Dear Division 16,

For this week’s assignment, please read the document produced by the government in BC about rising tides in BC:

Under the first paragraph, there are seven possible impacts of sea level rise in BC.  They are:

  • More frequent and extreme high water levels in coastal areas
  • Increased erosion and flooding
  • Increased risk to coastal infrastructure, as well as increased maintenance and repair costs
  • Loss of property due to erosion
  • Loss of habitat and reduced biodiversity
  • Saltwater intrusion into coastal aquifers
  • Loss of cultural and historical sites

This is especially relevant because this year, the West Coast is predicted to face “King Tides”.  You can learn more about King Tides at the following links:

For your assignment tonight, please

  1. Choose one of the 7 possible impacts (listed above and in the main article) of rising tides that you think will have the greatest impact on our hydrosphere.
  2. Give at least two reasons for your choice, and,
  3. Describe one way we can help minimize the effects of rising tides on our coasts.

I look forward to your responses,



  1. xaxo6 04

    1 The more frequent and extreme high water levels in coastal areas. 2 I chose this because in a few decades Vancouver Island may not be as big as it is know and 2 major cities on the coast of the Island may flood as well causing more people on the mainland or in the centre of the Island. 3 The ways we can stop or slow the rising tides would be to stop our emissions thus possibly lowering the temperature in our climate. Also 80% of the rising tides are caused by carbon dioxide emissions.

  2. Amethyst

    I chose ” More frequent and extreme high water levels in coastal areas”. I chose that because when the water is already high the tides will just be really high and damage more stuff as in, habitats of animals, trees or other plants and maybe houses of people that are right in front of the water. Also I chose that because it seems more likely that having the water higher all the time could hurt the sea and land animals because sea animals will get use to having the water higher and when it gets even higher it could hurt them and land animals if the water just gets higher it could push them in to the water. We could build something along the water to block it from getting to high like a wall maybe I’m not sure what it could be made out of but it would have to be tall enough because if it is too short than the water will just go over it and be even taller/ bigger. I also thought that we could make a wall probably made out of gravel, and build it out in the water like 10ft in to block the deeper parts because there wouldn’t be any waves if the rest of the ocean is blocked off, but also so people can still swim.

    • dickensdiv16

      Yes, Amethyst, you’re right, the environment is also a habitat for people, plants and animals! I like your thinking about trying to contain the ocean to keep it at its regular boundaries, but do you think this would create hardship for animals that live along the shores?

      • Amethyst

        Actually now that you say that I kind of think that they could affect the animals. They could make a little hole because the animals can go back and forth also the hole won’t be big enough for waves or anything to damage something.

  3. Rouge

    I chose “Saltwater intrusion into coastal aquifers”. I think that the king tides affecting and breaking apart the aquifers will be very bad, because aquifers hold loads of clean healthy water that we drink and use. Aquifers are our main source of ground water and we can rely on the water to drink and to keep the environment clean and “green” with fresh water. If this happens salt water would mix with the fresh water which prevents humans and animals from drinking the now partially salty water and from watering the plants and soil with fresh water. I chose this because when the saltwater mixes with the fresh water aquifers it will decrease our amount of fresh groundwater for our water supply and the environments supply which affects us and everything around us enormously. Also the saltwater will mess up the layers underground which may result in ground damage or changing whats above, which could affect our homes and daily transportation. I think that to prevent rising tides getting into our communities we could build temporary walls around the ocean (while the high tides in winter are going on) and have sandbags around important landmarks and hospitals to prevent the water getting into our city.

    • xaxo6 04

      I like how you chose to talk about aquifers. I just have a question might you have to replace the walls around the city and how do you get in and out of the city?

      • Rouge

        I might have to replace the walls, but instead I think that I could build another layer around the wall to keep the water contained. I think that the walls would be around the ocean and not the city (sorry if I said that in my original post)

    • dickensdiv16

      Really thoughtful response, Rouge! I like how you connected to the presentation about Fracking – thinking about the earth as a layer cake. You’re right, having saltwater in the aquifers could be a serious issue for the soil, and for all living things that use soil for nutrients or a habitat.

