2 . Roads and railways have made it easy for people to travel around the UK, but have had the precisely opposite effect for insects. Alongside housing developments, transport infrastructure (基础设施) has separated insect habitats, leaving many pollinators (传粉昆虫) stuck on decreasing islands of biodiversity.
A new conservation project aims to address that by creating a network of wildflower superhighways across the UK. The B-Lines network aims to join the dots between meadow habitats, enabling pollinators and other wildlife to move freely between them. Ten years in the making, the B-Lines initiative was launched by the insect charity Buglife on Tuesday and has already generated interest from unexpected quarters. “After the launch, some house builders rang up asking how they could include the network into house building, so it could have a really positive effect,” said Buglife’s Paul Hetherington.
Buglife has spent the last decade mapping potential routes for the insect superhighway. Hetherington said the proposed highway could give the UK’s weak insects a boost and a route out of habitats that become too hot due to the climate crisis and it can make a huge difference in easing declines. “The things that have really hammered pollinators are habitat loss, loss of connectivity of habitat, climate change and pesticides—this deals with everything except pesticides,” said Hetherington.
The B-lines network is not just a concept. Pilot sections have already been completed, including the South Wales B-Lines near Cardiff. “Since that was done, there have been recordings of one of our rarest bees in Cardiff town centre, which shows this connectivity can work,” said Hetherington. And in Norwich, Buglife has been working with Network Rail to plant wildflowers along the track. Anyone living along the proposed route can get involved in the project. All they need to do is let their lawns grow, or even just create a small herb garden, which Hetherington likened to creating a “motorway service station for bees”.

Trees are so important that some people have made it their goal to protect them. We can call these people “tree hugger”. It describes people who support the protection of forests. Today, the term “tree hugger” describes a person who is an environmentalist.
However, calling someone a “tree hugger” is not always seen as a praise.
Some tree huggers do go to extremes to protect trees. Take, for example, an American woman named Julia Lorraine Hill. For 738 days from December 10, 1997 and December 18, 1999, Hill lived in Luna, a Redwood tree in northern California’s Humboldt County. Luna is huge, measuring nearly 61 meters tall and about 12 meters across, which has stood in Humboldt County for more than 1,000 years.

5 . Earth Day is April 22. Every year, people around the world observe the day by helping to care for the environment. They carry out all kinds of activities in an effort to better the planet’s heath.
One way to support this goal is to grow plants native to your area. This helps wildlife like birds and insects that evolved alongside native plants. For many of these animals, plant pollen (花粉) is their food. Native pollinators often cannot recognize non-native plants as food. This means they do not collect the pollen or spread plants’ seeds. Planting non-native species creates so-called “food deserts” for pollinators including bees, birds, bats, butterflies and more.
Doug Taamy is a professor of entomology at the University of Delaware. Entomology is the study of insects. He found that non-native plant species can harm the natural food chain, which can lead to a collapse of the environment. “Plant choice matters,” he said. “The plants we choose to landscape our properties should be determined by how much life can live there.”
Humans depend strongly on insects. Without them, we would have no flowering plants, which would harm the food web that supports important animals. Birds, for example, depend on plants for food and spread their seeds while keeping the populations of harmful insects down.
Insects support plants that provide oxygen, clean our water, capture carbon and add nutrients to the soil. That builds topsoil and prevents flooding. Without insects, the biosphere — the living parts of the Earth — would rot because of the loss of insect decomposers. Humans simply could not survive that, Tallamy said.
In addition to providing food and habitat for insects and other wildlife, native plants are able to grow easily and do not require much care. That means less watering and less fertilizing. The situation is a win-win for gardeners and pollinators.

6 . A tsunami is a series of huge waves that can kill many people and destroy a whole country. A terrible tsunami disaster happened on December 26, 2004.
The word “tsunami” comes from Japanese words. A tsunami can be caused by natural phenomenon such as landslides, volcanic eruptions, large asteroid impacts (小行星撞击地球), and earthquakes occurring underwater or close to a body of water.
A tsunami usually cannot be seen while it travels through deep water.

7 . “What if we treat the ocean as if our lives depend on it? Or, what if we don’t?” World-famous marine biologist Sylvia Earle poses her famous “what if” questions to inspire people to reflect on how they can help save the ocean. In 1998, Time magazine named Earle its first “Hero for the Planet.”
Earle’s move to Florida’s west coast at age 12 is what started a lifelong passion. She says, “That’s where I first fell in love with the ocean.” In 1953, using newly developed equipment, the young scientist became one of the first in her field to scuba dive (水肺潜水). Her first long-term exposure to the ocean depths came in 1970 when she led an all-female research team to study the ocean. They lived under the sea in a submersible (潜水器) for two weeks. When they returned to the surface, world-wide cheer and praise were waiting, especially for Dr. Earle.
Sylvia Earle’s career includes many firsts. In 1979 she became the first woman to walk the ocean floor 381 meters below the surface. In 1990, she became the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration (NOAA).
Through the years, Earle has spent roughly 7,500 hours underwater. During that time, she has become increasingly alarmed by the significant changes she has observed.
The famous scientist fears that the ocean is dying. Climate change, overfishing, the dumping of trash and chemicals and oil spills are just some of the many causes. In order to tackle the problem, Earle formed Mission Blue in 2009. This organization promotes the legal protection and conservation of the world’s oceans. Her plan is to develop “Hope Spots,” protected areas large enough to reverse (逆转) damage and restore the ocean.

9 . There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later, the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a sixweek period in July and August 2003, more than 11, 400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have airconditioners installed in elderly care homes. But this is considered a shortterm solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower”, which uses a covering of bamboo to act as a natural airconditioner.
Shanghai
Shanghai is one of the fastest growing cities on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coalfired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
