3 . We Need to Think about Conservation on a Different Timescale
Time, perceived by humans in days, months, and years, contrasts with nature’s grander scales of centuries and millennia, referred to as “deep time.” While paleontologists (古生物学者) are trained to think in deep time, conservationists are realizing the challenges it poses. Shortsightedness about time limits modern conservation, with efforts often overlooking past healthy conditions of ecosystems in the context of climate and biodiversity crises.
The shifting baseline syndrome (综合症), where standards in a place change gradually, makes conservation more complex. It involves evaluating ecosystems primarily on their recent past, often with negative consequences.
Recent shifts in California’s forest management practices, from stopping fires to embracing Indigenous knowledge of controlled burns, exemplify the importance of understanding historical ecosystem dynamics. To enhance conservation, adopting a deep-time approach is crucial.
Modern mathematical modeling, combined with long-term data, offers a pathway for preserving ecosystems. In California’s kelp (海带、海藻) forest, researchers identified an overlooked keystone species — the extinct Seller’s Sea Cow (大海牛). By examining past kelp forests, a deeper story impacting regeneration was revealed. The sea cow, a massive plant-cater, contributed to a diverse, vital undergrowth by trimming kelp and letting light reach the area.
The researchers put forward a novel approach to kelp forest restoration: selectively harvesting kelp, imitating the sea cow’s impact. This strategy, considering historical dynamics, challenges assumptions about recent ecosystems and offers new conservation methods.
Rather than only focusing on removing urchins (海胆) or reintroducing sea otters, the researchers suggest employing teams of humans to selectively harvest kelp, as the Steller’s sea cow once did, to encourage fresh growth. This sustainable harvest could benefit both the ecosystem and human consumption.
In short, assumptions based on the recent past may impede the understanding and protection of ecosystems. On the other hand, the application of controlled burns, similar modeling studies, and a deep-time perspective (视角) could significantly transform conservation efforts. Recognizing our role in an ongoing narrative spanning millions of years is essential, urging a comprehensive understanding of ecosystems through time. Embracing this role is crucial for shaping the future and establishing vital connections from the past to the future.

4 . The high-tech revolution has inspired a pleasure endless stream of new and exciting electronic products that we just can’t live without. In fact, the speed of technological innovation can make last year’s must-have this year’s junk. And that’s the problem.
The average life span of a personal computer has been shortened to around 18 months and this has nothing to do with worn-mice or damaged disk drives. Simply put, electronic products can become out of date before you’ve even figured out how they work.
So what happens to all those old keyboards, monitors, organizers and CPUs? Most are stored away in a warehouse (仓库), taking up valuable space. But many end up in landfills, and that is where the trouble really begins. Computer monitors can contain up to 3.5 kg of dangerous waste once they are no longer in use.
Unfortunately, this problem is not going to disappear anytime soon. In fact, it is growing by the minute. In Japan alone, people throw away some 20 million TVs, washing machines, refrigerators and air conditioners each year. What is to be done with all this techno-trash?
One way to reduce waste is to avoid throwing away in the first place. Many companies reuse parts from old products in new models. This is not cheating-it makes both environmental and economic sense. Cannon, for example, has adopted a philosophy known as “kyosei”, meaning “living and working together for the common good?” — a goal of achieving balance between the environment and the corporate (公司的) activities. The company has even gone so far as to say that environmental assurance should come before all business activities, and that companies unable to achieve such assurance do not deserve to remain in business.
As part of that effort, the company has started a global recycling program with a goal to reduce, reuse and recycle more than 90% of its used products. In 1999, for example, Cannon collected 128, 000 copying machines and 12, 175 tons of toner cartridges (色粉盒) in Japan, Europe and the United States.
Some argue that electronic garbage can also be controlled during the design phase. This concept, called “design for the environment”. Not only does this make environmental sense, but it saves the customer money. IBM, meanwhile, recently planned programs in Canada and the US that, for a small fee, will take back not just an IBM but also any manufacturer’s computer. Depending on the age and condition, the equipment will then be either donated to charity, or broken down for reusable parts and recyclable materials.

