Thai Elephants
Elephants have traditionally been used as working animals in Thailand,
especially for the logging industry in the northern part of the country.
In 1989, however, logging was banned because of concerns about deforestation,
leaving the animals and their owners without work.
Meanwhile, the tourism industry has ( 1 ).
Desperate to make money, many elephant owners now offer sightseers the chance to ride their animals or watch them perform tricks.
It is estimated that over 2,000 elephants in Thailand are involved in such work today.
Working elephants are considered “domesticated” in Thailand.
Truly domesticated species, such as dogs and horses,
have been specially bred so that they inherit characteristics that make them calmer, and therefore easier for humans to control.
Elephants, on the other hand, ( 2 ). Working elephants in Thailand are no different genetically from wild elephants.
They are tamed using a method known as “the crush,” in which young animals are locked in a small space, starved, and beaten
until they obey human commands.
Sangduen Chailert is an activist who runs an elephant rescue and rehabilitation center in northern Thailand.
She believes the method currently used by trainers in Thailand to tame the animals ( 3 ).
“I do not believe elephants need to taste pain to learn how to listen,” says Chailert, who points out
that the harsh practice can make elephants aggressive and dangerous.
Her gentle training methods have won her fame throughout the world.
Though her facility can assist only a small number of elephants, her work has raised global awareness of the issue.

Dam Removal
Of the approximately 85,000 dams in the United States today,
only about half are still used to supply water for agriculture or to generate electricity.
As these dams continue to affect the environment by blocking the movement of fish and preventing them from breeding,
a policy of removing the dams has become common. Several decades ago, though, ( 4 ).
Only recently has the negative impact of dams come to be seen as greater than their economic benefits.
This shift in opinion has led authorities to approve an increasing number of dam removal projects.
In 2009, the U.S. Forest Service decided to remove the Hemlock Dam on Trout Creek in Washington State
so the declining fish population could recover.
( 5 ), however. The dam was blocking large quantities of mud and sand, which had built up over the years.
Simply removing the dam would likely have caused this to be carried downstream, killing the fish and other wildlife there.
Authorities spent years deciding on a solution.
Finally, pipes were installed to carry the creek's water along a different route, bypassing the dam.
As the water level behind the dam fell, trucks carried the sand and mud away and the dam was finally removed.
The project appears to have been a success.
Many conservationists praise the results, noting that the number of fish in the creek has been increasing.
( 6 ), fish populations can vary so much from year to year that it will be a while
before scientists can determine if this trend will continue.
