The World Wildlife Fund (WWF) says more than half of the world’s wildlife population has been lost, which the conservation group says has placed the health of the planet at risk.
The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.
The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop in Latin America.
Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is about converting forests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”
The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.
“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2 than the natural systems can actually absorb, which is clearly not sustainable.”
Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.

How Can I Fight Laziness?
Lazy people will never amount to anything in life. However, laziness can be defeated once a few changes have been made in your mind.
1. Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency to put off things. By adjusting your sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.
Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from task to task. Others take a more proactive approach, viewing each task as a challenge they must overcome alone. 2.
Some people fight laziness by removing the temptations(诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. 3. complete a few tasks and reward yourself with what you enjoy, such as a good dinner or a film. Laziness can also be a lasting problem at home. Couples and children may all have different energy levels, but laziness can be spread if not dealt with immediately. 4. Be the first to collect and wash dishes after a meal. Others in the home may eventually follow your example and perform their own task. It is difficult to practice laziness when you are surrounded by motivated people.
5. enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help lift your spirits.
A. To fight family laziness, set an example.
B. Knowing how to fight laziness is important.
C. One way to fight laziness is to get enough sleep.
D. Finally, taking exercise regularly can help you fight laziness.
E. With strong determination, you will be able to achieve your goal.
F. Laziness sets in when you no longer feel in charge of your own life.
G. Create a reward system for yourself, just as parents do for the children.

At just 18 years old, Canberra student Lochie Ferrier has already conducted research in a frontier field — aerospace engineering. Aerospace engineering is the primary of engineering concerned with the science and technology of aircraft and spacecraft.
In 2014, he was one of 80 high school students worldwide who a six-week science and engineering program at MIT. During the program, he was by the institute’s scientists, and developed a method to identify inactive satellites. This method, called OASIS, is designed a way to help manage space debris(碎片), which operating satellites.
“One solution to this problem is a robot that can gather pieces of space debris and store them in orbit,” he says. “These pieces could be to new satellites later, thus the costs and launch weights of new satellites.” However, satellite identification technology would be needed for this solution, and that’s what Lochie is working on. “I hope this method would be put into practice in the near future, in the next 10 years,” he says.
Lochie has made the of the Young Innovators category of the Australian Innovation Challenge Awards with his OASIS. This category is open to students aged 21 years or and carries a $ 5,000 prize. If he won, he would use the money to help fund research into OASIS. “My plan for using the money would be to try to use materials which could stand up to the environment of space,” he says.
He is also considering how to the technology to organizations such as NASA and satellite manufacturers.
Lochie’s in aerospace engineering was aroused by the big dish antenna(碟形天线)at NASA’s tracking station near Canberra,which he visited in his early teens. He said his software design and development teacher at Canberra Grammar School him, too. “He taught me valuable project management and skills which I applied to OASIS.”
Lochie has been attending Canberra Grammar School and will soon exams for admission to universities. He his time between schoolwork, his personal projects such as OASIS and the development of apps, rock climbing, and playing classical violin. The teenager is well on his way to realizing his sky-high ambition.
