Right now， most people's attention is on the COVID﹣19 pandemic. In     1    way， this pandemic is also warning us to protect our planet Earth.

World Earth Day， the international movement aiming     2    protecting and improving Earth's environment， is celebrating its 50th anniversary on April 22. For Earth Day 2020， the theme is climate action.    3    （celebrate） this， the Earth Day Network organized the Great Global Clean﹣up event. The network hoped that this would be the largest volunteer event in history， with people from all over the world    4    （set） up events to remove billions of pieces of trash from green spaces， urban communities and waterways. But due to the current ban on public gatherings and lockdown measures in many affected countries， clean﹣up events     5    （postpone）.

That said， the occasion will still continue in a digital way. "    6    it be coronavirus or our global climate crisis， we cannot shut down.    7    ， we must shift our energies and efforts to new ways to mobilize （动员） the world to action. " said Earth Day Network President Kathleen Rogers.

While the event may not reach its originally     8    （plan） grandeur（宏大）， Earth Day 2020 could play a role in helping us sustain     9    （environment） friendly changes， such as practices like teleworking and video conferencing     10    have become more prevalent （普遍的） in this time.

2 . Clothing rental is a hot new industry and retailers (零售商) are demanding to get on board in hopes of attracting green shopper.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated (调查) this question and concluded that it's not as sustainable as it seems.

Take shipping, for example, which has to go two ways if an item is rented — receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.

She writes, ''An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.''

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene (氯乙烯), a carcinogenic (致癌的) air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.

Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it's so easily accessible. There's something called ''share washing'' that makes people waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as ''a way to share rides and limit ear ownership.'' and yet ''it has been proven to discourage walking,bicycling, and public transportation use.''

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step — that's wearing what is already in the closet.

6 . Skeptics are strange a lot. Some of them refuse to admit the serious threat of human activities to the environment and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The "eco-guilt" brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.

Perhaps that explains why a new book by Bjorn Lomborg received so much publicity. That book, The Skeptical Environmentalist, declares that it measures the "real state of the world" as fine. Of course, another explanation is the deep pockets of some big businesses with special interests. Indeed, Mr. Lomborg's views are similar to those of some industry-funded organizations, which start huge activities through the media to confuse the public about issues like global warming.

So it was strange to see Mr. Lomborg's book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that "After Lomborg, the environmental movement will begin to die down."

Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg's "preference for unexamined materials is incredible".

A critical eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interest. People might become half-blind before a world partially exhibited by the media. That's a shame, because matters concerning the health of the planet are far too important to be treated lightly.

8 . “The fact that the smoke reached São Paulo and blackened an afternoon proves how unusual the fires that burn in the countryside of Brazil are,” Ricardo Mello, head of the World Wide Fund for Nature's (WWF) Amazon program, said.

The latest figures come at a time of international protest against the inaction of President Jair Bolsonaro's administration. In July, Brazil's National Institute for Space Research (INPE) showed data to the public, which indicated that there had been a significant rise in deforestation (毁林) rates. Particularly, the figures showed that in July 2019, deforestation had increased nearly 300 percent in comparison to the same month in 2018.

Environmentalists are becoming increasingly concerned, accusing the government of encouraging deforestation and those who want to make use of the forest for commercial gain. During his time in power, Bolsonaro has moved to rob some power of government agencies that are responsible for protecting the rainforest as well as regulations covering native lands and nature reserves. Bolsonaro sees these kinds of regulations as a drag on economic growth in the Amazon region.

Fire in the Amazon is used as a technique to clear land for agriculture. “Farmers clear cut land to make way for agriculture, and then wait for the dry season to set fire to clear the land so they can plant，” Mello said. “It's likely that all of these forest fires are deliberately set by humans.”

Now it is the dry season in the Amazon, which means conditions in many parts of the rainforest are suitable for the fires to spread over large areas. “It is very unlikely that those fires break out naturally，” Mello said. “It is important to remember that 2019 is not a strong El Niño year. When we have strong El Niños, weather gets drier in the northern part of Brazil and this favors fires. This is not the case of 2019.”

9 . We need to be responsible for our environment. Being a frugal consumer (节俭的消费者) is one way to help.     1    

You can use things up instead of wasting them. Squeeze (挤) that last bit of toothpaste out of the tube.     2     Don’t throw away any bits of the biscuit at the bottom of the box.

You do not always need to have new things. Suppose your sneakers (运动鞋) have broken laces (鞋带) , but they still fit you. Repair them and wear them longer. You don’t have to have the latest iPhone until the old one doesn’t work any more. Then you can get a new one.     3    

When something you want is not on hand, look for something else that you already have to take its place. Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so you can use all of the cheese. Learn to fix broken toys instead of just throwing them away.     4    

    5    

Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up our world’s resources (资源). And, getting rid of the things we don’t want any more takes up even more resources and space.
