Coastal erosion is having a big impact on Canada's future by negatively impacting many things. Coastal erosion is causing problems such as rising sea levels, putting human lives at risk, etc. Although coastal erosion may be hard to stop, there's way we can mitigate it.
Rising Sea Levels:
Coastal erosion has been raising sea levels all over the world at a pretty rapid rate. It was stated in an article that I read "Global sea levels have risen at a rate of about 1.7 mm per year over the last century, but recent satellite observations are suggesting that 3 mm per year could be a more accurate prediction of sea level rise in the past decade." The reason rising sea levels can cause damage is because it increases the amount of floods that happen and cause structural damage to buildings.
How Does This Affect Humans?
Coastal erosion can affect many people in different ways. It states in the article that "Canada has 226,000 kilometers of coastline, and up to 600,000 people are currently exposed to rising seas and flooding." This means that rising sea levels due to coastal erosion has caused damage to humans by making it dangerous to live in their home near sea and putting them at risk of experiencing heavy floods in their area.
What Are Mitigations For Coastal Erosion?
Consult Your Community - check with your local officials to see
if they have mitigation or community
plans or suggestions for reducing
erosion in your area. Strategic and holistic
erosion mitigation projects can protect
your home and those of others, too.
Habitat Restoration - Natural coastal habitats can slow waves, reduce wave height,
and reduce erosion. Healthy dunes and wetlands can provide
a barrier between the water’s edge and your property, creating
a first line of defense.
Living Shorelines - Living shorelines stabilize a shore by combining living
components, such as plants, with structural elements, such
as seawalls. Living shorelines can slow waves, reduce erosion,
and protect coastal property
Beach Nourishment - Beach nourishment involves replenishing the sand on a beach
to widen it. However, it is a temporary solution that will not
permanently reduce the risk of erosion.
Coastal Erosion Structures - Seawalls, revetments, bulkheads, groins and breakwaters
may reduce erosion in the short-term. They also have very
high initial investment costs. However, over time, they
can have adverse impacts on the coastline.
Anchor Your Home - Using piles that drive into more secure layers of
the ground is highly recommended, especially for homes that
are older.

Great coastal reflection!-looking forward to more climate connections this week.
