1 . Many people want to grow their own food in their own backyard, but they don’t know how to start. This article will teach you how to start!
Find out what plants to get. Get plants that can grow in your area, and make sure you plant them at the right time of the year.
Buy your plants and fertilizers. You can either get seeds or get plant seedlings. Go to your local nursery and see what they have. Get fertilizer as well.
Plant your plants in the garden. Use a hand shovel and dig a small hole big enough to put your plant in. Water your plant before you put it in so you can wet the root ball. Sprinkle (撒) in a little bit of fertilizer and put your plant in.
For seeds, stick your finger into the dirt where you want to plant the seed until the dirt reaches the second joint on your finger.

4 . In the eyes of many environmentalists, the world appears to be getting worse. They believe, the natural resources are running out and the air and water are becoming ever more polluted. But if we check the facts, things look different. Energy has become more abundant, not less so. Fewer people are starving. What seems to cause this gap between perception and reality?
One factor is the prejudice in scientific research. Scientific funding goes mainly to areas with many problems. That may be wise policy, but it will also create an impression that there are more potential problems than actually exist.
Secondly, environmental groups seek attention from the mass media. They also need to get continuous financial support. Understandably, perhaps, they sometimes exaggerate (夸大) their arguments. In 1997, for example, the World Wide Fund for Nature issued a statement titled: “Two thirds of the world’s forests lost forever”. The truth turns out to be near 20%.
The media can add to confusion too. People tend to be more curious about bad news than good. Newspapers and broadcasters are there to provide what the public wants. That, however, can lead to significant misinterpretations. For example, when a natural disaster happens, the media usually highlights the negative parts, giving more attention to the disaster’s details and what happens afterward. This flood of bad news can make people think that such events are more frequent or serious than they actually are. Consequently, people may develop a sense of insecurity, despite statistically low probabilities of similar events happening to them.
Another factor is people’s poor perception. People worry that vaccines can cause severe side effects or long-term health problems. Despite extensive scientific evidence demonstrating their safety and effectiveness, some individuals remain hesitant due to unfounded fears.
It is crucial that we look at the facts if we want to make the best possible decisions for the future. It may be costly to be overly optimistic – but more costly still to be too pessimistic.

5 . The birth of a male white-tailed eagle signals the success of the Roy Dennis Wildlife Foundation (RDWF) and Forestry England project to return these iconic birds to their original widespread locations along the southern coast of England. The last time a white-tailed eagle chick grew in England, Mozart was working on his opera Idomeneo in Germany
For two centuries these amazing birds were missing from most of the UK, having been wiped out by human persecution by the early 20th century.
In 2020, the parents of the landmark bird were translocated from the Outer Hebrides and north-west Sutherland in Scotland to the Isle of Wight. This is an area with plentiful food to sustain them. It is also a location from which the birds could spread out to cliffs, lakes and forests.
Female G405 and male G471 were two of 25 eagles (16 are still alive) released by the RDWF and Forestry England as part of the ongoing project. And they are one of three pairs to have now established breeding territories in the south of England.
The chick hatched earlier this summer at a nest on private land, the exact location of which is being kept a secret to ensure the welfare of the young bird.
“This is a very special moment for everyone who has worked on, supported and followed this ground-breaking project,” Roy Dennis says, founder of the RDWF. “Restoring a breeding population in southern England, where the species was once widespread, has been our ultimate goal. Seeing the first pair reach this stage is truly incredible.”
The young white-tailed eagle has now been ringed and fitted with a satellite tag (标签) so that its progress can be tracked. A further release of young white-tailed eagles is planned for late summer from the project team’s base on the Isle of Wight.

7 . Weighing a dinosaur is no easy task. These extinct creatures were massive, and for the most part, all that remains are their bones, as their organs and skin have long since disappeared. However, new research has found more than one way to measure the mass of these creatures.
In a paper published recently in Biological Reviews, scientists evaluated the two existing ways that calculate how much a Tyrannosaurus rex (霸王龙) might have weighed. Led by Nicolas Campione from the University of New England, they examined an extensive database of dinosaur body mass estimates from as far back as 1905, with weight estimates for an individual ranging from 3 tons to 18 tons.
In an essay published by The Conversation, Campione explains that for years, scientists followed two rival (对立的) approaches for calculating a dinosaur’s weight. These methods were long thought to be at odds with each other, but Campione’s team found that both techniques are actually quite accurate.
Using limb circumference (肢体周长) to work out an animal’s mass is already widely used across a variety of modern land animals. The same method can be applied to dinosaurs: Researchers essentially measure the bones in living animals, such as the femur (股骨) in an elephant’s leg, and compare that figure to a dinosaur’s femur.
The second method involves calculating the volume of 3D reconstructions of dinosaurs, which serve as approximations (近似值) of what the creature would have looked like when it was still alive. Occasionally, these methods have come to very different conclusions.
David Evans, a researcher at the Royal Ontario Museum, in Toronto, says it’s important to use both methods because dinosaurs, like humans, did not come in one neat package. “There will always be uncertainty around our understanding of long-extinct animals, and their weight is always going to be a source of it,” he says in a statement. “Our new study suggests we are getting better at weighing dinosaurs, and it’s paving the way for more realistic dinosaur body-mass estimation in the future.”

