1 . “For thousands of years, humans have raced to be the first to climb a peak, cross a frontier, or document a new species or landscape. Now in some cases, we’re racing to be the last,” said New York Times’ Paige McClanahan.

In recent years, a growing industry has been stimulated by climate change — last-chance tourism. According to Eco Sustainable Solutions, a UK-based organic recycling and waste processing company last-chance tourism is a kind of tourism geared toward seeing the last of something due to climate change. As temperatures and water levels rise, this could mean seizing the last chance to see the Great Barrier Reef, an Arctic glacier and a remote island that is sinking.

As millions of tourists rush to imperiled destinations, some are taking advantage of the increasing demand to spread environmental awareness. One tourist spot, the Sea of Ice in France, opened an exhibit in 2021 to educate visitors on glaciers and climate change. This educational push seems to be having an impact, as a 2023 survey showed that 80% of the visitors would try to learn more about the environment and how to protect it while 77% said that they would reduce their water and energy use.

However, the last-chance tourism industry may become kind of our concern. As more and more people flood into these areas in a panic to see them before they are gone, they in fact contribute to the increased greenhouse gas emissions and over tourism, leading to their destruction. Just as many scholars put it, last-chance tourism is a paradox (悖论).

Although tourists may acknowledge the broader risks and importance of climate change, it’s even more important to connect the responsibility of the individual tourism to the future of our planet. It’s not just about understanding the need to stop climate change; it’s even more important to avoid making it worse.

4 . Aviation is a big polluter. Cutting the sector’s impact on global warming is high on the agenda. Although many governments are regulating emissions from cars and trucks, air transportation is technologically rooted in old patterns.

Facing the reality that the sector will keep emitting a lot, ICAO has established an international carbon-trading plan—Carbon Offsetting and Reduction Scheme for International Aviation, or CORSIA. This encourages wide use of offsets (抵消) : aviation companies can buy emissions credits or invest in sectors that store carbon, such as forestry, to allow them to carry on as normal. CORSIA aims to keep CO2 emissions at 2019 levels through such purchases for emissions over that year’s baseline. ICAO predicts that increasing demand might reach 1. 7 billion tons by 2035, potentially making aviation the largest offset market in the world.

Yet offsetting faces a fundamental challenge: the size of the offset requires estimating flows of warming pollution that would have occurred if the carbon-removal project hadn’t existed, and comparing them against flows with the project in place. The former — a baseline that is unobservable — is a hotbed for shady accounting.

The vast majority of offsets today and in the expected future come from forest-protection and regrowth projects. The track record of reliable accounting in these industries is poor, because they lack convincing baselines. Even with oversight, forest projects are often troubled by wild assumptions, for example that trees would disappear completely from these areas in the absence of those projects, even when there are other forest protections in place. Such assumptions drive up baselines and flood the market with huge volumes of offsets. They make it easier for accountants to claim a net reduction in emissions even though the atmosphere sees little or no benefit. These problems are essentially unfixable. Evidence is mounting that offsetting as a strategy for reaching net zero is a dead end.

In our view, this approach could prove dangerously narrow. Removing aviation’s impact on global warming means upending the industry. The longer that reality is overlooked, the harder it will be to find effective solutions.

6 . Birders get nervous when they see landscapes covered in wind turbines (涡轮机). When the wind gets going, their blades (叶片) can turn around at well over 200km per hour. It is easy to imagine careless birds getting cut into pieces and wind turbines do indeed kill at least some birds. But a new analysis of American data suggests the numbers are negligible, and have little impact on bird populations.

Erik Katovich, an economist at the University of Geneva, made use of the Christmas BirdCount, a citizen-science project run by the National Audubon Society. Volunteers count birds they spot over Christmas, and the society gathers the numbers. He assumed, reasonably, that if wind turbines harmed bird populations, the numbers seen in the Christmas Bird Count would drop in places where new turbines had been built. Combining bird population and species maps with the locations and construction dates of all wind turbines, he found building turbines had no noticeable effect on bird populations.

Instead of limiting his analysis to wind power alone, he also examined oil-and-gas extraction (开采), which has boomed in America over the past couple of decades. Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon. When drilling happened in migration centers, feeding grounds or breeding locations, bird numbers instead dropped by 25%.

Wind power, in other words, not only produces far less planet-heating carbon dioxide and methane than do fossil fuels. It appears to be significantly less damaging to wildlife, too. Yet that is not the impression you would get from reading the news. Dr Katovich found 173 stories in major American news media reporting the supposed negative effects that wind turbines had on birds in 2020, compared with only 46 stories discussing the effects of oil-and-gas wells.

7 . People have always believed that nature is good for health and happiness. According to scientific studies, being in nature makes people less stressed. In a recent experiment in Japan, one group of people were asked to walk through a forest while another group had to walk through a busy city.     1    . However, researchers found that after the walks, the people who had walked in the forest had better moods, less anxiety and even lower blood pressure. So the experiment showed that it was being in nature that helped people feel less stressed, not just the walk.

Gregory Bratman from Stanford University in the United States found in experiments that a walk in nature could have important cognitive (认知) benefits, improving a person’s memory and creativity.     2    . Teachers find that when children are enjoying the natural world, their awareness and creativity are improved, along with their reasoning and observational skills.

Why does being in nature bring so many benefits for us?     3    , so we have an instinctive (本能的) love for it. Even just looking out of the window at a beautiful tree can help us feel less stressed.

Scientists also think that being in nature helps our brain recover from a lot of activities that we usually do during the day such as working on math problems or using our cell phone.     4     — putting all our attention into one thing, which can make us feel tired. But when we are outside, we use undirected attention. We see an interesting cloud or a beautiful flower, and our attention moves quickly and easily from one thing to another. So being in nature gives our brains the chance to rest.

    5    . For many of us, nature is something we can enjoy just by walking out of our door. So enjoy the nature around you!

9 . In today’s world, where the consequences of climate change are becoming increasingly evident, the need for energy conservation has never been more pressing.     1    .

Use your laptop more than your desktop

Laptops use an average of 20 to 50 watts of electricity to run, whereas desktop computers use an average of 60 to 200 watts of electricity to run. The reason for this is that laptops run off of battery power and desktops are continuously plugged into a power source that drains energy.

    2    . Not only does this help reduce your energy usage, but it also optimizes your laptop’s battery life to last longer.

Charge your phone in airplane mode and before bedtime

While charging, switch your phone to airplane mode, so that the phone does not slow down the charging process by continually burning energy trying to connect with cell phone towers and plot your location with its GPS function. When you switch to airplane mode your phone charges more quickly.

The brighter the screen setting, the more power it uses and vibration uses more energy than a ringtone.     3    , therefore less energy consumption. And remember-unplug your charger if not in use!

Unplug mobile phone and laptop chargers

Always unplug electronics and appliances when not in use.     4    . When the power strip is left on, the devices plugged into it continue to use energy and actually increase your energy usage. The Northern Resources Defense Council found that devices in sleep or standby mode account for about one- quarter of all residential energy consumption.