Antarctica is the center of important scientific research. However, with an increasing number of day, scientists have to leave their work to greet a group of tourists who are taking a vacation in this continent of ice. Even though their desire to enjoy this vast and beautiful landscape can be appreciated, Antarctica should be closed to tourists.
Tourists in Antarctica can damage scientific research and hurt the environment. When tourist groups come, they take scientists away from their research. The work is difficult and some of the projects can be damaged by such simple mistakes as opening the wrong door or knocking against a small piece of equipment. In addition, tourists in Antarctica can also hurt the environment. Members of Greenpeace, one of the world’s leading environmental organizations, complain tourists leave trash on beaches and disturb the plants and animals. In a place as frozen as Antarctica, it can take one hundred years for a plant to grow back.
The need to protect Antarctica from tourists becomes even greater when we consider the fact that there is no government here. Antarctica belongs to no country. Who is making sure that the penguins, plants and sea are safe? No one is responsible. It is true that the number of tourists who visit Antarctica each year is smaller compared to the number of those who visit other places. However, these other places are controlled by local governments. They have an interest in protecting their natural environments. Who is concerned about the environment of Antarctica? The scientist, to be sure, but not necessarily the tour companies that make money from sending people south.
If we don’t protect Antarctica from tourism, there may be serious consequences for us all. We might lose the results of scientific research projects. It’s possible that these results could teach us something important about the causes and effects of climate change. Some fragile plants and animals might die and disappear forever. This could damage the balance of animal and plant life in Antarctica. We know from past experience that when things get unbalanced, harmful changes can occur.

9 . Scientists have discovered more than 5,000 new species living on the seabed in an untouched area of the Pacific Ocean that has been identified as a future hotspot for deep-sea mining, according to a review of the environmental surveys carried out in the area.
It is the first time the previously unknown biodiversity of the Clarion-Clipperton Zone (CCZ), a mineral-rich area of the ocean floor that spans 1.7m sq miles between Hawaii and Mexico in the Pacific, has been comprehensively documented. The research will be critical to assessing the risk of extinction of the species, given contracts for deep-sea mining in the near-pristine area appear imminent.
Most of the animals identified by researchers exploring the zone are new to science, and almost all are unique to the region: only six, including a carnivorous sponge and a sea cucumber, have been seen elsewhere.
Contracts for mining exploration in the CCZ have been granted to 17 deep-sea mining contractors in an area covering 745,000 sq miles. The companies, which are backed by countries including Britain, the US and China, want to dig for minerals including cobalt manganese and nickel in part to sell to the alternative energy sector.
To better understand the impact of mining this fragile ecosystem and its newly discovered inhabitants, an international team of scientists has built the first “CCZ checklist” by compiling all the records from expeditions to the region. Published in the journal Current Biology, it includes 5,578 different species, of which an estimated 88% to 92% had never before been seen.
To study and collect specimens (样品) from the ocean floor, biologists have joined research cruises in the Pacific that send remote-controlled vehicles to traverse (穿越) the seabed 4,000 to 6,000 meters below. Adrian Glover, a deep-sea biologist at the NHM and senior author of the study described it as an “incredible privilege”. The expedition, funded through the Natural Environment Research Council and others, is backed by UK Seabed Resources (UKSR), a deep-sea mining company that operates the UK’s exploration area. The scientists watch operations by video link direct from the boat as new species are gathered by remote control vehicles in the darkness below.
The seabed, Glover said, is an “amazing place” where, despite the extreme cold and dark, life thrives. “One of the characteristics of the abyssal plain is the lack of food, but life has a way of persisting down there,” he said, “It’s a mystery.” One of the deep-sea animals discovered was nicknamed the “gummy squirrel”, because of its huge tail and jelly-like appearance, he said. There are also glass sponges, some of which look like vases.
With approval for deep-sea mining looming, Glover said he believed it was “imperative that we work with the companies looking to mine these resources to ensure any such activity is done in a way that limits its impact upon the natural world”.
