Net Zero: Ambitions, Actions and Uncertainties We are all aware of the effect greenhouse gas emissions is having on our planet and the efforts needed to tackle climate change. Most of us are doing our bit to minimise our impact on the environment, but despite our collective effort, are we doing enough to achieve net zero by 2050? Net zero means not adding to the amount of greenhouse gases in the atmosphere. Many countries are doing their bit by changing how they generate and use power, thereby cutting carbon dioxide output. And they announced what further steps they were going to take at the recent COP26 summit in Glasgow. In the UK, the government has been setting out its plans to achieve net zero by 2050. It’s recently announced an end date for the sale of gas boilers, which are used for heating homes. The idea is to replace them with heat pumps. It’s offering homeowners grants of up to ?5,000 to get them installed. Another initiative in the UK is a big push towards electric vehicles. There are to be financial incentives for car manufacturers, and more charging points are to be installed in streets. And there’s to be a ban on the sale of new petrol and diesel cars by 2030. But not all emissions can be reduced to zero, so those remaining will have to be compensated for, or offset. One way to do this is to plant thousands of trees, which are good at absorbing carbon dioxide. The UK government has pledged to plant 30,000 hectares of trees a year by 2025. There are other ideas too, but what’s certain is this will cost money. The CBI’s Tom Thackray told the BBC that “those costs have to be weighed up against the cost of inaction.” Whether the UK, or anyone else, reaches net zero remains to be seen. And there’s some doubt about how this can be accurately measured anyway. But it’s generally recognised that a global effort is needed to tackle climate change. Therefore, net zero targets only make sense if every other country is moving in the same direction.【缺少答案,请补充】
Is your diet making you depressed? Of all the problems that people face today, depression proves to be one of the hardest topinpoint. People often suffer secretly, not wanting to admit their need of professional help. They continue with their normal routines and, many times, unhealthy eating habits Now, health professionals are actually linking diet and depression and have found success in using diet to treat the disorder. Several researchers and Australian institutions at Deakin University in Victoria, Australia, set out to evaluate the direct link between diet and depression. They carried out the study over a 12-week period and observed 67 patients with moderate to severe depression. For their control group, the patients received social support rather than switching their eating habits to a well-balanced diet. The other patients then received dietary counseling sessions where they were advised to eat a diet high in fruits, vegetables, and lean meats. After the trial period, over 30 percent of the patients had gone into remission with their depression. Only 8 percent of the control group actually experienced this same improvement. This trial has greatly helped researchers understand and better help patients suffering from depression. Most Americans today do not associate their diet and depression together. Nearly 60 percent of Americans eat over-processed foods. 90 percent of added sugar comes from these processed foods. For people with depression, this diet might give a short energy burst, but it will eventually cause energy to sink, bringing happy moods down with it. Many people also love caffeine, drinking multiple cups each day. Again, they consume extra sugar. However, the caffeine can also disrupt sleep and cause anxiety. In addition, people with depression may have a tendency to turn to alcohol. Unfortunately, alcohol depresses the central nervous system, which will directly influence a person's mood for the worse, especially those dealing with depression. According to the research, diet and depression do go hand in hand. Those suffering from depression should do away with processed foods as much as possible. With a few simple changes in lifestyle, these patients can improve their mental health and return to normal activities with renewed energy and joy.【缺少答案,请补充】
