3 . In order to meet growing food production and energy needs in low-and middle-income countries, solar-powered groundwater irrigation (灌溉) is rapidly gaining ground. More than 500,000 solar pumps (泵) have been set up in south Asia over the last few years and a major expansion is planned across sub-Saharan Africa.
Dustin Garrick, professor in the School of Environment, Resources and Sustainability, along with an international team, examined the trend toward solar pumps as a clear opportunity for boosting agricultural yields and reducing poverty, but the opportunity comes with risks.
While replacing electric or gas pumps with solar-powered irrigation holds the promise of reducing carbon emissions (排放), it is not guaranteed. Farmers who have access to these pumps may expand production of crops or diversify into other activities, which are not emissions neutral. Solar pumps will increase groundwater pumping efficiency, which may be desirable in regions that support such increases, but this could worsen groundwater lessening in regions that are already stressed. The cheap clean energy of solar pumps may lead to increased groundwater development, without necessarily decreasing overall emissions.
Despite these challenges, the clean-energy boost can serve as a stimulus for positive change in water and energy management but will require enhanced regulation and planning in both low-and high-income settings. Garrick and his team advocate for improved data collection initiatives, with a shift from separated to integrated approaches. They suggest using technology to measure water pumping and collecting remotely sensed data to monitor land use changes. As well, regulatory improvements are crucial, with mounting limits for carbon emissions and groundwater lessening established at various levels.
With groundwater management already a difficult challenge, we must act fast to understand the implications of the clean energy boost and poverty reduction acts to avoid these gains being won away by wells running dry. The rapid adoption of solar irrigation intensifies the urgency, demanding adaptation from governments and institutions to sail through these complexities.

4 . A study published in the journal Nature lists some hybrid (杂种的) species that could become prevalent (盛行的) in the ocean due to climate change. Here are four of those hybrid species.
“Brolar” bears — Brown bears and polar bears
Evidence of a hybrid species born from brown bears and polar bears has been found in the United States and Canada in the past.
Known as “Polar bears” or “Pizzlies”, they have a mostly white coat, with a brownish hue and a nose that is a cross between a polar bear and a brown or grizzly bear.
They are known to be more suited to warmer temperatures than their Arctic relative, as they do not rely so heavily on sea ice for hunting.
“Narlugas” — Narwhals (独角鲸) and beluga whales (白鲸)
In 1990, a hunter in West Greenland discovered an interesting skull, which appeared to be that of a beluga whale-narwhal hybrid. It wasn’t until 2019 that DNA analysis confirmed that the creature was indeed 54% beluga from its father, and 46% narwhal from its mother.
Experts believe that the hybrid may have been grey in color and possessed a tail like a narwhal but forward flippers like those of a beluga whale.
Hybrids of harp seals and hooded seals Numerous species of Arctic seal are expected to mate (交配) to form hybrid offspring due to diminishing sea ice. This includes a hybrid of the harp seal and hooded seal, which both breed on pack ice of the North Atlantic Ocean and extend into the Arctic Ocean in summer months.
A hybrid animal, found in the Gulf of St. Lawrence in Canada, was formally reported and confirmed by molecular analysis in 1997.
“Harbor-Dall” porpoise (鼠海豚) — Harbor porpoises and Dall’s porpoises
Hybrids of the harbor porpoises and the Dall’s porpoises have been found off the coast of British Columbia, Canada. Harbor porpoises are thought to be in decline due to habitat disturbance, meaning they may turn to other species to mate with.
Experts believe more harbor porpoises will move north as temperatures rise, which will further increase their chances of breeding with Dall’s porpoises.

