Coral reefs (珊瑚礁) as underwater walls can help reduce the effects of hurricanes on coastal communities. This seems unbelievable. It is reported that scientists have discovered that coral reefs are even more effective than man-made sea walls under the water. However, coral reefs are especially easy to be influenced by climate change. Overfishing and pollution have also proved very dangerous to them. Since 1950, half of the world's coral reefs have already been lost. To protect our communities and keep sea ecosystems alive, we need to protect coral reefs right away.
Let's take a closer look at how coral reefs protect us from floods, and how scientists are 1restoring (修复) reefs.
The roles that coral reefs play as underwater walls have long been recorded by scientists. During a Category 3 hurricane in 2015 in Australia, the coral reefs effectively protected the eastern shoreline from flooding. In contrast, the western coasts without coral reefs suffered serious damage. The researchers observed that the shape of coral reefs can break the approaching waves. More recently, researchers at the University of Miami have reached the same conclusion. They used a special lab simulator (模拟装置) to recreate ocean conditions during a Category 5 hurricane. They found that coral reefs could reduce the impact of waves by up to 95 percent!
Because of higher ocean acidity (酸性) and temperature, coral reefs are disappearing and dying out. At the same time, climate change puts weakened coral reefs under more stress. The University of Miami researchers are testing to plant new coral reefs while others are actively looking for effective methods to reduce the acidity of sea water. The governments have also paid more attention to these actions and provided enough money for reef restoration. With these efforts, we may address climate threats to coral reefs and they can carry on protecting our communities.
Childhood is a happy time, right? Not necessarily. Consider these facts.
Depression(抑郁症) may occur in as many as 1 in 33 children.
Once a child has an episode of depression, he or she has a 50 percent chance of experiencing another episode in the next 5 years.
Suicide(自杀) is the 6th leading cause of death for 5-to-15-year-olds.
If your child experiences 5 or more of these signs or symptoms for at least 2 weeks, he or she may be experiencing depression or mental illness.
Feeling--Does your child demonstrate: Sadness Emptiness Hopelessness Guilt Worthlessness Lack of enjoyment in everyday pleasures | Thinking--Is your child having trouble: Concentrating Making decisions Completing schoolwork Maintaining grades Maintaining friendships |
Physical problems--Does your child complain of Headaches Stomachaches Lack of energy Sleeping problems ( too much or too little) Weight or appetite changes ( gain or loss) | Suicide risk--Does your child talk or think about: Suicide Death Other morbid(生病的) subjects |
Behavior problems--Is your child: Irritable Not wanting to go to school Wanting to be alone most of the time Having difficulty getting along with others Cutting classes or skipping school Dropping out of sports, hobbies or other activities Drinking alcohol or using drugs |
Sometimes, a child who causes problems at school or at home may actually be depressed, according to the American Academy of Child and Adolescent Psychiatry.
If you think your child may be depressed, it's important to have your child treated. Discuss your child's problems with his or her doctor. The doctor may suggest a referral to a children's psychologist or psychiatrist.
