The early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood. From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes, and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. There, it moves slowly to the sea.

The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.

As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece of plastic in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.

Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.

There are many reasons why some cats are bad-tempered. It’s commonly believed that their temperament can be influenced by the way they are born or raised. 【小题1】 According to veterinarian Dr Katrina Warren, the problem can generally be solved, but you’ll need to look for underlying issues.

Changes in a cat’s behaviour can often be explained by a health problem. Pain can cause cats to behave differently. It’s easy to mistake a problem as behavioural, which in fact is medical. Should you observe a significant change in your cat’s behaviour, then a visit to the vet is the best place to start. 【小题2】 Also hiding and avoiding being touched. Be sure to report all changes to your vet. There are many health problems that can be readily treated to ease symptoms and pain for your cat.

It pays to remember that cats don’t like to share or queue. Sharing of ‘resources’ such as litter trays and foodbowls can cause stress and anxiety for many cats. It’s always a good idea to provide each cat with their own litter box, food, water bowls and bed. A lack of space to hide from or avoid other cats, competition for territory and lack of individual attention can also add to household friction. 【小题3】

Moving to a new house, the arrival of a new baby, new pets and other types of change can seriously impact cat behaviour. Cats are creatures of habit and tend to be territorial. 【小题4】 Try to keep your cat’s environment as calm as possible and ensure there are places where they feel safe.

【小题5】 These are often cats that received limited socialisation with humans when they were kittens. These cats do best in a quiet household without children and need understanding and patience to help build their confidence.

Overuse of land and warming temperatures are putting insect diversity in danger in some parts of the world, scientists reported Wednesday.

The study, published in the journal Nature, confirmed for the first time a clear and alarming link between warming temperatures and large-scale agriculture and showed that where there are more farmlands, there is a greater decrease in insects.

“These findings lead to huge concerns,” said Charlotte Outhwaite, the lead author of the study and researcher at the University College London, adding that losing insects could threaten human health and food supply.

“Three quarters of our crops depend on insect pollinators(授粉),” Dave Goulson, a professor of biology at the University of Sussex in the UK, previously told CNN. “Without insects, crops will die. We won’t have things like strawberries. We can’t feed 8 billion people.”

Outhwaite said their findings “may only show the tip of the iceberg(冰山一角),"because of the limited amount of evidence in some areas. “But I think there are also a lot of results that we probably don’t really know because there are so many different kinds of insects.” Outhwaite told CNN.

Scientists say, overuse of land has a link with warming temperatures. Destroying natural habitats for agriculture can make the temperature rise sharply. Researchers found great decreases in insect populations in areas of the world that are much warmer. They concluded that in areas with small-scale agriculture, less temperature warming, and more natural habitats, insects only dropped by 7%, compared to the 63% decrease in areas with large-scale agriculture, more temperature warming and less natural habitats. So what can we do to help prevent this?
