In Canada road salts are one of the biggest causes of pollution. Each year about five million tonnes of road salts are used. Using this huge amount of road salts can lead to damage in vegetation, organisms in soil, birds and other wildlife. The road salts also almost always find their way into waterways where they are a danger to plants, fish and other organisms that live in freshwater. Road salts are necessary because of the amount of snow that we get in the winter, but overusing them is leading to some massive harm to our environment. Road salts are effective when temperatures are between 7°C to minus 10 °C. If temperatures are below it is not very useful. Using the right amount of salt will help out the environment in so many ways. You only need a pill bottle size amount of salt for every square meter of sidewalk or walkway. Other things you can do at home are try to thurley shovel your driveway first. And try to only use salt if it is completely necessary and the temperatures are between 7°C to minus 10 °C. You can also help by sweeping us any extra salt and disposing of it properly.
