Locally Extinct Rhino Is Back in Chad

Pigs don’t fly yet, but rhinos do.

Six black rhinoceroses were flown from South Africa to Zakouma National Park in Chad last week,     1     the threatened animal with a land it has not walked on in nearly five decades.

Chad is one of several African countries that have recently     2     to start their own small black rhino populations in an attempt to protect the species from extinction. It is a participant in the African Rhino Conservation Plan, which hopes to significantly grow the number of rhinos in Africa over the next five years.

Up until the mid-20th century, black rhinos     3     the landscape of Chad, grazing (吃草) and attracting tourists. But they also attracted poachers, who hunted them for their horns, which are displayed as     4     symbols. The population of black rhinos is down 97.6 percent since I960. Some estimate that as few as 5,500 are left on the continent according to the African Wildlife Foundation.

Cathy Dean, chief executive officer of Save the Rhino, an advocacy group, said six black rhinos were not significant in the context of the 5,000 or so that exist     5    . But it’s a good sign that Chad has a safe place to house rhinos now.

According to the African Wildlife Foundation, 98 percent of the current black rhino population exists in South Africa, Zimbabwe, Kenya and Namibia. South Africa, which is     6     to 40 percent of the rhinos, has already moved some of them to other countries, like Botswana.

Zakouma National Park will be responsible for protecting the rhinos from poachers and providing them with a(n)     7     environment to live in.

Transporting the animals to create a new population is a plan that can prove effective, Ms. Dean said “Some subspecies are     8     really well, with an annual growth rate at 9 percent or even higher,” she said in an email.

But moving the rhinos to a place where they once were and no longer are isn’t enough. The population must be managed and protected, and law     9     must play a role, Ms. Dean said. There should also be biological management, guided by effective monitoring. The rhinos cannot be dropped into a(n)     10     and expected to mate.

More recent research has shown that many kinds of amphibians(两栖动物) are declining or have become extinct. Amphibians are animals, such as frogs, that live partly in water and partly on land. And they have been around for over 350 million years. They have     1     three mass extinctions, including the     2     of the dinosaurs. Why are they dying out now?

The most serious aspect of amphibian loss, however, goes beyond the amphibians themselves. Scientists are beginning to think about what amphibian     3     means for the planet as a whole. If the earth is becoming unlivable for amphibians, is it also becoming unlivable for other kinds of animals and human beings as well?

Scientists now believe that amphibian decline is due to several environmental factors. One of these factors is the     4     of habitat, the natural area where an animal lives. Amphibians are very     5     to changes in their habitat. If they cannot find the right conditions, they will not lay their eggs. These days, as wild areas are covered with houses, roads, farms, or factories, many kinds of amphibians are no longer laying eggs.

There are a number of other factors in amphibian decline. Pollution is one of them. In many industrial areas, air pollution has     6     the rain, which then falls on ponds and kills the frogs that live there. In farming areas, the heavy use of     7     on crops has also killed off amphibians. Another factor is that air pollution has led to    8     levels of ultraviolet (UV) light. This endangers amphibians, which seem to be     9     sensitive to UV light.

All these reasons for the disappearance of amphibians are also good reasons for more general     10     . These factors affect human beings, too.

Plastic “Food” Endangering Turtles

Endangered green turtles are confusing plastic for food, according to scientists. Sea turtles mostly find their food visually, by     1    the color and shape of an object to work out if it is edible. Some of their favorite foods look like plastic.

Emily Duncan, a postdoctoral researcher in marine conservation commented in a statement: “The     2    of this plastic might include things like black trash bags.”

Researchers studied 34 turtles who had washed up on the beaches of on the eastern Mediterranean island of Cyprus, and found they were     3    to pieces of plastic which looked like sheets or threads, and were black, clear or green. The team were able to look at the gastrointestinal tracts (胃肠道) of 19 turtles. All of them had eaten plastic,     4    from 3 to 183 pieces in total.

Smaller turtles had eaten more plastic than bigger animals. That could be because of their naivety. The team concluded that green turtles,     5    younger individuals, who feed in the coastal waters of Cyprus, regularly     6    and eat plastic so much that the vast majority of animals contain some plastic in their gastrointestinal tracts at the time of their death.

The findings     7    past studies which show other species of turtle get mixed up between food and waste.

The problem doesn’t just affect green turtles. Extremely high     8    of plastic are found in oceans across the world, leading to all sea turtles, at least 36 percent of sea birds, and many fish species being found to have taken in plastic waste.

Professor Brendan Godley, who leads the Exeter Marine research strategy at the University of Exeter and co-authored the work, commented: “Research like this helps us understand what sea turtles are eating, and whether certain kinds of plastic are being     9    more than others.”

It’s important to know what kinds of plastic might be a particular problem, as well as highlighting issues that can help     10    people to continue to work on reducing overall plastic consumption and pollution.
