根据“Cows that eat the plant give out 99 percent less methane than others. Red seaweed only needs to make up 2 percent of a cow’s diet to stop them making lots of methane.”可知,给牛添加红藻可以有效阻止甲烷的产生,可推测因为甲烷污染环境,所以要改变牛的饲料。故选B。 (4)题详解: 判断...
Cows that eat the plant give out 99 percent less methane than others. Red seaweed only needs to make up 2 percent of a cow's diet to stop them making lots of methane.The problem is that there is not enough red algae to feed the world's 1.5 billion cows. Scientists say it would ...
And animals like cows and sheep produce, methane is a major product in their digestive tracks. It Makes its way into the atmosphere which you might call the usual channels. 而像牛和羊这样的动物产生,甲烷是它们消化道的主要产品。它使其进入大气层,你可以称之为通常的渠道。 The newsnight was offs...
Methane gas emitted by cows and other livestock does have a significant impact on the amount of greenhouse gases in our atmosphere, which are the main culprits behind climate change and global warming. While farts aren’t the only way cows are expelling methane, it is, at least, accurat...
You may know that climate change is a problem for the world.But do youknow that cows are making this problem worse?When cows digest(消化)theirfood,a powerful greenhouse gas methane(甲烷)--is produced.And it getsinto the air when cows burp(打嗝)or fart(放屁).Agriculture is one of the ...
It remains unknown whether dairy cows with more reactive temperament produce more enteric methane (CH4) and are less bioenergetically efficient than the calmer ones. The objectives of this study were (a) to evaluate the relationship between cattle temperament assessed by traditionally used tests with...
It’s clear that we can make better use of land and water if we produce crops instead of meat. Raising livestock also leads to rising global temperatures. Animals such as cows, pigs, and sheep release(释放) methane—a greenhouse gas that causes global warming—when they pass wind(放屁). ...
Cows, along with goats, sheep, buffalo, and even camels, are known as ruminant animals, and all of themburp methane. This powerful greenhouse gas comes from the rumen, which is the first of the four sections in a cow's stomach, and most of it is belched—despite folklore about gases ...
While this job might sound pretty odd (and very gross), it actually serves an important purpose. Manure inspectors check the manure of animals such as cows to make sure that it is free from any dangerous diseases or contaminants that could affect the people that consume their products. ...
These concrete cows release much less methane than the real thing. So yeah, I get it—I know why my environmentalist friends don'twantto know more about the huge environmental costs of their diets and the “outstanding effectiveness” of eliminating even some meat. Butthe fact that only 6% ...
