Return of delicate aquatic plant signals Chinese lake's revival_我的网站
A | CANBERRA, Australia -- Ultramarathon runner Pat Farmer ended a 14,400-kilometer (8,950-mile) run at the central Australian sandstone landmark Uluru on Wednesday after a seven-month journey to raise public support for the creation of an Indigenous advocacy body in the constitution.Australians will vote on Saturday at a referendum that would enshrine in the constitution a so-called Indigenous Voice to Parliament, a mechanism for Indigenous Australians to advise lawmakers on policies that effect their lives.Prime Minister Anthony Albanese was at Uluru, which is an Indigenous sacred site also known as Ayers Rock, to welcome the 61-year-old runner’s arrival.Albanese said he had “utter admiration and awe” for Farmer’s commitment for the cause which opinion polls suggest is unlikely to succeed.“No one has done more than this bloke and I am very pleased to welcome him here at Uluru,” Albanese said.Farmer said his first glimpse of the enormous rock rising from the flat Australian wilderness at a distance of 40 kilometers (25 miles) brought a tear to his eye.“I’m glad. Very, very happy to be at this point in time, this point in the world’s time where we start to acknowledge Indigenous communities right around the world and the significance of that culture,” Farmer told reporters.The former lawmaker's run began in Hobart on the island state of Tasmania on April 17 and traversed every Australian state as well as both mainland territories.Uluru has special significance in the campaign to create the Voice as a means of acknowledging Indigenous Australians in the constitution.The Voice was recommended in 2017 by a group of 250 Indigenous leaders who met at Uluru. They were delegates of the First Nations National Constitutional Convention the then-government had asked for advice on how the Indigenous population could be acknowledged in the constitution.Indigenous senator Pat Dodson, the government’s envoy for promoting the Voice, joined the referendum campaign on Wednesday for the first since taking medical leave in April for treatment of non-Hodgkin lymphoma.He said in a National Press Club speech he remained confident that a majority of Australians would vote for the Voice despite polls showing its popularity had slid in recent months.A “No” decision would be a backward step for Australia after the High Court ruled in 1992 that Indigenous Australians had land rights that predated British colonization and after the Australian Parliament apologized to the Indigenous population in 2008 for past injustices, Dodson said.“Do you want to go forward or do you want to go backwards or do you want to do nothing? Do you want to look yourself in the mirror and have pride the next day, or have some doubts and uncertainties and even an increase in shame? ” Dodson asked voters.While recent opinion polls suggest most Australians oppose the Voice, a poll published Wednesday found 59% of Indigenous respondents were in favor.That support had slipped from more than 80% supported suggested by polls published early this year.The latest poll published in The Sydney Morning Herald newspaper was based on an online survey of 420 Indigenous voters between Sept. 22 and Oct. 4. It has a 4.8 percentage point margin of error.Indigenous Australians account for 3.8% of Australia’s population. They have worse outcomes on average than other Australians in a range of measures including health, employment, education, incarceration and suicide rates. Statistically, Indigenous Australians die around eight years younger than the wider community.。

The delicate blossom seen floating there is Ottelia acuminata, an aquatic plant endemic to China, which is known to have extremely strict water quality requirements. It demands high water transparency, cleanliness and calcium content, and survives only in unpolluted waters, serving as a reliable natural indicator of aquatic ecological health.
Its large-scale revival vividly testifies to Erhai Lake's remarkable ecological restoration achievements.
China's Ecological and Environmental Code, enacted on Saturday, stipulates nationwide protection and restoration of river and lake ecosystems, providing solid legal support for systematic water ecological governance across the country.
As China advances its Beautiful China initiative, this code is expected to strengthen rule-of-law guarantees for ecological protection and provide fresh impetus for the country's green and low-carbon transition.
In the early 1990s, agricultural pollution worsened Erhai Lake's water quality, causing frequent blue-green algae outbreaks. A severe algae bloom hit the lake in 1996, leaving the water turbid and smelly. As the environment degraded, Ottelia acuminata nearly disappeared from the lake.
Thanks to years of targeted ecological protection and restoration efforts, the lake's water quality has improved steadily, maintaining an excellent Grade II standard from January to June 2026, and creating favorable conditions for the return of Ottelia acuminata.
Official data show that the plant's coverage on Erhai Lake has surged from 90,000 square meters in 2021 to 950,000 square meters in 2026, marking a remarkable ecological recovery.
The improved water environment has also brought tangible economic benefits, turning the lake's ecological advantages into a sustainable industry. From lake ecology to farm cultivation and consumer products, Ottelia acuminata's dual ecological and economic value has been fully realized.
In 2018, environmental worker Zhong Lan noticed the edible plant's great potential for water purification and industrial development. With support from local authorities and Shanghai Jiao Tong University in eastern China, she started a company and built a professional research base in 2024, developing standardized planting techniques that enable high-yield, repeated harvests and offering jobs for local villagers.
Villager Li Xinyuan, who quit Ottelia acuminata cultivation years ago due to low profits, resumed planting in 2023 and earns a stable monthly salary of 4,500 yuan (about 663 U.S. dollars) at the base.
His fellow villager Du Hongquan earned over 100,000 yuan last year from growing the plant and has more than doubled his planting area this year. "The base takes full charge of sales, so we can plant without any worries," Du said.
Eryuan County, the source of Erhai Lake, now has more than 200 hectares of Ottelia acuminata plantation area, creating numerous jobs yearly. The plant has been developed into a diverse range of products like tea, plant-based coffee and cookies.
"I used to think it was exclusive to Yunnan, but I can try it elsewhere too," said a tourist surnamed Ai after tasting the plant at a hotpot restaurant in Hangzhou, east China's Zhejiang Province.
The beautiful lakeside scenery at Erhai has also boosted local tourism. In 2025, Dali received over 120 million tourist visits, attracting visitors to enjoy lake views and experience local Bai ethnic culture, with 407,000 long-term visitors.
Last month, the State Council issued a plan for building a Beautiful China during the 15th Five-Year Plan period (2026-2030), setting out the overall requirements, targets, key tasks and major projects for comprehensively advancing this initiative.
According to the plan, China will achieve overall improvement in ecological and environmental quality and make significant progress toward building a Beautiful China by 2030, with green production and lifestyles largely established and the carbon peaking target reached on schedule.
