Green Roofs Are An Urban Paradise


Green roofs are pretty great because they assist in flood prevention and can grow crops. Indeed, green roofs are growing in popularity around the world because they are great for cleaning air and cooling cities too! It’s almost as if many urban problems can be solved by converting unused space into usable green environs.

In Chicago green roofs are being planted throughout the city and are proving to be very beneficial. The New Republic decided to reveal the mini-paradises that these small roofs can create.

By 2050, 2.5 billion more people are projected to leave the countryside for the city; in the United States alone, urban land will more than double by 2100. Faced with what scientists call “the urban heat island effect,” cities around the world are encouraging the development of roof gardens. These blankets of wildflowers, grasses, and sometimes even vegetables reduce water runoff, absorb carbon dioxide, and lower temperatures. Chicago is home to the world’s largest rooftop farm: The two acres of land atop a soap factory supply a million pounds of vegetables a year.

It’s Time To Divest

The use of coal to generate electricity is coming to an end, and one of the many reasons coal’s time is up is thanks to divestment. Divestment of fossil fuels has been argued on university campuses for years and started largely as a moral argument that we shouldn’t profit off the reckless destruction of the panel. Since then the movement has evolved to the world of large investment companies because it also makes economic sense.

As global consciousness of the threat of climate change increases there is more and more reason to not invest in the fossil fuel industry. What’s more is that the low price of oil and the successes of renewable energy sources has made the case for divestment stronger.

The divestment movement shares a name and even a bit of the same emotional urgency as the campaign decades ago to get business to pull out of South Africa to press for change in the country’s apartheid system.

“I think that divestment can play the role of accelerating the development that we really need — we really need as fast as possible to get the carbon out of the energy system and divestment is one tool of doing it,” Reverend Henrik Grape of the Church of Sweden said on the sidelines of a conference in the European Parliament. The Church of Sweden decided in 2008 to get rid of its fossil fuel assets.

The movement today can count heavyweight investors like Norway’s sovereign wealth fund, insurance giants Axa and Allianz, major European universities, cities and churches among its supporters. All have made some form of commitment to pull cash from coal assets and, in some cases, other fossil fuels too.

Economic Growth No Longer Tied To Increased Carbon Output

People used to (and some lacklustre individuals still) argue that environmental regulations will wreak economic havoc, hopefully we’ll no longer listen to such irrational arguments. For decades environmentalist and knowledgable people have used data to prove that economies can grow while also protecting the environment. Turns out, the data was right.

The International Energy Agency has announced for the last two years carbon dioxide emissions remain unchanged even though the global economy has improved. There is still room for improvement around the world so it’s even possible to see a decrease in carbon dioxide output while having an increase in economic activity.

“The new figures confirm last year’s surprising but welcome news: we now have seen two straight years of greenhouse gas emissions decoupling from economic growth,” IEA executive director Fatih Birol said in a news release.

The change is because of the rapid adoption of renewable energy, especially for electrical generation, the IEA said.

Electricity generated by renewables accounted for around 90 per cent of new electricity generation in 2015, with wind alone producing more than half of new electricity generation.

The IEA’s conclusion that economic growth can continue without needing increased amounts of fossil fuels is preliminary, like its data, which will be explored in a more complete report in June.

Shower Once a Week

In the developed world people tend to use more water than they should, in fact water consumption in many nations have done irreparable damage. Canadians are really bad at water conservation and we have a lot to learn from other places in how we regulate our water usage. Governments can only do so much with policy to curb industrial and individual usage. There is something you can do everyday to help lower your impact on the ecosystem: shower less.

Yes, you should spend less time cleaning yourself. Showering everyday isn’t good for your skin and it’s really really really (like really) bad for the environment. Even cutting out one shower a week can save you time, money, and your local ecosystem.

The daily bath or shower, then, is terrible for the environment and our bank balances. That’s one reason I have reverted to a weekly shower, with a daily sink-wash that includes my underarms and privates. But there are health consequences too. I first became aware of these when I was a touring ballet dancer and met a friend whose skin had been severely damaged by excessive use of soap products. He was condemned to treat himself with medical creams for the rest of his life. According to dermatologist Joshua Zeichner, parents should stop bathing babies and toddlers daily because early exposure to dirt and bacteria may help make skin less sensitive, even preventing conditions like eczema in the long run. The American Academy of Pediatrics recommends three times a week or less as toddlers’ skin is more sensitive; and as the elderly have drier skin, they should not be frequently washing all of their bodies with soap.
