Fig Trees Figured Out Carbon Storage

- Adam Clare

The humble fig tree can help us in extracting carbon dioxide from the atmosphere by converting it in into stone. All trees remove CO2 from the air and store it in their wood, however as the wood biodegrades the CO2 is released again. Fig trees, on the other hand, combine the CO2 within itself to form stone!

“What was really a surprise, and I’m still kind of reeling from, is that the [calcium carbonate] had really gone far deeper into the wood structures than I expected,” says Rowley, who will present the work at the Goldschmidt Conference in Prague, the Czech Republic, this week. “I expected it to be a superficial process in the cracks and weaknesses within the wood structure.”

How Canada Can Have Affordable Housing

- Adam Clare

Ever since the federal government stopped building housing in the 90s and let the housing market function without intervention the cost of housing in the country has skyrocketed. The lack of action and leadership at both the federal and the provincial levels has led to our current housing crisis. An organization, More and Better Housing, has plotted out Canada can easily solve our housing issues.

Four Pathways to Housing Affordability

  1. Making home ownership and rent more affordable by cutting building costs.
  2. Keeping property taxes and transportation costs in check by allowing more building in convenient locations.
  3. Lowering insurance and maintenance costs by building sturdier homes in safer areas.
  4. Reducing utility bills with energy-efficient homes.

The new report analyzes specific recommendations from the Blueprint, finding that they give governments the tools to drive down five key shelter costs, which make up over 40% of middle-class household budgets.

Cities Address Climate Crisis Faster than Nations

Your local city council is doing more to protect the future than your national leaders. Cities are on the front lines of the climate crisis and are working hard to ensue that their people are protected from the effects of a warming planet. Cities can react swiftly to climate related issues due to a variety of factors and by addressing issues head on cities can solve more than one problem at a time.

And by literally greening their cities, mayors solve a bunch of their citizens’ problems at once. In Quezon City in the Philippines, the government turned unused land into 337 gardens and 10 model farms, while training more than 4,000 urban farmers. The report also notes that Freetown, Sierra Leone, planted more than 550,000 trees, creating more than 600 jobs. In addition to significantly reducing urban temperatures, these green spaces also mitigate flooding by soaking up rainwater. “It is becoming clear, I think, to a lot of municipalities that this type of action will be absolutely essential,” said Dan Jasper, senior policy advisor at the climate solutions group Project Drawdown, which wasn’t involved in the report. “It’s not just about being uncomfortable. This is about protecting people’s lives.”

Cargo Bicycles Are More Efficient Than Cargo Vans

Delivery vehicles are a significant cause of delays in city as they stop and block other transportation modes at a frequent basis. I’m sure everyone can relate to being frustrated while a truck or van blocks a bike lane (or car lane) while they unload. Urban planners and logistics professionals need to think more about using cargo bikes to help with the flow of traffic while also reducing gross emissions. Cargo bikes are actually more efficient than vans when it comes to urban deliveries. This is particularly worth noting when thinking of opening up streets to people as some argue that deliveries are a key reason we need to close streets to people (and only allow vehicles to be on the road).

When delivering goods in central Brussels the electric Bullitt cargo bikes covered 30% shorter routes, and travelled at 16 km/h versus 11 km/h for vans constrained by congestion, according to the study. The cargo bikes were over 2 times faster than vans using 48 min. versus 99 min. on a typical 8.5 km bike route in Brussels urban centre.

Over a month and a half, the cargo bikes delivered 10.1 packages per hour on average, while vans were able to deliver 4.9 packages per hour to the same destinations. Bikes bypass traffic jams, take shortcuts through streets closed to through traffic and ride to within 30 metres of delivery points on average, minimising walking time. Meanwhile, previous studies have shown that vans can spend up to 25 min per stop searching for parking.

Video Games Don’t Harm Brain Development

- Adam Clare

Video games are fun, and they won’t cause harm to your kid’s mental development. Of course, moderation is key since it’s good to experience a multitude of things to do; however, the evidence that video games themselves harm development just isn’t there. So play video games and let your kid play video games.

It is currently the summer so perhaps you should play outside for now though.

“Overall, neither duration of play nor choice of video game genres had significant correlations with the CogAT measures. That result shows no direct linkage between video game playing and cognitive performance, despite what had been assumed,” said May Jadalla, professor in the School of Teaching and Learning at Illinois State University and the study’s principal investigator.

But the study revealed another side of the issue, too. Certain types of games described as helping children build healthy cognitive skills also presented no measurable effects, in spite of the games’ marketing messages.

“The current study found results that are consistent with previous research showing that types of gameplay that seem to augment cognitive functions in young adults don’t have the same impact in much younger children,” said C. Shawn Green, professor in the Department of Psychology at the University of Wisconsin-Madison.
