Adapted from "The Brook" by Alfred Lord Tennyson in Volume V. Nature of The World's Best Poetry (1904)

Come from haunts of coot and hern,
I make a sudden sally,
And sparkle out among the fern,
To bicker down a valley.

By thirty hills I hurry down,
Or slip between the ridges,
By twenty thorps, a little town,
And half a hundred bridges.

Till last by Philip's farm I flow
To join the brimming river,
For men may come and men may go,
But I go on forever.

I chatter over stony ways,
In little sharps and trebles,
I bubble into eddying bays,
I babble on the pebbles.

With many a curve my banks I fret
by many a field and fallow,
And many a fairy foreland set
With willow-weed and mallow.

I chatter, chatter, as I flow
To join the brimming river,
For men may come and men may go,
But I go on forever.

I wind about, and in and out,
with here a blossom sailing,
And here and there a lusty trout,
And here and there a grayling,

And here and there a foamy flake
Upon me, as I travel
With many a silver water-break
Above the golden gravel,

And draw them all along, and flow
To join the brimming river,
For men may come and men may go,
But I go on forever.

I steal by lawns and grassy plots,
I slide by hazel covers;
I move the sweet forget-me-nots
That grow for happy lovers.

I slip, I slide, I gloom, I glance,
Among my skimming swallows;
I make the netted sunbeam dance
Against my sandy shallows.

I murmur under moon and stars
In brambly wildernesses;
I linger by my shingly bars;
I loiter round my cresses;

And out again I curve and flow
To join the brimming river,
For men may come and men may go,
But I go on forever.

Passage 1

Ecuador, in South America, is home to 417 types of frogs and toads. Many of these species, or types of frogs, are at risk of dying out. In the last 50 years, many amphibian species have gone extinct. Salamanders, frogs, and toads are all amphibians. Amphibians are animals that spend part of their life in water and part on land, and have backbones. Amphibians must live near water. Amphibians are in trouble because their habitat is being destroyed as trees are being cut down to make room for farms and roads. Amphibians also absorb pollution easily, because they breathe through their skin. Amphibians are usually the first to disappear when an environment is under threat from pollution. Due to pollution, some frogs are born with deformed, or wrongly shaped, body parts, such as extra legs and eyes. Frogs with deformed body parts are a clue for scientists that an environment is suffering. Between the destruction of their habitats and risks to frogs from pollution, frogs are at risk of endangerment and extinction. 

Scientists are working to save amphibians from their plight. Scientists want the government to pass laws that protect amphibian habitats and limit pollution. 

Passage 2

My name is Maria and I am an amphibian conservation biologist. My job is to protect amphibians and their natural habitats, develop educational programs and exhibits to engage the public about amphibian conservation, and research to develop tools that will allow scientists to reintroduce amphibians back into the wild. Conservation biologists are scientists who study and protect animals and their environments.  I work in a zoo, but I often travel to places like Ecuador or Brazil to observe a variety of amphibians in their natural habitats. Brazil, for example, has 1,022 different types of frogs, toads and salamanders! In my work at the zoo, I specialize in only a small portion of that number. Here in the zoo, we have many amphibians in our care because some or all of their natural habitats were destroyed.  We are not alone in our work to protect amphibians. Many people, in many kinds of jobs, are helping protect amphibians and their habitats. I partner with other scientists and lawyers, like my friend Fernanda,  to help create laws that best support the conservation, or protection, of amphibians. Fernanda is an environmental lawyer who works to create laws like the Endangered Species Act that protect wildlife and their homes. She, in turn, needs to partner with government workers who can lobby and vote to help get laws passed. Together, our goal is to work together to build a world where these amphibians have safe space to live outside of the zoo, in their natural habitat, protected from pollution or loss of space. We are working with a facility in Brazil to build protected space for amphibians to be released from the zoo and into a space where they can thrive.
