1.0 INTRODUCTIONThe resource issue I am writing about is salt run off. It is important to the sustainable development in Canada is we will have salty drinking water. I think sand is a better option because it will insure that there is an equal balance between environmental, social and economic perspectives to reach sustainable development. Sand is better for the ecosystem, less expensive than road salt and results in cleaner drinking water in our cities. If we don’t make the switch from road salt to sand soon, we will run in to many issues with our winters potentially getting harsher. Sand is better for the ecosystem. Salt contaminate our lakes, sand doesn’t. “Chloride levels have been increasing in Lake Ontario since the mid-1990s … due to the associated use of road salt on many roads” (https://goo.gl/d3rV43, Dec 18th) Salt can get into our lake and kill some species that do not deal with salt well. Sand is already in our lakes, and just sink to the bottom. Another reason why sand is better for the ecosystem is salt dehydrates our vegetation. Salt sucks the water out of our plants, sand does not. “Salt damage occurs on plants when salt is deposited by spray from passing cars on stems and buds of deciduous woody plants and on stems, buds, leaves and needles of evergreen plants. Salt spray can cause salt burn on buds, leaves and small twigs. Salt spray can also cause damage by desiccating the bud scales, exposing tender tissues of the developing leaves and flowers.” (https://goo.gl/SVSyKT) Salt damages the soil. Salt can make soil inhabitable to most plants because most plants are not able to live under salty conditions. Sand does not damage the soil because it does not dissolve into it. the salinity that the salt puts in the the soil water makes the environment inhabitable for most plants. Using sand as a snow removal option is a better choice for all including the species in the lake, and humans.Sand is less expensive than road salt. Sand costs half as much as road salt does by the ton. Sand is 25-40 dollars per ton, road salt is around 60 dollars per ton. You will be saving at least 33% on sand. 2 years ago Toronto spent 85 million dollars on snow removal, 11 million of that was used on road salt. You won’t have to use as much sand as you do salt. (the more you use the sooner you will have to buy more of the product.) Salt also eats away at our cars, so you will have to fix it which will cost more money. During extremely low temperatures, salt becomes less efficient so you have to use more of it. This does not happen with sand so you will not have to use as much. The Elliot lake mall collapse occurred because years of no one noticing rust on the side of the mall, and it caved in. Salt can harm your pets. If salt builds up into a puddle, your pets can lick it and it could make them dehydrate and it is bad for their bodies. That would not happen with sand. When dogs step on the salted sidewalks, they can experience painful burning, and cracked bottoms of their feet. If dogs lick the salt it can cause inflammation in the mouth. (https://goo.gl/79Xr6P) Sand is a better option for your ecosystem because there are many cons to using salt. Sand is better for the social perspective of clean drinking water. Sand does get into our drinkable water, but it is easily filtered out. “In Ontario, for instance, Lake Simcoe’s chloride levels have climbed five-fold in the past 10 to 20 years” (https://globalnews.ca/news/3375121/road-salt-freshwater-lakes/) “84% of US streams measured in a recent research publication had increased chloride concentrations.” (https://www.wired.com/2015/03/road-salt-polluting-rivers/) Salt gets into the water and changes the taste of it and can affect our long term health. the world is 70 % water, but we can only drink around 2.5 % of it. With using salt, we are making that 2.5% smaller. We get a lot of our water from our lakes, so when salt gets into it, we lose a lot of it. Almost 50 % of the people in ontario drink water from lake ontario. (https://goo.gl/SByRGf) If we don’t have clean drinking water then we turn to bottled water. The plastic that the companies use to make the bottled water frequently does not end up in the recycling, it ends up in backyards, lakes, and oceans. This is worse than having salt in our lakes. in the process of making plastic bottles, a lot of fossil fuel are let into the air. The equivalent amount of oil used in making one plastic bottle is if you fill it up to a quarter full. Think how many plastic bottles are used each year. That will only get bigger if we damage our tap water usage. 5 CONCLUSIONSalt run off can endanger a sustainable development in canada because it can harm our social, economic, and environmental needs. It is clear that sand is a better option when it comes to making a sustainable development in Canada. Sand is better for the social perspective of clean drinking water, sand less expensive than road salt, and sand is better for the ecosystem. To conclude, we need to make a switch from sand to salt, if we don’t act soon then many environmental, social, and economic issues that can become bigger.
