(A)
Children's average daily time spent watching television or using mobile device incread from 53 minutes at12 months old to more than 150 minutes at 3 years old, according to an analysis by rearchers at the National Institutes of Health. Children aged 7 were more likely to spend the highest amount of screen time if they had been in bad home-bad childcare or were born to first-time mothers.
"Our results indicate that screen habits begin early." said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD). "This finding suggests that interventions to reduce screen time could have a better chance of success if introduced early."
In the rearch, mothers of4.000 children responded to questions on their kids' media habits when they were 12,18,24,30,and 36 months of age.
The American Academy of Pediatrics recommends avoiding digital media exposure for children under 18months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5years of age. In the current study, rearchers found that 87% of the children had screen time exceeding(超过) the recommendations. However, while screen time incread throughout infancy(幼儿期)。 after 8 years of age, screen time fell to under1.5 hours per day. The rearchers believe this decrea relates to time consumed by school-related activities

During a decline in tourism,one national park in Thailand has en a dramatic ri in “visitors”recently. So many are the hermit crabs (寄居蟹)flooding into the otherwi empty beaches of Koh Lanta that shells(贝壳)for them to live in have become in short supply.
The Thai government moved quickly to ea the housing shortage,launching a public appeal for empty shells that netted over 200 kg. On December 5 the were distributed around the park in a ceremony.

The shell drive was part of a government initiative to “regain the balance of nature”. “I have instructed all national parks to do whatever it takes,” says Varawut Silpa-archa,the minister for natural resources. His inspiration comes from the pau in tourism brought on by COVID-19. A ban on international visitors and the closure of national parks have helped nature recover,bringing endangered leatherback turtles back onto Thai beaches. In the coastal provinces of Phang Nga and Phuket,turtles have laid the largest number of eggs for 20 years.

From now on,all national parks will be required to clo for a short period during the off-ason and to limit the number of tourists through a rervation system when they are open. Although such restrictions mean reduced earnings from tourism in the short term,in the longer run more parks may help to keep the tourists coming.
