A global analysis of Earth's threatened and endangered species has changed our scientific understanding about how much climate change is affecting wildlife.
The research, published Monday in the journal Nature Climate Change, shows that 47 percent of mammals and 23 percent of birds have been negatively affected by our changing planet. Those figures are shockingly larger than previous assessments, which have shown 7 percent of mammals and 4 percent of birds were affected. Of the 873 mammal species looked at, 414 are hurt by climate change. For threatened birds, 298 of 1,272 species are experiencing negative effects, according to the findings.
However, a new study follows the analysis of threatened wildlife shows that the biggest threat to wildlife is not climate change, which gets a lot of attention, but human activities, including logging (伐木), hunting and farming. Today, three-quarters of Earth's land surface faces “human pressure", according to a global analysis professor Watson carried out in August.
When it comes to the effects of human activities on wildlife, Watson said, most studies look at what might happen to a population in the future, perhaps 50 or 100 years down the line. The problem with such forecasts is that they are absolutely unhelpful for the here and now.
“Nature is extremely resilient (能复原的) if you give it a chance," Watson said. “But the big thing is acting now, not in 20 to 50 years' time. Not make climate change and“human pressure" a future threat, but take action now. Because every day, every minute, which you delay, you lose those opportunities."
1.What has been found about the effects of climate change according to the passage?
A. Human activities are suffering severe disaster due to the climate change.
B. The species affected by climate change are more than people thought.
C. More than half of the mammal species were affected by climate change.
D. Three-quarters of Earth's land surface has been damaged by climate change.
2.What does the underlined “they" refer to?
A. Human activities. B. Negative effects.
C. Assessments. D. Forecasts.
3.What's the attitude of Watson towards the recovery of the environment?
A. Optimistic. B. Pessimistic.
C. Doubtful. D. Uncaring.
My mother, a nurse at Stony Brook University Hospital, worked at night so that she could come home in time to send me to school. She'd sleep during the day and be ready when we returned home before heading out again in the evening. This went on for 23 years. She never complained (抱怨). No matter how tired she was, she always had enough energy to be my mom.
She often had to work on Christmas, Christmas Eve or New Year's Eve, and sometimes Thanksgiving, which made me upset. However, before holidays she always decorated the inside and outside of our house. She'd also have cookies baking in the oven, a holiday-themed movie in the VCR, and music playing throughout our house for us. But when it was time to go to work, there was no room for debate. “Why do you have to work on this day of all days?" I'd ask sadly. "They need me, too, dear son," she'd respond, compassion (同情) in her tone.
For a long time I didn't understand why she should care so much about those sick strangers. Recently, as my grandmother became ill, I found myself spending more time in hospitals. The scenes I saw in the hospital made me see the different side of my mother. The nurses checked heart, blood and oxygen levels, made sure patients were comfortable. They lifted patients in and out of bed and helped them to the bathroom. Beyond their duties, the nurses displayed consideration for each patient.
What I saw helped me to understand why my mother was devoted to her occupation. I was filled with more admiration for my mother.
