The advertising around plastics highlights how recyclable it is, but in reality plastics are a pollutant that barely get recycled in a meaningful way (this is why the 3Rs are in a particular order: reduce, reuse, recycle). Plastics come in all sorts of densities, colours, and strength, but are traditionally made using petroleum. The source of most plastics is unsustainable and the waste generated by plastics after use is equally unsustainable. In fact, the waste produced by plastics has led Canada to categorize plastics as toxic!
By declaring plastics toxic more rules and regulations will need to be followed to ensure that the damage done to the plant (and people) are limited.
A 2020 government science assessment found ample evidence that plastic harms the environment, choking seabirds, cetaceans and other wildlife. The findings form the basis of the government’s decision, as substances can be considered toxic under CEPA if they harm the environment and biodiversity, human health, or both.
In October 2020, ECCC released a proposal to deal with the problem. Under the proposed rules, Canada will ban six single-use plastic items, like straws and six-pack rings, create incentives for companies to use recycled plastic, and force plastic producers to pay for recycling.
Obviously, a diet change to consume less meat is good for animal mortality but what you might not know is that a mass shift to plant based diet is good for everyone’s health. New research has identified that the pollution caused by meat production is responsible premature death of over 17,000 in the USA alone. Therefore, the more people who reduce their meat consumption the less harm will be done to people. Perhaps it’s time to cut subsidies to pollution intensive farms as we aim to reduce pollution and carbon output.
Yes, this is a global problem which requires systemic changes; however, you can do something about by simply switching your beef patties for any plant based ones.
The researchers estimated air quality deaths related to 95 different agricultural commodities in the United States, using data from the U.S. Department of Agriculture. Subsequently, they estimated the per-unit annual impact of 67 products from 11 food groups. Products ranged from beef to beans.
The United Kingdom is taking a step towards a green future by announcing that diesel and gas powered cars won’t be allowed in the country starting in 2030. Older cars will still be allowed, but three will be a ban on any new cars sales that aren’t friendlier to the environment. With any luck, the “need” for cars throughout the country will decrease due to increase transit and better urban design,
Let’s hope that more countries follow the lead of the UK and ban theses pollution machines!
“Now is the time to plan for a green recovery with high-skilled jobs that give people the satisfaction of knowing they are helping to make the country cleaner, greener and more beautiful,” Johnson said in a column published in the Financial Times on Tuesday.
Britain last year became the first G7 country to set in law a net zero emission target by 2050, which will require wholesale changes in the way Britons travel, use energy and eat.
The new date for a ban on new petrol and diesel cars is five years earlier than the 2035 pledge made by Johnson in February.
Cleaning the air and keeping areas cool are what trees do best. A new study has looked into how best to use trees from a purely utilitarian standpoint. Essentially they drilled down to what trees do best and where they can thrive. The researchers cataloged the best places to plant trees based on factors like removing particulate matter from the air and where they can have the greatest impact on local temperatures. As a result their research outlines the most efficient use of money when deciding where to plant more trees.
As always, the best time to plant a tree is today.
There is one catch, though: The tree-planting campaign has to be well-targeted. And that gets a bit complex.
Trees only improve air quality in their immediate vicinity, about 100 feet or so. That means cities need to figure out which neighborhoods benefit most from new trees (typically the densest areas, but also areas around hospitals and schools). They also have to plant species that are most effective at trapping pollution (typically those with large leaves).
Officials also need to account for things like wind patterns and tree spacing and figure out whether they’ll be able to maintain their trees. Plus, if water is scarce, they’ll want to consider drought-tolerant varieties. And they may want to steer clear of trees that increase pollen and allergies.
Barcelona is going to build a road bridge which may be the cleanest bridge yet. Of course it’ll have pedestrian walks and bike paths, however, what makes the bridge really noteworthy is that it will clean the air.
Concrete is notoriously energy-intensive to create so any carbon offset is beneficial. The Barcelona bridge will make use of photocatalytic concrete.
But the real prize of this thing is its basic building material, photocatalytic concrete. The principal of photocatylitics is that ultraviolet light naturally breaks down dirt, both natural and synthetic. It’s that old adage about sunlight being the best disinfectant. Photocatalytic concrete is used with titanium dioxide, which helps accelerate the natural UV-breakdown process, turning the pollution into carbon dioxide, and oxygen and substances that actually belong in the atmosphere.
The actual process has to do with semiconductors and electrons and other things that you may or may not care to read about. (At any rate, the Concrete Society of the United Kingdom does a better job of explaining it.)
An air-cleaning bridge makes for a neat news story and a sci-fi-ish novelty that environmentalists can blog about. But the important point is that Barcelona has taken a piece of infrastructure that exists solely to accommodate car culture, and re-invented it to partially offset the effects of car pollution.
