2 . On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedo !
Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine life. When asked why he doesn't wear a wetsuit(防寒泳衣), Pugh says, "I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I'm asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message."
It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1.6 degrees Celsius. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.
Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.
This is not the first time that Pugh has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica's Ross Sea as part of his successful campaign to help set up a marine reserve there.

3 . You'll need to take a deep breath before hearing this news. An astonishing 93% of kids around the world live in environments with air pollution levels that are damaging their health, according to a new report by WHO.
Air pollution is to blame for the deaths of 543,000 kids under 5 in 2016, with more than one in four deaths of children under five years old being related to environmental issues. Exposure (暴露)to air pollution can damage the health of kids in a variety of ways, either causing or being associated with everything from low birth weight to childhood obesity and so on.
"The large toll of disease and death revealed (揭示)by these new data should result in an urgent call to action for the global community especially for those in the health department WHO stated. “ Strong action to reduce exposure to air pollution offers an opportunity to protect the health of children. " The report stressed that health experts should communicate with families , communities and policy-makers about the serious risks of air pollution exposure. " Although more researches into how air pollution affects children's health will continue to be valuable, there is already evidence to justify strong, swift action to prevent the damage it clearly produces," WHO added.
Disease caused by dirty air is more common in low-and-middle in come countries, especially those in Africa, South-East Asia, and Western Pacific regions. Poor countries in these areas have the highest levels of exposure to household air pollution due to the use of polluting fuels and technologies for basic needs like cooking, heating and lighting.
Advised solutions include cleaner transport , cleaner cooking and heating fuels and technologies energy-efficient housing and urban planning, safer industrial technologies and better waste management.