5 . After a decade of negotiations, nearly 200 countries have agreed to a new United Nations treaty(条约)to protect the world’s oceans, the first of its kind in 40 years. The High Seas Treaty aims to protect 30% of the open oceans by 2030, setting a plan in motion to preserve this vast area.
Oceans cover about 71% of the Earth’s surface and are home to countless species of animals and plants. They play a crucial role in maintaining a healthy planet. However, overfishing and pollution from ships and other sources have severely impinged on many marine (海洋的)species and ecosystems.
The last major UN sea treaty in 1982 described the “high seas” — the parts of the oceans that aren’t controlled by any country — but it did not protect them. The high seas, which account for two-thirds of the ocean, currently have only 1.2% of their massive area protected. A marine protected area(MPA)is an area in the sea with strict rules about fishing and other activities. While more and more countries have established MPAs in their waters, most are not connected, limiting their effectiveness for migratory(迁徙的)species.
Last December, over 110 countries committed to protecting 30% of their land and ocean areas by 2030．The High Seas Treaty now enables the extension of this goal to the entire ocean. It aims to make 30% of the high seas become protected areas by 2030 and requires that proposed activities on the high seas undergo assessment for their potential impact on the ocean environment.
Reaching the agreement was challenging due to differing views on ocean protection among countries, such as limits on fishing or pollution. Disagreements also arose over sharing resources between rich and poor nations, with the latter seeking an assurance that resources benefit everyone, not just those in wealthy countries.
The treaty is not yet final and must be officially accepted at a UN meeting. Then it must be approved and signed by enough countries before it takes effect.

9 . Family Vacations in Hawaii
Whether your interests are history, native cultures, hiking, water sports, or simply relaxing in the sun, Hawaii has abundant choices to keep you and your family entertained.
Waikiki BeachThis famous two-mile stretch of sand is home to scores of family-friendly beach hotels and all kinds of action-packed excitement. Waikiki Beach is the perfect place to go if you’re looking for warm ocean water and golden beaches. Kids will enjoy walking along the beach, stopping for shaved ice or an ice cream and taking a dip in a safe area of the ocean.
Oahu’s North ShoreSome of the tallest ocean waves in the world are found at Oahu, Hawaii’s North Shore coastline during the winter months. These crashing walls of water are born for surfing and offer one of the best free shows on the islands. The North Shore is home to world-class surf contests, attracting the world’s top surfers.
Polynesian Cultural CenterNothing appeals to the whole family like Hawaiian past coming alive. Besides, the colorful costumes, lively songs, and traditional dances in the Pacific region are presented here. You’ll see customs of Fiji, New Zealand, Marquesas, Samoa, Tahiti, Tonga, and Hawaii all represented in Polynesian Cultural Center’s re-created island villages, which is decorated with palm trees and tropical gardens.
Waimea Canyon (峡谷) State ParkMore than 3,500 feet deep, this landmark on Hawaii’s island of Kauai is the largest canyon in the Pacific. Unlike Grand Canyon, plentiful rain keeps Waimea Canyon and its surrounding area thick with vegetation (植被), and visitors are frequently treated to the sight of vivid rainbows.

10 . Bees are responsible for one in every three bites of food: from almonds (杏仁) to berries and the alfalfa (苜蓿) that feeds dairy cows. Our diets and agricultural economy hinge on a healthy bee population.
However, rapid declines in bee population around the world put additional stress on an already unstable food supply by depressing yields and agricultural efficiency. While bee biologists do not foresee upcoming food system collapse without honey bees, we do know that agriculture would quickly become unrecognizable—and much more limited.
Farmers are on the frontlines of the economic impacts of bee decline. For example, the cost of almond pollination (授粉) has nearly tripled since colonies began collapsing in 2004, costing that industry over $83 million per year.
The causes behind recent bee declines are not a “mystery”. Independent scientists now largely agree that bee declines are caused by a combination of several factors, including: poor nutrition, habitat loss and pesticide (杀虫剂) exposure.
In the last several years, pesticides — both alone and in combination with other pesticides — have emerged as a key catalyst (催化剂) behind this disturbing phenomenon, both because of their direct toxicity to bees and their indirect and cascading effects.
Scientists know that individual bees can be acutely poisoned while flying through pesticide-contaminated planter dust in a recently planted corn field. More commonly, they are chronically poisoned at sublethal (亚致死) levels by eating and drinking contaminated pollen, nectar and water over time. Bees are then more likely to get sick.
As an indicator species, honey bees are sounding an alarm that we ignore at our peril. Among their lessons: industrial agriculture has gone off the rails. The pesticide treadmill has kicked into high gear with a class of dangerous systemic pesticides—while regulators were asleep at the switch. So let’s keep the heat on decision makers to take meaningful action.
