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.”

With the development of the computer, virtual reality comes into our life. If something is virtual, then it is created by computer technology and appears as if it were real. VR is a computer system with a special headset. When you put on the headset, you will look at two tiny television screens. They are so close to your eyes as if you see just one picture and you will believe that you have entered a different world. In many systems, you also wear special gloves. With the gloves you can reach out and touch things in the unreal world.
The first VR games, which have already sold round the world, enable you to drive a sports car, fly a plane, or fight an enemy. In the future, it may be difficult to tell the virtual world of the games from the real world outside. However, VR is not just for entertainment. One day, delighted children will be able to learn geography by observing exciting foreign countries without having to leave their classrooms. They will be excited to learn history by visiting the pyramids of Egypt. In addition, businesses will be able to use VR for many tasks. Pilots will be able to practise flying virtual planes before they go into the air. VR can help us in hundreds of ways improve the world.
However, some people have warned that there could be dangers. It might be dangerous if we do something wrong, or if people do not want to return to reality because it is safer than real life. Besides, we will forget how to live and work with real people.
There will be some problems with VR, as it is new for us. However, one thing is for sure: VR is here to stay. Get ready to step into another world!

Virtual Fitness
Exercise plays a very important role in a healthy lifestyle. But you may not have time or money to go to a gym on a regular basis. The good news is that today's technology lets you access fitness classes from the comfort of your home. A quick Internet search will turn up thousands of online fitness classes. You can watch videos on your phone, computer or tablet and do the exercises right where you are. All you need is an Internet connection and a space large enough to move around in.
Online fitness classes take a wide variety of forms. Some focus on stretches and slow movements. Other classes involve fast aerobic activity, while others build muscle strength. Some require equipment such as weights, but others use only your body. This means that you can choose a class that does what you like. And you can try a different one whenever you like.
Anyone can post a fitness video on the Internet. Not everyone knows what they are doing. So it is important to think about who is teaching the class. Try to find teachers who are certified by an organization with a good reputation. I tried some virtual fitness classes several years ago.The reason was simple: convenience. I could do a fitness class at any time of day. I didn't need to travel to a gym and back, which saved me a lot of time. But being able to work out any time meant I kept putting it off. I'd do everything else first and then the day would be over. I’d never actually get around to exercising.
Having to exercise at a definite time means I have to put it on my schedule. So for me, scheduled classes such as those at a gym are helpful.
Anyhow,if the gym isn't for you, you may want to give an online fitness class a try.

Yours,

It was a pleasant morning. Meena was leaning out of her window and feeding the birds. The roads were empty because of COVID-19 lockdown. Just then a strong blow of wind came and Meena saw something flying in the air from distance. “Is it a kite?” Meena thought. As it came closer, Meena saw that it was a mask.
Curious to know where the mask came from, she ran to catch the mask and finally ran to the beach nearby. The mask fell into the sea water. As Meena looked around, she saw many masks floating in the sea and lying on the beach. She wondered where they came from.
Suddenly Meena heard a low voice nearby so helpless as if crying out for someone for help. She went closer to the voice – it was a huge turtle from the sea, with something stuck into his mouth. Apparently the turtle was choking (噎住) and in great pain. Meena moved closer to him, without wasting any time pulling it out of his mouth – it was a mask! The turtle finally recovered from the pain and seemed to express relief from his eyes as if to say “thank you” for her kindness.
Meena was sad to see so many masks thrown around. Just then she saw a man dumping rubbish here, with many single-use masks poured out. “Stop!” she screamed. “Please don’t throw the waste here. The turtle might swallow the mask again and fall sick!” The man stopped at once. He was sorry for his actions and decided to help clean the beach. He called a few people from the village to help them clean it. In no time the beach was free of rubbish.
Meena was happy and couldn’t wait to go home and tell her mother about it. Her mother was very proud of her, and told her the importance of throwing single-use masks into a rubbish bin so that animals wouldn’t swallow them. Yet Meena was still worried. She didn’t want the turtles to fall sick again due to people’s ignorance.
