Animal captivity is okay in terms of ethnics.

I have looked into pros arguments and I was quite horrified by my own research. When it comes to space, pro said: "However, space in the wild is present because it is necessary: many animals are living together in one place. Cages simply divide this space up into manageable parts, each part containing one or two animals. Look at what humanity has done with houses. They are simply divisions of a large tract of land that was originally made for multiple beings to thrive in at the same time." Firstly, "humanity with houses" I have to disagree. All people crave for is real estate is space, property and territory. This drive is how civilization has grown into countries, empires, etc. We love extra elbowroom for us to wiggle about. If a billionaire had to choose between a one-room apartment, or a 120-room mansion, I put my money on the mansion. Also small captive spaces prove to drive wild animals to rebellion and starvation. "While conditions have improved from the years of bars and cages, detractors take issue with other items. Although the natural-looking habitats are certainly more attractive, people like David Hancocks, a zoo consultant and former zoo director, describe them as mere illusions, arguing that they're not much of an improvement in terms of space" "Zebras at the National Zoo in Washington D.C. starved to death because of insufficient or incorrect food, and the same zoo's red pandas died after ingesting rat poison" "In this same article, it says that some animals, like the aardvark, survive on a limited diet that zoos have a hard time fulfilling; others thrive only in certain temperatures and environments that aren't easy to recreate." When it comes to zoo conservation's attempt for reintroduction programs, out of "145 reintroduction programs" that are "carried out…in the last century, only 16 truly succeeded in restoring populations to the wild."

It says that "In the wild, orcas and dolphins swim up to 100 miles per day. (5,6) But captured dolphins are confined to tanks that may be only 24 feet long, 24 feet wide, and 6 feet deep.(7) They navigate by echolocation—bouncing sonar waves off other objects to determine their shape, density, distance, and location—but in tanks, the reverberations from their own sonar bounce off the walls, driving some dolphins insane. Jacques Cousteau said that life for a captive dolphin "leads to a confusion of the entire sensory apparatus, which in turn causes in such a sensitive creature a derangement of mental balance and behaviour." It says that high chlorine levels in their tanks can have side affects that are highly dangerous for their animals. "Dolphins at the Clearwater Marine Aquarium were unable to open their eyes, and their skin began to peel off." Another incedent is when a tank in "North Carolina Zoological Park didn't provide enough shade, causing a sea lion's eyes to develop blisters and rupture. Oklahoma City Zoo closed its dolphin exhibit after four dolphins died within two years from bacterial infections.(10) Sea lions at Hershey Park won't come out of their pen because they fear the noise made by the nearby rollercoasters.(11)" "Captivity's Tragic Consequences" "If life for captive orcas and dolphins were as tranquil as marine parks would have us believe, the animals would live longer than their wild counterparts. However, while captive marine mammals are not subject to predators or ocean pollution, their captivity is nevertheless a death sentence." "It has been documented that, in the wild, dolphins can live into their 40s and 50s.(14) But more than 80 percent of captive dolphins whose ages could be determined died before the age of 20.(15) Wild orcas can also live for decades—some have been documented to be more than 90 years old—but those at Sea World and other marine parks rarely survive for more than 10 years.(16)" This is a deep concern for all the animals that stay in captive envirnments. Example of Incident: Thirty-year-old Sharky died of head injuries when she collided in mid-air with another dolphin while forced to perform tricks as part of Florida's Discovery Cove, where tourists participate in the "Swim With Dolphins" program.(23) More details PLEASE LOOK! http://www.peta.org... http://www.peta.org... In conclusion, there are more damaging cons than positive pros. Zoos may help with research but at the price of shortened lives of these animals. Nature preserves are better because it is land that no human can live on so the animals can do what they do best, being wild. It also benefits research because we can look at them and learn about them in their natural environment.
