Worldwide, between 1961 and 2016, fish consumption increased faster than meat consumption, and grew twice as fast as the human population. All of these fishy dinners have reduced marine fish stocks to a point where a third of global fish stocks are now classed as "overfished". Fishing also has negative impacts on non-food species in the ecosystem, and pollutes the waters with fishing waste. Temporary fishing bans may help, but what if we banned fishing altogether?

One thing is for sure: the ocean would hopefully become a better place for marine species. Recent years have seen plastic products much less used as the public has woken up to the effects of marine plastics. But few people realize the contribution that fishing makes. Pieces of abandoned fishing tools account for about 10 percent of all marine litter, and according to a 2018 study, 86 percent of the big pieces of plastics floating in the "Great Pacific Garbage Patch". Without fishing, we'd also wipe out emission from fishing boats. One 2014 study claimed that fishing industry was actually highly fuel-consuming, like lobsters, with some boats using 20,000 liters of fuel to catch a single ton.

However, what we must not forget is that our planet is highly dependent on fishing in various ways. Around the world,40 million people earn their living directly from catching wild fish, while another 19 million are employed in relevant industries. A total ban on fishing would make it hard for them to put food in their families' mouths. Moreover, seafood is a major source of protein across Southeast Asia and islands in the Indian and Pacific Oceans. So while in Europe or the US people could eat more meat or soy products to make up for lost protein, there could be food shortage in communities with little land-based farming.

Though not a realistic choice, a total fishing ban is an interesting thought experiment, which may throw light on how man can get along with marine species. After all, the damage fishing does to the entire ecosystem and the pollution it brings about are becoming so enormous that it's time we did something to change it.

【推荐1】Cybercrime refers to any criminal offence related to the Internet. Internet crimes have been classified into four categories. First, they can be related to a lack of proper Internet security, such as downloading or deleting other people’s files without permission, and spreading computer viruses. The second are crimes usually committed without a computer, but can occur over the Internet. For some criminals use the Internet to cheat others of their money. Third, websites which offense information or encourage hatred and violence are named. Last, there are related to intellectual property (intellectual property is a design, patent, book, etc. law prevents other people from copying).

All Internet users are affected by cybercrime in one way or another. However, crime against a private organization in the USA, showed that 45.6 percent of the 351 biggest company government agencies had had their security systems broken into in the previous year. Security consultants tell us that cybercrime is costing firms worldwide hundreds of billions of dollars every.

Considering how bad the situation with cybercrime against companies has become, many people wonder why so little is known about this. The main reason is that most cybercrime is not reported. Until now, most companies have been unwilling to report cases of cybercrime. They fear that by doing so, they will lose customers, who may think that the company cannot protect their confidential information or their money.

All of this is made more difficult by the legal situation regarding cybercrime. Cybercrime is so new that many governments have not yet passed laws against it, and there are many holes in the legal systems. In addition, most countries do not have arrangements for dealing with suspects from other countries who may have committed cybercrime. Thus, it is difficult to catch criminals of cybercrime.

The only answer to this problem is international cooperation. Governments must join forces to keep up with the advances in technology used by the criminals. It is also important to draft new laws and negotiate international standards for fighting cybercrime.

【推荐2】Scientists recently have discovered a new species of bat that has bright orange for and black wings. They later named it Myotis nimbaensis in the journal American Museum Novitates.

Jon Flanders, who works at Bat Conservation International (BCI), was leading a team with eight other researchers in the Nimba Mountains in Guinea where they found the orange bat. Many bats live in the mountains’ old mineshafts (井筒) that are now unsafe to enter, so researchers placed nets at the entrances to trap bats while they flew. One night in January 2018, a brightly colored bat standing out among its dark-furred neighbors was also caught in the net.

“The color is just unusual. Its wings are black with orange fur. There aren’t a lot of orange bats in the world. I don’t tend to work with that many brightly colored bats. It’s definitely an unusual one for me,” Flanders says.

There are about 1,400 bat species in the world, including a few orange ones in China and South America — far from Myotis nimbaensis’s home in West Africa. For the past several years, more than 20 new bat species have been added to the list. However, those discoveries usually come about when scientists tease (梳理) apart the small genetic and physical differences between nearly the same species.

“Experienced researchers went out in the field, caught an animal, and said, ‘This is something we can’t identify.’ That’s much more unusual.” says Nancy Simmons, the American Museum of Natural History’s director of mammals.

To make sure that they had found something new, the team recaptured (重新捕获) the first bat they had found and compared it with specimens (标本) of other species. After doing some research, the team concluded that the new species of bat is at least five percent different than the closest related species, reports The Times.

Next, the scientists hope to study more about Myotis nimbaensis’s ecology — where it lives, what it eats, and what it needs in a habitat.
