6 . Shop Sustainably

If you have to name one thing that contributes most to your ecological footprints, you may say the energy you use at home, or your car’s emissions.     1     Knowing this can make your grocery shops more planet-friendly. Here is what you can do to help shop sustainably.

●    2     Using those is a great first step. If you get some, do remember to fill them with your purchases. When you adapt yourself to reusing them, then you’ll cut your consumption of single-use plastic bags even further.

●Avoid unnecessary packing. Buy loose fruit and vegetables instead of pre-packaged produce, and avoid products that contain multiple single packages or double packaging, like grain in a box and a bag. Consider switching from tea bags and coffee pods to tea leaves and ground coffee.     3    

●Go organic when you can. In addition to the benefit organic farming has to insect biodiversity, it’s also considered more sustainable and better for the environment.     4    Choosing free-range or Marine Stewardship Council-certified products also encourages environment- and animal-friendly food production.

●Buy seasonal and native products.     5     So you can avoid buying goods that have travelled long distances to reach your plate. As well as opting for local goods, depending on where you live, in the supermarket, you can also buy directly from the source at farmers’ markets.

In downtown Xiamen, Fujian Province, a 6-meter-high mound(土堆) that stretches for 60 to 70 meters stands in contrast to the high-rise     1    (construction) all around. It is a vital place for the blue-tailed bee-eaters. Now they are under second-level state     2     (protect).

The blue-tailed bee-eater, or Merops philippinus, is known for its colorful plumage and on the Chinese mainland it     3     (find) in coastal provinces, such as Fujian and Hainan.

    4    (establish) in 2011 as Xiamen’s inaugural city-level nature reserve in an urban area, the Wuyuanwan Nature Reserve provides     5     crucial habitat for the species.

In recent years, with improved environmental conditions in Xiamen and the city government’s commitment    6     nature conservation, the blue-tailed bee-eaters have become regular visitors.

In 2015, the center     7     (observe) some 70 to 80 birds in the area while in 2023, over 200 of the birds were watched at the nesting site.

The birds,     8     are sensitive to smell, build a new nest every year. Therefore, the mound must be cleared and refilled after the blue-tailed bee-eaters fly south.

    9     (safeguard) their habitat better, the city government issued a notice in 2017, setting up a protective zone around the nesting site, where noise and pollution-producing industries are prohibited     10     (strict).

The 13-year experience of preserving blue-tailed bee-eaters has given the center a grasp of their habits and made the Wuyuanwan Nature Reserve a stable home for them.

9 . How to limit your environmental impact while travelling

Travelling unlocks a world of endless possibilities and adventures, allowing us to hike through breathtaking landscapes, encounter kangaroos and deer in their natural habitat, and witness the power of volcanoes.     1     Increased plastic waste and noise pollution can damage ecosystems. Thankfully, there are ways to limit our impact on the environment.

Try to travel by land instead of air. While air travel can often be quicker, it is typically one of the most polluting forms of transport.     2     For example, if you’re heading to Las Vegas from Los Angeles, driving for around four hours emits (排放) around 75% less CO₂ compared to the one-hour flight (provided you have several friends with you).

    3     A typical hotel uses about 73,000 gallons of water per year. As laundering towels (洗熨毛巾) is an energy-and-water-consuming process, many hotels often put up signs asking you to re-use your towels. By doing so, you’ll reduce your environmental impact.

Make the most of safe tap water (自来水). Drinking tap water may come as a shock to many travelers. But when you’re in countries where tap water is safe to consume, avoid bottled options. Not only are they more expensive, but they have a higher level of pollution compared to treated tap water.     4    

Respect the local environment. When visiting different destinations, we should recognize the importance of protecting the natural beauty. We mustn’t throw rubbish everywhere.     5     Additionally, supporting local conservation (保护) efforts, such as participating in community-led clean-up projects, can make a positive impact on the local environment.

10 . Like many of the Indigenous (土著的) communities across the Australian continent, the remote communities in north-west New South Wales are struggling. Many of the 300 or so residents rely on welfare. Higher electricity bills—up to $3,000 a quarter for some households—further worsen the poverty. They’re always at the end of the power line, so the service that is there is quite extraordinary in terms of cost. It’s a real problem that needs to be fixed.

To that end, Anderson and other Indigenous leaders have formed the First Nations Renewable Energy Alliance (FREA) to push for renewable energy in Indigenous communities. They partner with private enterprise to support Indigenous communities looking to switch to renewable energy.

“We can build a power station where the community exists,” Anderson says, “so people are able to successfully live in the environment the way they want to live and have access to power which enables them to better determine their economic future.”

Only a handful of Indigenous communities have set up renewable energy projects in Australia. The Indigenous-owned and -operated company AllGrid Energy, for instance, has installed solar panels and battery storage systems to replace diesel (柴油) generators in the communities of Ngurrara and Kurnturlpara in the Northern Territory’s Barkly Tableland. Within two months of the system being installed in May 2016, people were moving back to their homelands, the communities growing from just two permanent residents to about 40.

But FREA will go one step further, working with community leaders and acting as a conduit (纽带) between the communities and the businesses they are dealing with. This is essential, says Anderson, to avoid predatory (吞并) practices they have seen in the past, with companies “playing on the psychology of poverty” to gain advantage. The FREA has drafted terms of agreements that will guide how companies engage with Indigenous communities for renewable energy projects.

One of the next steps for FREA will be to identify a community that can act as a test case for a renewables project. “Our experience is that if we can make it work for one community, it will work in every other community,” Anderson says.
