2 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf causes serious water shortage in some local areas.

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment   and buying products made from recycled materials. But the final goal should be “green gyms”. They   are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces.

There is no special requirement for you to start your membership. And best of all, it’s free.

3 . Tips for Green Travel with Kids

Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.     1    

It’s easy when travelling to pull in to fast food restaurants for snacks.     2     My kids love to help plan snacks. I let them create their own snacks for the trip at home.

    3     At the airport, keep your reusable bottles empty until you have passed through the security (机场安检区). Fill them up on the other side of the security checkpoint. Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4     In addition, opening a few windows and turning off the air conditioner (空调) are also good ways to save energy. You should also help your children keep their good, green habits while travelling. Sometimes vacation can mean more than one shower each day-once in the morning and again after getting out of the pool. Pay attention to the number of showers (淋浴) and the length of showers.     5    

5 . Worried about the climate?    1    . Here are some examples to get you started.

•Count the birds and the bees

Get closer to nature by becoming a citizen scientist. You could be counting birds in your garden, butterflies, insects and flowers, or even reptiles and hedgehogs.    2    . It’s a fun group activity, and your data can help scientists better understand the impact of human behaviour on natural habitats.

•    3    

Media headlines can be alarming when it comes to the climate and nature crisis or ignoring the issues completely. Hosting a local discussion can allow space for reflection, debate, ideas and collaboration (合作) to take action on global issues at a local level.

•Set up a library of things

Internet shopping has made it too easy to buy new stuff at the click of a button.    4    ? First, it’ll clutter (凌乱地塞满) your house，then it’ll clutter the planet. Setting up a library of things can encourage local people to share everything from tools to instruments, cooking gadgets to toys.

•Start a climate emergency centre

    5    . That’s why more and more climate emergency centres are popping up in derelict (废弃地) shops on high streets and in shopping centres. A climate emergency centre can be a space for events such as an exhibition on plastic waste or a workshop to learn how to make eco-cleaning products. It can also be a way to motivate more people to take action.

6 . A Plastic Ocean is a film to make you think.Think,and then act.We need to take action on our dependence on plastic.We’ve been producing plastic in huge quantities.Drinking bottles,shopping bags and even clothes are made with plastic.    1     What happens to all the rest?This is the question the film A Plastic Ocean answers.

The film begins as a journey to film the largest animal on the planet,the blue whale.But during the journey the filmmakers make the shocking discovery of a huge,thick layer of plastic floating in the Indian Ocean.    2     In total,they visited 20 locations around the world during the four years to make the film.

In the film there are beautiful shots of the seas and marine life.    3     We see how marine species are being killed by all the plastic we are dumping in the ocean.The message about our use of plastic is painfully obvious.

    4     In the second half,the filmmakers look at what we can do to deal with the problem.

They present short-term and long-term solutions.These include avoiding plastic containers and recycling as much as you can.The filmmakers also stress the need for governments to work more on recycling programmes.

We make a shocking amount of plastic.Over 300 million tons of plastic are produced every year,and at least 8 million of those are dumped into the oceans.The results are disastrous,but it isn’t too late to change.    5    

7 . Should We Create More National Parks to Save Endangered Animals?

Don’t you find it worrying that more and more species of animals are in real danger of becoming extinct?     1     And I think the best way to do this is for governments to create more national parks.

    2     If this environment is destroyed — for example, when farmers clear a forest for new fields, or trees are cut down to make profits — many animals are unable to survive, and more species are likely to become extinct.

On the other hand, some people fight against the creation of national parks because they consider it is wrong to interfere with nature. They believe that wild animals are happier living in their natural environment.     4     They also point out that a few species are more likely to produce young animals in the wild than in national parks.

All in all, these disadvantages are far less important than the benefits of national parks.     5     As a matter of fact, they protect animals from their greatest enemies, that is, human beings.

9 . New bio-plastics are being made in laboratories from straw, wood chips and food waste, with researchers aiming to replace oil as the source of the world’s plastic.

The new approaches include genetically modifying bacteria to eat wood and produce useful chemicals. But the bio-plastics are currently significantly more expensive to make than fossil fuel-based plastics.

Land and seas around the world, from high mountains to deep oceans, have become polluted with plastic, prompting major public concern. The world has produced 8bn tons of plastic since the 1950s and demand is still rising.

While some waste plastic is recycled, much of it is burnt to produce electricity, resulting in carbon emissions that drive climate change. In contrast to plastic made from oil, plastics made from plant-based materials only release the carbon the plants absorbed from the air as they grew. Bio-plastics will also give more options for products that biodegrade (生物降解) in the environment, although they can be made very long-lasting if required.

“Plastics are an incredible enhancement to our daily lives,” said Paul Mines, CEO of Biome Technologies in the UK, which has spent t5m in the last five years on bio-plastics research. “But we can’t go on using fossil fuel-based materials. About 6-7% of every barrel (桶) of oil is used to make plastics.”

“Using plant materials is feasible,” said professor Simon, at the University of York. “Replacing half of the nation’s plastic bottles could be done using just 3% of the sugar beet crop, 5% of wheat straw or 2.5% of food waste,” he said.

Currently, just a few thousand tons of bio-plastic are used in the UK each year, compared to millions of tons of conventional plastic. Mines said this could rise to about 20,000 tons in the next five years.

10 . Notpla, a London-based firm, makes a seaweed-based substitute (代替物) for single use plastic packaging. Although some of Notpla’s products are suitable to be eaten, they are designed to be dissolved (溶解) after usage. Made of seaweed instead of a conventional plastic coating, the company’s packaging is fully biodegradable and ideal for use as packaging for kitchen and bathroom supplies like coffee and toilet paper.

According to the United Nations, 331 million kilograms of plastic garbage is produced annually around the world. About 60% of the estimated 9.15 billion tons of plastic produced since the early 1950s has been taken to landfills.

Plastics harm the water, the air, and our bodies. Many experts agree that single-use plastics are unnecessary and dangerous. Some governments and towns in the United States have taken action. New York has banned most plastic shopping bags, while plastic straws have been banned in Miami Beach. Overseas, India stated in August that it plans to place a wide ban on single-use plastics this upcoming summer, with the European Union already implementing this ban.

Seaweed comes in a variety of species and can be harvested or farmed. Notpla uses plants that have been farmed. Rodrigo Garcia Gonzalez and Pierre Paslie, the inventors of Notpla, initially considered seaweed as a solution to the world’s plastic problem for several reasons. Seaweed is plentiful and grows quickly. Additionally it doesn’t compete with land crops and is highly favored for its ability to remove some waste products like carbon from the atmosphere.

In cooperation with the online food ordering service Just Eat, the startup recently tested its product. Last year, the two companies handed out 30, 000 takeaway boxes at various UK restaurants. Plans are in the works to offer the boxes across Europe in 2022. Notpla’s team intends to replace single use plastic in the supply chain more generally as they scale. The company recognizes the difficulty of such a job, considering the volume of plastics consumed around the world.
