there was the catastrophic extinction event of many species near the end of the Quaternary period. The event had a great effect on the species roaming on Earth. The Quaternary extinction event was caused by factors such as global climate fluctuations which pushed many to adaptation and others to extinction. It’s also plausible that hunters contributed to the Quaternary extinction by causing local extinctions. After the last ice age‚ the ecosystem was greatly impacted

ESSENTIALS OF ECOLOGY (Chapter 9) 1. Review the Key Questions and Concepts for this chapter on p. 184. What factors led to the premature extinction of the passenger pigeon in the United States? Factors that led to the premature extinction of the passenger pigeon are uncontrolled commercial hunting and habitat loss. Passenger pigeon in the 1858 became a big hunting business. Weapons like shotguns‚ traps and artilleries were used and even the burning of sulfur in suffocating the birds. These threats

As a result‚ the rapid exhaustion of the Earth’s natural resources becomes the most important issue nowadays that will cause many consequences in nature. In a word‚ some of those bad effects that human activities cause to nature are change in climate‚ species extinction‚ and marine ecosystem damage. Body Climate change

Two animals that I chose are Panthera leo spelaea known as European or Eurasian cave lion and cave bear. European cave lion lived from about 370‚000 to 10‚000 years ago. From the paintings and the fossils that have been found we can say that cave lion is much bigger that the normal lions that we know today. Rounded‚ protruding ears‚ tufted tail‚ and perhaps faint‚ tiger-like stripes are the common thing between all of the lion caves. Mountain lion was living in Europe until the last European Ice
