發(fā)布:2024/5/23 20:38:36組卷:3引用:1難度:0.71009.The Kirtland's warbler(鶯)has required protections since the foundation of Endangered Species Act (ESA),but that's about to change.The Fish and Wildlife Service(FWS)today announced it is removing the songbird from the endangered species list.
"The effort to recover the Kirtland's warbler is a successful example of how to save endangered species," said Margaret Everson,director of FWS. "The Kirtland's warbler has responded well to active management over the half century. " In 1971,the Kirtland's warbler population declined to approximately 201 singing males and was restricted to six counties.By 2015,the population reached 2,383 singing males and had spread geographically.FWS noted the frequent and persistent singing of male warblers during the breeding season made counting possible.
"The primary threats identified at listing and during development of the recovery plan have been managed," said FWS.Modern wildfire suppression(撲滅)practices greatly altered the natural disturbance system,which enabled the growth of the jack pine forests favored by the species,F(xiàn)WS noted.Michigan state has replanted approximately 90,000 acres of Kirtland's warbler habitat over the past 30 years.Timber(木材)incomes offset the cost of replanting jack pine needed to support a survivable bird population.
But while the bird is falling off the ESA list,officials note that it remains a "conservation-dependent species." Conservation of the Kirtland's warbler will continue to require a harmonious approach for carrying out future conservation work,like partnerships and sufficient funding,F(xiàn)WS stated.Under the Endangered Species Preservation Act of 1966,the Kirtland's warbler was federally listed as an endangered species in 1967.
"This remarkable bird has a most impressive,exemplary success story that illustrates effective conservation and cooperation at work," added Heather Good,executive director of Michigan Audubon.Shawn Graff,vice president of American Bird Conservancy's Great Lakes program,pointed out the delisting (除名)is "cause for celebration and proof that the Endangered Species Act works."

The ocean is of great importance to life on Earth,but why,exactly,is this the case?Here are some reasons why we need to safeguard its future.
Humans and animals need oxygen to exist.Tiny plant-like organisms(微生物) that live in the sea are responsible for at least 50%of the oxygen on Earth.Like land-based plants,these organisms capture sunlight and transform it into the energy they need,producing oxygen as a by product.They also consume carbon dioxide from the atmosphere,transferring it deep into the ocean.
The ocean absorbs huge amounts of heat from the sun."More than 90% of the warming that has happened on Earth over the past 50 years has occurred in the ocean, "according to the US National Oceanic and Atmospheric Administration.That heat tends to be at its most intense nearer the equator (赤道) ,with the water nearest the surface warming the most.Sea currents then transport that heat around the world:north and south,towards the poles.As some of the sea water evaporates(蒸發(fā)) it becomes denser and heavier,due to its relatively higher salt content.That causes it to sink,taking some of the warm water deeper.
Fish is on the menu for billions of people around the world every day.It accounts for almost16% of all animal protein consumed globally.Of course,there's more to seafood than fish and other sea creatures.A range of algae(藻類) and sea plants are also commonly used in cooking.The oceans,if properly managed and maintained,could form an important part of a sustainable approach to feeding the planet's growing human population.
The ocean is also home to an abundance of life.While estimates on the number of species that live in the sea exist,no one knows with absolute certainty what that number is.According to the US National Library of Medicine's National Institutes of Health, "91%of species in the ocean still await description."That's due in no small part to the vastness of the oceans,which cover around 70%of the planet's surface and are up to 11,000 metres deep.The number of yet-to-be-discovered creatures living in the sea could easily run into the millions.發(fā)布:2024/5/23 20:38:36組卷:1引用:0難度:0.6
