3 . Fashion operates on desire. We want our dressing style to be unique as well as part of a group. Such wishes can be fulfilled immediately. But to overcome such a desire we need to reflect on the fragility (脆弱) of our planet. This means there should be a better way to keep the pleasures of fashion open to all of us than promoting single-use clothes as desirable.

The fashion industry has benefited from globalization to mass-produce goods at the cost of human and environmental damage. Every year, 100 billion new pieces of clothing are produced by one out of six people worldwide. Yet, only 2% of them earn a living wage. Furthermore, the industry has for too long promoted over-consumption as a good thing. About a fifth of mass-produced clothing does not even sell and ends up being buried or burned. Clothes now account for 8% of global greenhouse gas emissions. Synthetic fibers are being found in Arctic Sea ice and in fish.

Luckily, recently the market has witnessed a new trend. New research shows that 51% of Britons tend to purchase longer-lasting clothes rather than throwaway items, up from 33% a year ago. What’s more, more brands are responding to the mood. For example, H&M and Zara have made new commitments to making clothes more environmentally friendly. John Lewis has also encouraged a culture of handing down children’s clothes.

At no other time in human history has fashion been so accessible to so many people. Technology will help fashion greener. Better regulation of supply chains will help too. There is a shift from getting rid of clothes to repairing, reusing or even renting them.

However, it is hard to see how this will be enough to make fashion truly environmentally friendly if the industry still produces more and more clothes. Obviously, more has to be done to stop the persistent demand for expansion in our society.

4 . Organic farming(有机耕作) is a farming method that uses the natural techniques to grow crops and raise farm animals. This approach avoids the use of synthetic(合成的) chemicals, pesticides, and fertilizers, and instead relies on natural methods to promote healthy soil and crop growth.

One of the key benefits of organic farming is its sustainability(可持续性). By avoiding the use of harmful substances, organic farmers are able to reduce their impact on the environment and protect the health of both the soil and local ecosystems. This also means that organic farming has a smaller carbon footprint than traditional farming methods, making it a more sustainable and environmentally-friendly option.

In addition to its environmental benefits, organic farming also has important health benefits. By avoiding the use of pesticides and fertilizers, organic farmers are able to produce crops that are free from harmful chemicals. This can lead to a healthier diet and reduced risk of exposure to harmful substances.

Moreover, organic farming can also have positive economic impacts. By supporting local farmers and promoting sustainable agriculture, organic farming can help to create more jobs and support local communities. Additionally, organic produce (农产品) is often sold at a higher price, which can provide financial benefits for farmers and help to promote sustainable agriculture as a good business model.

However, there are also challenges associated with organic farming. Because organic farming relies on natural methods to control pests and promote growth, it requires more workers and demand more time than traditional farming methods. Additionally, organic farming may not always be as productive or efficient as traditional farming methods, which can make it more difficult for farmers to meet demand.

Despite these challenges, many farmers and consumers are using organic farming as a more sustainable and environmentally-friendly way. As more people become aware of the environmental and health benefits of organic farming, it is likely that demand for organic produce will continue to grow. This, in turn, may help to promote the growth of sustainable agriculture and support the health of both people and the planet.

6 . Online scams (诈骗) are targeted at people from all walks of life.     1    , and no one can stay safe without learning how to avoid them. Here are some of the tips to keep you safe from online scams.

1. Accept that online scams exist

Every time you start dealing with an unknown person or a contact online, you must consider it a possibility that you're dealing with a scammer.     2    . Nothing in this world comes free, and everything has a price. So, if one fine morning you receive an email message about winning a million-dollar prize, chances are very high that it's an ugly trap.

2.Choose passwords carefully

You must choose difficult passwords while updating them from time to time.     3    . And always avoid using the same password for different accounts.

3. Don't click what you don't know

A classic style followed by scammers is to send you Trojan horses in emails or messages.     4    . In addition, you can use a Virtual Private Network that blocks access to bad pages and pop-ups.

4.    5    

If you ever have doubts in your mind about the intentions of an unknown person, you should first carry out an in-depth search online based on the basic information they share. If you ever receive a request for money from a friend, always call them up to check first.

7 . More than 80% of adolescents worldwide are not active enough, putting their health at risk by sitting focused on a screen rather than running about, say World Health Organization (WHO) researchers

The proportion of inadequate active girls in 27 countries rose to more than 90% in 2016, the latest year for which figures are available. There was a significant gender gap. Girls lag behind boys in physical activity, in all but four countries- Afghanistan, Samoa, Tonga and Zambia.

The WHO says the situation is serious and that urgent action must be taken to get adolescents moving, with inactivity posing a great threat to their current and future health. Physical activity is important to the development of bone, muscular strength, and heart and lung health. It helps young people avoid obesity, heart disease, cancers and diabetes (糖尿病) . There is growing evidence that it helps cognitive (认知的) development.

“This is not the good start in life that we would want for our children and adolescents,” said Bull.“The data are worrying for all-parents, the community and the health system.”

Although schools provide sports, they are often under pressure. But Bull said communities and sporting associations can help, and towns can be better planned to encourage active living. Parental encouragement and providing a role model is also valuable.

Besides, a culture change is required, according to the WHO global action plan on physical activity, because there are disadvantages and unintended consequences to the use of digital media. It involves excessive (过度的) amounts of time spent on phones, laptops and gaming devices. The electronic revolution has fundamentally transformed people’s movement patterns by changing where and how they live, learn, work, play and travel. Gradually and eventually, it isolates people indoors.
