Eating Jellyfish Could Come to the Rescue

According to the IUCN Red List 32,000 species are threatened with extinction—everything from birds and mammals. Despite national and international efforts being gathered to protect

Between 2006 and 2014,92 vulnerable or threatened 【小题3】 were being caught, recorded, and sold. When they are sold, it is 【小题4】 that fish and invertebrate (无脊椎的) species are required to be 【小题5】 according to species, so consumers have no way of knowing what they’re eating.

It is stressed that only a/an 【小题6】 view of the real problem is shown. “A lot of the ‘seafood records’ are listed in groups like ‘marine fish’. Here we didn’t look at those vague records, we only looked at records where the actual species was listed — so we’ve made a huge 【小题7】 of the actual catch.

There are some ways to untie the mess we’re creating in the world’s oceans, including 【小题8】 our idea of seafood to include jellyfish. That might sound a little off the theme, but it’s not the first time scientists have suggested it as a food source.

There are other ways to help keep the lovely marine lives off the menu. “We need to improve the labelling of seafood so that consumers can have all the information to make a/an 【小题9】 choice,” conservation scientist Carissa Klein told Science Alert.

And these choices, at least in some places, are easier than you might imagine. In Australia, where the researchers are based, there’s even official guides providing the 【小题10】 future both on your table and at sea.

Growing up in Kenya, Lesein Mutunkei, together with his family, always celebrated significant 【小题1】 by planting trees, which motivated him to protect the environment. It’s what the now 18-year-old soccer player treasures, especially since Kenya has an ongoing problem with deforestation (滥伐森林).

Mutunkei follows in the footsteps of the late Kenyan Nobel Peace Prize winner Wangari Maathai, who founded the Green Belt Movement in 1977. This initiative (倡仪) 【小题2】 the planting of over 51 million trees to date.

In 2018, Lesein decided to start a movement of his own. He 【小题3】 by planting one tree for every goal he scored during a football match. He called it Trees4Goals, and it has grown so much that he now plants 11 trees, one for each member of his team, every time he gets a goal. Through this, he wants to inspire young people, 【小题4】 his fellow athletes, to follow in his footsteps, take the 【小题5】 of nature seriously, and promise to plant trees every time they score. So, as a consequence, some of them have adapted this practice for their sports. “Seeing that they’re taking that responsibility 【小题6】 the project I started, for me, that is the biggest achievement,” he said.

The initiative has caught the attention of English football club Arsenal and Kenya’s Ministry of Environment and Forestry, which he now works with regularly and gets advice from.

Like Green Belt Movement, Trees4Goals, which has planted 5,500 trees so far, has made it. While Lesein has received some recognition for his initiative, he sets his sights on making it a worldwide phenomenon (现象). “Football is a universal game, and climate change is a universal problem,” he explains. “It has the power to unite, educate and inspire my generation 【小题7】 a safer and greener future.” This is 【小题8】 he wants to work with the world’s biggest football federation FIFA.

As for what others can do to fight deforestation or other environmental concerns, the teenager says it’s important to just get involved 【小题9】, no matter how 【小题10】.

Here’s to guilt-free flying

Maj a Rosen gave up flying a decade ago out of concern for its environmental impact. But when she became a mother and started hanging out with other parents, she didn’t bring it up, even when the conversation turned to flying. It would have 【小题1】 the mood.

Then in April 2018, her home country of Sweden 【小题2】 a tax on aviation (飞行).The climate impacts of flying were on the evening news and the mood changed. Rosen【小题3】 the moment. With her neighbor Lotta Hammar, she launched a campaign called “We stay on the ground”, which has【小题4】10,000 people to commit to avoid flights in 2019.

Kudos. But here’s the 【小题5】 truth: in the grand scheme of things, barely anyone will follow suit. The 【小题6】 classes tend to have a lot to say about the eco benefits of avoiding meat, cycling and eating locally sourced food. But that 【小题7】 generally disappears when it comes to flying.

We can’t rely on international 【小题8】 to stop aviation emission either. Yes, the UN has fixed up a deal to cap aviation emissions beyond 2020. But it lacks real bite, allowing airlines to continue emitting carbon provided they offset (抵消)it.

All this means we could really do with green tech riding to the rescue. Here, at least, there is a little good news. Even rather simple measures like freeing planes to fly in straighter lines could 【小题9】 cut carbon emissions. Hybrid (混合动力的)electric aircraft are also the pipeline. And we already know that planes can mix up to 50 per cent biofuels into their tanks and fly safely.

It’s time to redouble our【小题10】 to make planes green. In the meantime, if you are still looking for a New Year’s resolution, you might want to think about joining those 105000 Swedes.
