The world's insects are going down the path of extinction, threatening a "catastrophic collapse of nature's ecosystems", according to the first global scientific review. More than 40%of insect species are declining and third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles.
"It should be of huge concern to all of us, for insects are at the heart of every food web. They pollinate (授粉) the large majority of plant species, keep the soil healthy, recycle nutrients, control pests, and much more. Love them or 1oathe them, we humans cannot survive without insects, "said Prof Dave Goulson at the University of Sussex in the UK.
The analysis, published in the journal Biological Conservation, says intensive (集约型) agriculture is the main driver of the declines, particularly the heavy use of pesticides. Urbanisation and climate change are also significant factors.
"If insect species losses cannot be stopped, this will have catastrophic consequences for both the planet's ecosystems and for the survival of mankind. It is very rapid. In 10 years you will have a quarter less, in 50 years only half left and in 100 years you will have none," said review author Francisco Sánchez-Bayo, at the University of Sydney, Australia.
One of the biggest impacts of insect loss is on many birds, reptiles, amphibians and fish that eat insects. "If this food source is taken away, all these animals starve to death," he said. Such effects have already been seen in Puerto Rico, where a recent study revealed a 98%fall in ground insects over 35 years.
Matt Shardlow, at the conservation charity Buglife, said: "It is thoughtful to see this evidence that shows the pitiful state of the world's insect populations. It is increasingly obvious that the planet's ecology is breaking and there is a need for a strong and global effort to prevent and change these terrible trends."
In our daily life, we have developed a lot of habits, such as, eating habit, study habit, reading habit, etc. However, taking the time to develop a sleep habit is probably the last thing on your mind and some sleep advice simply can't be forgotten. {#blank#}1{#/blank#}.
Watching TV until you fall asleep
It has nothing to do with what you watch —TV news isn't a better pre-sleep choice than TV series. {#blank#}2{#/blank#}. The bright light keeps you awake all the night. So even if you nod off (in front of the TV, for example), you probably won't stay asleep for long.
Sleeping with pets
{#blank#}3{#/blank#}. They get comfortable, and then they move. This goes on all night, and whether you admit it or not, it interrupts your ability to get the level of sleep needed to feel rested.
Eating fatty, heavy foods too close to bedtime
Heartburn (烧心,胃痛) strikes anyone of any age, but it's the most common GI disorder (胃肠失调) in older adults. If you've ever tried to go to sleep after eating a fatty meal, you've probably found the discomfort of stomach preventing you from falling asleep or staying asleep.
{#blank#}4{#/blank#}
Remember how poorly you sleep when you have a fever—turning over and over again, never really feeling rested? Well, heavy exercise too close to bedtime has the same effect — it raises your body temperature so that your sleep is disturbed until your body temperature drops to normal, which may take several hours.
Accepting snoring (打呼噜) as normal sleep behavior
Snoring may seem as common as breathing, but it's considered the biggest sleep killer, and it's linked to several causes: sleeping on your back, being overweight, having a cold, drinking, or taking drugs. {#blank#}5{#/blank#}. For the snorer, it disturbs sleep by awakening him/her every so often in order to breathe normally. For the partner, the noise can be unbearable.
A. Exercising heavily too close to bedtime B. Here are some bad habits you need to get rid of C. Most seriously, it's caused by a dangerous illness D. Here are some suggestions you'll need to follow E. Pets sleep most of the day, and they move a lot when sleeping F. Reducing your body temperature before bedtime G. Rather it's the TV's bright light that is the criminal |
