We need a luxury tax, do not throw away your Halloween garbage, no cellular antennas near schools  and other news to read on Tuesday, November 5th.   1- "We desperately need a luxury tax." Yancey Strickler is co-founder and former CEO of Kickstarter, and worries about the growing gap between the richest and the poorest in the country. According to him, the strictly financial value brings no real value to the economy unless that value is transformed into something else. "It's been 50 years that we think only in terms of financial value, and our situation is worsening every day," he says, saying he favors a wealth tax "that would cover the needs of base of the famous Maslow pyramid, "he adds, on Yahoo .   2- Do not throw anything! This organization will collect your Halloween waste for you. Most candy and candy bars are not recyclable and generally end up in landfills. To counter this phenomenon, traders have joined the international organization Terracycle to recover all Halloween waste that will be reported to them over the next few days. Terracycle offers those interested in boxes in which to deposit this waste. These will then be reused, recycled or composted, depending on the type of material that composes them, explains the management of the shop La Looma, St-Bruno-de-Montarville, on his blog .   3- Apple and Disney very seriously threaten Netflix. With Apple TV + launched last week and Disney + coming up next week, the war of video-on-demand services is officially launched, and it seems that Netflix and Amazon will pay the price of this new competition. "All these players are not going to survive," predicts PK Kannan, a marketing professor at the University of Maryland, Fortune .   4- How helicopters protect cannabis plants from freezing. The plant manager at cannabis producer 48North took great steps to protect his plants from cool nights: he asked a helicopter pilot to fly over his crops. The air movement caused by its propellers pulls moisture from the ground into the air, and pushes warmer air towards the plants, which reduces the effect of cold on the shoots, says BNN.   5- The number of the day: 53% (the share of children under 11 years old who owns a smartphone in the United States). This proportion rises to 84% in adolescence, according to a survey of the firm Common Sense Media taken over by NPR .   6- Antennas of cellular networks too close to schools scare parents. Residents of a neighborhood west of Toronto boarded the barricades earlier this fall, worrying that two long masts located less than 75 meters from the local elementary school, that they thought they were only there to support flags, were in fact two antennas of the cellular signal transmission of Freedom Mobile. These parents are demanding that these antennas be relocated, despite the fact that Health Canada and the Canadian Cancer Society recall that there is no link between the wireless networks of these networks and the disease. "Young children are so much more sensitive to all these pollutants in the environment," says a professor at Trent University in Peterborough.CBC .   7- Peaches and aubergines soon censored on Facebook? Facebook and Instagram have decided to end the use of "emoticons or emoticon sequences to the character commonly or contextually sexual" by their users. This is difficult because Facebook does not want to censor the "suggestive elements" as a whole, but still wants to eliminate the solicitation of a sexual nature, which implies the use of images of certain fruits or objects having sometimes such connotation, says Fast Company .   8- Rising sea levels threaten three times more people than expected. Researchers at Climate Central estimate that around 300 million people will see the place where they live flooded at least once a year by 2050, unless the banks and shores are better protected and that we reduce the impact of human activity on the climate. This is more than the 80 million people previously thought to be at risk, a review allowed by a more accurate assessment of the ground level by scientists. "The changing climate will radically transform cities, economies and entire populations in our lifetime," says Scott Kulp, author of the report in question, at The Guardian .   9- India will open 100 airports within 5 years! It is likely to change the face of world trade, the populous country wanting to accelerate its economic growth by facilitating mobility throughout its territory. The ambitious project also includes the construction of 1,000 new roads by 2025 to better connect the country's towns and villages. Prime Minister Narendra Modi's turn comes as India's economy slumps to a six-year low, and the return of solid growth is slow to come on the horizon, says Bloomberg.   10- Here's how to completely eliminate blind spots by car. A young American student has created a project for a science fair that is likely to inspire more than one experienced automotive designer ...
