Starbucks will eliminate plastic    1    (straw) from its stores worldwide in 2021 to reduce pollution    2    (cause) by plastic, the company says. The coffee retailer (零售商) will gradually reduce using single-use straws    3    its more than 28, 000 locations, cutting out    4    estimated 1 billion straws each year. Customers will instead be given plastic lids designed for use without a straw or with non-plastic straws. “Not using a straw is the     5    (effective) thing we have ever done for the environment,” said Colleen Chapman, vice-president of Starbucks’ global social impact, in a statement. The announcement came just one week after Seattle, Washington — home to Starbucks’ headquarters — became the first major US city    6    (ban) single-use plastic straws in bars and restaurants.

Starbucks’ pushback against plastic has drawn a mixed    7    (react). M. Sanjayan, CEO of Conservation International, issued a statement saying “500m plastic straws    8    (throw) away every day in the US” and praised Starbucks for its “meaningful action to protect our oceans” . But many consumers    9    (voice) concern for disabled people. “What about those    10    rely on straws due to disability? I often can’t drink or eat without them.” a customer tweeted.

3 . On a sunny afternoon, Andreas Fath climbed out of a river in Paducah. A small crowd was on hand to witness his setting a new world record. This man had just finished swimming the entire length of the Tennessee River—1,049 kilometers. And he did it in just 34 days!

As a chemist from Hochshule Furtwangen University, the 52-year-old man had taken on this swim for science. His primary goal was not to get his name into Guinness World Records. What really drove this swim was a desire to make people aware of the seriousness of water pollution.

Fath’s crew included his family. Martin Knoll, who helped organize Fath’s swim, also took par t. Knoll is an environmental scientist at the University of the South. He describes this swim as a vehicle for getting people interested in water quality and how we pollute water without realizing it.

It took Fath 34 days to swim the river’s length. Along the way, his crew took measurements of the water’s temperature and pH. They also recorded weather and the speed of the river’s currents (涌流). As for the Tennessee River, they collected daily water samples. A small plastic device attached to one leg of Fath’s wet suit sampled the chemical pollutants (污染物) through which he swam. Finally, Fath’s goal is to use such data to know what on earth results in water pollution. Then he wants to find ways to keep those chemicals out of the water.

Back in Germany, Fath and his students have finished examining their data. They plan to publish their findings soon. Identifying materials that hide in the river isn’t only important for the animals that live there. “It’s also a way to protect human health,” says Fath.

Scientists have exposed that around two-fifths of the world’s plants are at risk of extinction. A top botanist, Professor Alexandre Antonelli, said, “We are living in    1    age of extinction.”

It's a very    2     (worry) picture of risk and urgent need for action. We’re losing the race against time as species are disappearing faster    3    we can find and name them. Many of them could hold important clues for solving some of the most pressing    4     (challenge) of medicine and even perhaps of the emerging and current pandemics we are seeing today.”

There    5     (be) positive signs in the past few years. More than 4, 000 species of plants and fungi (菌类)     6     (discover) in 2019, among which are potential future foods that could be a lifeline to millions of people on Earth suffering from    7     (poor) and food insecurity. Professor Antonelli stressed    8     (firm) the importance of protecting these and all plant life on Earth. He said, “We would not be able    9     (survive) without plants and fungi — all life depends on them. Every time we lose a species, we lose an opportunity     10    humankind.” Leading scientists will demand that the world leaders act against biodiversity loss.

9 . For 30 years we have been told how temperatures have been rising rapidly to unheard of levels. This is causing polar ice to melt, sea-levels to rise and has brought about a dangerous increase in extreme weather events. These intense climatic changes would likely present challenges to our society and environment.

The causes of climate change are mainly anthropogenic (人为的) in nature. Since the industrial revolution, human activities have increased the amount of greenhouse gases in the atmosphere. The increased amount of gases which absorb heat has led to more heat being kept in the atmosphere, causing global warming.

The certainty of global warming can be seen through some of the natural phenomena like the effect on crops and extreme weather conditions around the world. The most recent assessment report says that the earth’s average temperature has risen by 0. 74 degrees in the period from 1906 to 2005, and that the average temperature will continue to rise. There have also been more violent downpours, sea levels have risen and the ice at the world’s poles and on its mountains is melting. The rising sea level is flooding the low-lying countries in Asia and small islands in the Pacific. This may lead to the displacement of millions of people, loss of millions of land and consequently billions of dollars.

Troubled by the serious situation, world leaders came together for the 2015 United Nations (UN) Climate Change Conference in Paris. The climate talks led to 196 countries reaching a landmark agreement that will, for the first time, commit nearly every country to lowering planet-warming greenhouse gas emissions to address global climate change. That was certainly an encouraging step forward for our earth and mankind!

As the world leaders continue to commit themselves to monitor our sick planet, we need to continue to take small steps to heal the world. We are left with not much of a choice. If only we could just pack our bags and migrate to Mars!

10 . The convenience plastic offers has led to a throw-away culture that reveals the material’s dark side. Many of its products, such as plastic bags and food wrappers, have a service life of mere minutes to hours.     1    

Plastic has been the biggest threat to ocean life for decades. Sunlight, wind and wave action break down plastic waste to a certain extent, but it only succeeds in reducing it to smaller pieces.

    2    They spread throughout the water and have been found in every corner of the globe, affecting nearly 700 species, including endangered ones.

    3    They range from birds to fish and to other marine animals. Most of the deaths to them are caused by starvation. Small pieces of plastic have been found in more than 100 marine species, including fish, shrimp, and some seashells. In many cases, these tiny bits pass through their stomachs.     4    Stomachs so packed with plastic reduce the urge to eat, making them die eventually.

Tests have also confirmed cell damage and trouble with animals’ reproductive systems caused by plastic-eating. Some species, such as oysters, produce fewer eggs if they wrongly take too much plastic.

Fortunately, solutions are being found. Many scientists agree the top priority is to prevent plastic waste from entering rivers and seas.     5    Better product design also should be taken into account, as well as the reduction in producing unnecessary single-use plastic products.