  4. Crazychicken lover

    #1 I think salt water intrusion into aquafer is very important because it is one of the main sources of water we have and without it could effect alot of biodiversity.If that happens, we will lose alot of water that we have and that is not good because than we would probably have alot more issues coming up like borrowing water from the mainland provinces and than we would waste alot of the water that we have.It would affect the hydrosphere in a big way because aqaufers are what goes into big rivers and lakes which affect the watersheds and affect the diffrent cycles of water and carbon which affect the hydrosphere. If that ever happend and we werent ready we would be in alot of trouble. There are a lot of solutions to these problems. We could create more laws on protecting aquafers and make a large dike like the ones they have in the netherlands. Or we could make a limit on how much water that we use and store it in big,protected containers of water so that when disaster strikes we can be prepared for the worst.

    • dickensdiv16

      Crazychicken lover, you’re right – those aquifers are essential for our drinking water. It’s also true what you say about needing to be prepared for a disaster. I think our connectedness to both the oceans and fresh water puts us in a spot where we need to consider protecting groundwater more than most places!

  5. super cheese cake

    I choose Loss of habitat and reduced biodiversity because those animals could extinct and we can never see them again that’s bad. Well somebody think that’s fine but that’s actually not, they died because of us and some of us aren’t even sorry about that!! What we can do is to continue to make effort to decrease the factors which cause climate change. We can also observe those animals’ habitats and behaviors, then move them to a safer and suitable place.By doing these we can minimize the damage.

    • dickensdiv16

      You’re right, super cheese cake, extinction is serious and permanent. Relocating vulnerable animals is certainly one way of addressing the problem, but what about animals that migrate? That might be more challenging!

  6. crazymemeslol123

    #1 I chose increased erosion and flooding.#2 Because 1 flooding a can cause serious damage to humans and animals we humans have to build new house same as animals but animals will take a long to to rebuild their nests or there dens depending on what type of animal and 2 it’s because we humans can sometimes cause erosions because we use a lot of fossil fuels it will damage the climate cycle causing more Corbin dioxide it means taking down more trees.#3 I think we should stop building more boats because it might be the thing that’s causing king tides and our currents to grow stronger.

    • dickensdiv16

      Yes, all of our houses, animal and human, are chosen for very good reasons and it is hard for us to adjust to new environments. Thanks for connecting our learning about the carbon cycle to this question!

  7. Shadow145

    #1 I choose Loss of habitat and reduced biodiversity because animals can die and become extinct and we may never see them again in our lives like the dodos, passenger pigeon, the sea cow and the great auk and the other types of animals who became extinct the last thousands of years. If animals become extinct year by year by getting hunted or loss of habitats what would we even do if this happens even we can become extinct if every animal on the earth went extinct. all we can do now is relocating animals into safe environments and decreasing climate change so animals wont die.

  8. smeagaleater10

    I chose loss of property due to erosion because if a big flood gets into the dirt and makes it moist, houses will fall, the ocean will become more polluted, and British Columbia will become a wasteland. To minimize the almost undeniable damage, we need to raise or create walls near the coast so that way ,hopefully, there will not be as severe destruction of property.

  9. the DUDE

    I chose loss of habitat and biodiversity. I think this will have the most impact because if you take away the habitat then the animals have no place to live. On their new journey to somewhere else, basically most of them die. To minimize the impact of rising water levels, we could build big stone walls that separate the ocean from the city. We could also try to push any new development further away from the water’s edge. There was a thing that started in the 1500’s called dikes – my stone wall idea is a lot like that. Dikes also protect land from rising water levels.

  10. den10@sea43

    I choose Loss of habitat and reduced biodiversity.

    I think loss of habitat is a big one because animals have a big part of the carbon cycle and others and if they die it releases more carbon into the air and that is definitely a big one there. Also animals dying can affect us and other animals that rely on that animal. Like how I studied tigers and how they are endangered. there are a lot of big problems with animals dying and it is not good

  11. The Baconator

    I know that this is a horrific issue that people think will only happen in dreams. The thought of people losing their homes to something that can be solved is really terrifying and sad that we will just be adding to the homeless and that is why I chose this issue, because we still have time to solve it!!!
    To stop this or at least minimize the consciences I would make a speech and whoever wanted to save the country could help. We would go around door knocking and tell people what was going to happen and we would tell them to try to not pollute. We could also keep a look on all the rivers, lakes and of course the close by ocean. A big part of this is air pollution because gas goes up and gets stuck in clouds and when it rains that gas eventually leads to the ocean or a major water shed so we wold limit the use of gas and fuel
    I really hope we find a solution soon.