8 . Artificial Intelligence (AI) has greatly sped up how long it takes to sort, label and analyze(分析) animal sounds—as well as to figure out which aspects of those sounds might carry meaning. One day we’ll be able to use AI to build a chat box that translates complex(复杂的) animal sounds into human language. Project CETI is just one organization working toward this goal.
“AI could eventually get us to the point where we understand animals, but that’s hard to deal with and long-term,” says Karen Bakker, a researcher at the University of British Columbia in Vancouver, Canada. “Some species have been on the planet longer than humans. Some species could go extinct before we figure out their language,” Bakker adds. “Besides, the idea of walking around with an animal translator may seem cool, but many animals might not be interested in chatting.”
“Why would a bat want to speak to you?” she asks. What interests her is what we can learn from how bats and other creatures talk amongst each other.“We should listen to nature and ask the animals’ requirements in order to better protect them,” she argues. For example, a system set up to record whales or elephants can also track their locations. This can help our boats avoid whales or protect elephants from poachers (偷猎者).
Protection is one goal driving Project CETI. “If we understand sperm whales better, we will be better at understanding what’s troubling them,” says Gašper Beguš, a linguist at the University of California, Berkeley. Learning that a species has something very similar to language or culture could also inspire people to work harder to protect it.
When we protect an animal that has some version of language or culture, we’re not simply protecting nature and we’re also saving a way of life. Marine biologist Denise Herzing says that animals are supposed to have a healthy environment so that their cultures can develop well.

9 . A group of clams (河蚌) recently caught people’s attention after an article was posted by China Science Communication online. Although these clams are usually regarded as nothing more than delicious food, they work to monitor the local water quality in Poland.
Gruba Kaska pumping station, which stands in the River Wisla, helps provide millions of liters of water to Warsaw, the capital of Poland. However, one particular concern for the water quality has been heavy metals, and researchers sought help from nature to solve this problem.
Clams are sensitive to pollutants in their environment as they filter (过滤) water to feed on microorganisms. They shut their shells immediately after detecting “dangerous” water.
Based on this, the researchers selected eight clams at a time and recorded the natural opening of their shells. After the clam “employees” become accustomed to the local water, they are placed in a specially designed container. With sensors stuck onto their shells, the clams are connected to a system that records how wide the shells are open. If four or more clams close their shells at the same time, an alarm will be set off and the water supply will be shut down. The result is reliable because the creatures are considering many different factors at the same time, according to ZME Science.
Animals have long been helpers for human activities. Farmers in north Queensland, Australia, have been ordering different species of dung beetles to help clean up cattle waste, according to ABC News. As the number of cattle grows, their waste increases, leading to an enormous population of flies and a worsening environment. Dung beetles, however, take the waste and bury it. This way, they help improve soil quality.
Similarly, cockroaches are used to deal with kitchen waste at several firms in China, according to a report of The Beijing News. About 300 million cockroaches are fed 15 tons of food waste on a daily basis, and they themselves are a good protein resource for livestock.

10 . Sargassum is a kind of floating seaweed (海草) that has been growing in size every year. It looks pretty in the ocean. However, sargassum can almost completely block out sunlight. Important kinds of seagrass suffer when light is blocked by seaweed. As sargassum piles up on beaches, it makes it hard for mother sea turtles to lay eggs, and nearly impossible for baby turtles to return to the sea.
So much sargassum piles up on beaches, and it breaks down slowly, giving out a bad smell like rotten eggs. “Even when governments clear the seaweed from beaches, they face problems of getting rid of it. Heavy machines can put turtle nests in danger. Some people have thought about using sargassum as a fertilizer (肥料), but it contains harmful heavy metals. So far, removing these harmful metal s costs too much to make it worth doing,” said the scientist Steven Kelley.
Sargassum grows faster in warming oceans, so climate change is definitely part of the problem. But scientists believe the unusual growth of the seawood is also caused by huge quantities of fertilizers washed into the ocean from farmlands.
Scientists and students are working hard to figure out how to deal with sargassum. Some suggest using sargassum as a building material, or possibly a fuel. One unusual solution is to drop it deep in the sea by using robots. Sargassum takes in huge amounts of carbon dioxide (二氧化碳) as it grows. Removing carbon dioxide from the atmosphere is one important part of fighting the climate crisis. Sargassum could deal with this carbon dioxide in the deep ocean. Scientists are still testing this idea to see if it will work.
For now, scientists say the quickest solution is to stop filling the ocean with fertilizers. It is wise for farmers to change the way they farm. Moreover, the seaweed’s growth can have serious effects on islands that depend heavily on tourism and fishing. Island communities play a role in cleaning up the seaweed and promoting responsible tourism. At the same time, officials have to work towards changing policies to solve the issues.
