    It is natural for species of animals to become extinct over millions of years. But over the past 200 years, humans have caused the process to speed up. In recent years, the total number of threatened animal species has increased from 5205 to 5345. In most cases this is a result of human activity. How are people speeding up the process of animal extinction?

    First of all, people threaten the survival of animal species by destroying their habitats. As the human population grows, people keep building houses and factories in fields and woods. As they spread over the land, they destroy animals' homes. If the animals can't find a place to live, they die out. Sixteen kinds of Hawaiian birds have become extinct for this reason.

    Overhunting is another way that humans are causing some animals to become extinct. In some parts of the world, the parts of rare animals are worth a lot of money. For example, some people will pay more than $3,000 for a single rhino horn. This encourages hunters to kill rhinos even though the animal faces extinction.

    Humans are also polluting the air, water and soil. The effect of pollution on animal species can be complicated. For example, when waste from factories is dumped into rivers, the rivers become polluted. The fish that live in the rivers are poisoned, and the birds cannot lay strong eggs. And some, such as brown pelicans, have become rare and may die out.

    Finally, when humans introduce new species into certain environments, the animals that already live there become threatened and face extinction. For example, when European settlers brought rabbits and foxes to Australia, they killed off many native Australian animals, including the bandicoots. Eventually, the rabbits took over the bandicoot habitats. Now bandicoots are threatened with extinction in their own land.

    Every country in the world has a flag. A flag is a piece of cloth with a picture or pattern on it. The flag is a symbol that stands for the country. It is a custom in many places for people to fly or hang a flag. The flag tells something about the country and its culture. This may be about its land, its history, or the things that the people do there.

    Many flags have patterns of stripes (条纹). The flag of Italy has a green stripe, a white stripe and a red stripe. Each stripe tells something about Italy. The white stripe is symbol of Italy's snowy mountains. Some flags show pictures. The flag of Canada has a picture of a red maple (枫叶) leaf, which is a symbol of the maple trees in Canada. The Mexican flag has both a pattern of stripes and a picture. The picture shows an eagle eating a snake. This picture comes from a very old Mexican story.

    A flag may also tell about a country's past. The American flag is called the Stars and Stripes. It has pattern of fifty stars and thirteen stripes. The fifty stars are a symbol of the fifty states in the country and the thirteen stripes are a symbol of the country's first thirteen colonies (殖民地).

    However, a flag may be a symbol of a group, a school or an event like the Olympics. The flag of the Olympics shows five rings of different colors that connect. Each ring is a symbol for a part of the world that joins in the Olympics. The Red Cross is a group that helps people who are in trouble. If a person sees the Red Cross flag, which has a red cross against a white background, he knows he can ask for help. People may fly a flag as a custom on a holiday. Children's Day in Japan is a holiday when the country wishes for children's happiness. It is a custom on this day to fly a flag with a picture of a fish.

Whatever happened to the fight of carbon capture?

Debates have been going on around the subject of carbon capture. Scientists, especially engineers and geologists, have strongly criticized green groups who claimed that carbon capture and storage (CCS) schemes are costly mistakes.

The scientists insisted that such schemes are vital weapons in the battle against global heating. They also wan that failure to set up ways to trap and store carbon would make it impossible to meet the emissions target by 2050." CCS is going to be the only effective way in the short term to prevent our steel industry, cement manufacture and many other processes from continuing to pour emissions into the atmosphere," said Professor Stuart Haszeldine, of Edinburgh University. "If we are to have any hope of keeping global temperature increases down below 2 degrees Celsius, we desperately need to develop ways to capture and store carbon dioxide."

Green groups claimed CCS would not make "a meaningful contribution to 2050 climate targets". They say CCS was not a reliable way to decarbonize the energy system and that CCS has a "history of over-promising and under-delivering". Instead, they urged the construction of more renewable energy plants to be given priority.

But the claims were dismissed by engineers and geologists, "These claims are quite unfair" said Michael Stephenson, director at the British Geological Survey. "The technology behind carbon capture and storage is fully mature. It offers us a genuine solution to some of the problems we face in trying to deal with global warming."

A government spokesman for the Department of Energy and Climate Change said, "We are committed to meeting our climate change targets in a way that is affordable and provides secure energy to families and businesses. We are considering the role that CCS could play in decarbonization of the UK. But we also need to take government spending into account. CCS had better come down in cost."

What Is a Superiority Complex?

A superiority complex is a behavior that suggests a person believes they are somehow superior to others. People with this complex often have overstated opinions of themselves. They may believe their abilities and achievements are better than those of others. However, the complex is believed to be a defense system for feelings of inadequacy that we all struggle with.

It is unclear why a person develops a superiority complex. Multiple incidents may be the root cause. For example, it may be the result of many failures. A person tries to complete a specific goal or achieve a desired outcome, but they don't succeed. They learn to handle the anxiety and stress of the failure by pretending to be above it. If they feel protected from their failures in this way, they may repeat this behavior in the future.

These behaviors can begin at an early age. When a child is learning to cope with challenges, they may learn to control feelings of inadequacy or fear. A superiority complex may develop. Likewise, it may also happen later in life. As teens and adults, a person has many opportunities to try new things among new people. If these situations are not successfully coped with, a person may develop a superiority complex to overcome feeling isolated.

People with a superiority complex are unlikely to be a threat to anyone's physical health. However, the continuous lies and overstatements can become annoying to others and may negatively affect relationships. It can push away other people in your life and shrink your social circle. If you are in a relationship with a person who you think has the issue, encourage the person to seek help. For example, never hesitate to reach out to mental health professionals. They can find healthier ways to deal with hidden feelings.