  12. Arctic owl

    I chose loss of habitat and reduced biodiversity .
    Because , think how many animals live in the ocean this will create a large impact on them . Also its not just animals that have a habitat humans have have habitats to and the ocean will have a effect on them, to think after a kings tide how many homes and buildings will be destroyed .
    I think a way to minimize damage is to see which beach’s it effects most a build a wall separating the beach from the town or city and so people can get down there in the summer put some stairs there and just block them up when the kings tide comes

  13. balloongirl123

    1 I think salt water is an amazing thing about is how fresh it is so humans and have food and of courses fishes because if fishes don’t have fresh water then can maybe die from how bad the water is. It is just like the beach how it effects on how dirty it is because in the beach people would throw garbage in the water and more other bad things could happen in the beach.


    I choose increased erosion and flooding because:
    #1 Coastal flooding could cause debris to get into the watershed and through the water system. The negative effect is that it will make water systems contaminated. That would infect freshwater life because tiny debris could throw off the cycles. For example, if a salmon was trying to find its way to spawn, it might not know where to spawn. It also affects algae, microscopic life, plants, birds and other riverside and lakeside dwelling animals.
    #2 Flooding can cause property damage. Housing is very expensive in Vancouver and to get a house sort of means you don’t have a lot money for other things unless you are very rich. This means that not many people have insurance for their houses so if they end up losing their house due to flooding then it will be really hard to find a new place to live.
    -One way we could minimize the impact of erosion and coastal city flooding is to reduce global warming so the sea levels don’t rise because of melting polar ice caps. (And there are so many ways to reduce global warming: buying less plastic-using products, using less oil, doing less fracking–so many human activities.) Also we could plant more trees and stop deforestation because when a tree is cut down, it makes the soil more loose and causes erosion. Also trees help reduce global warming which makes it so the polar ice caps don’t melt as much and cause flooding.
    It is all connected so much it blows my mind!

  15. Joaquin

    I chose loss of habitat and reduced biodiversity because i think that animals are very important to the environment because if a lot of of animals die then a lot of carbon is released into the air which is not good. Also if the animal is almost extinct or if it is a rare species and it dies that is not good because they will be lost to humanity. If deforestation happens that releases carbon into the air which is not good. In all the areas that flood the most, they could make a stream that leads to a deep pond which can hold a lot of water. This could be an idea to help reduce the amount of flooding that happens every year.

  16. iron lanturn

    I picked” salt water intrusion into costal aquifers”

    are aquifers are very important to the water cycle and the environment so to have that water become salty. it will effect are lives because it will make most lakes and rivers in British columbia salty so people wouldn’t swim in those lakes and which means local residents would move away so that lake would be forgotten and would probably be paved over [rivers are different]
    and rivers on the other hand would be evan more effected because animals rely on fresh water to live so they would die.
    and that river would run into a lake probably so that would be salty to. but in one case salty water would be goodish?
    because fracking company wouldn’t get that water.
    to stop this we could put barriers by the shore stop the salt water from getting to the aquifers. sort of like a a bored walk by the sea
    it would go under ground a bit to so that water wouldn’t get underground at all.

  17. Sr.Fruitcake

    #1 loss of Habitat and reduced Biodiversity #2 I think that that would be the most important possible out come because in learning about the hydrosphere is that biodiversity can help all issues that effect us. Also if we don’t have as many animals we lose a huge part of our eco-system and the carbon cycle in which animals take in carbon balancing the amount of carbon. #3 I expect that many people gave this as an answer but reducing our emissions would really help because part of the reason why the waters are warmer is our emissions. That feels like the most important thing to me and if we work toward that we can find more specific things to do.

  18. baconguy

    I think that the problem that would effect the coast the most would be “loss of property due to erosion” because unlike animals we can’t rebuild our houses ourselves. It would cost millions of dollars to rebuild or buy a new house. The other problem is that you have to find a house before buying one and that can be tough. We can help minimize the tides by burning less fossil fuels and doing a lot less fracking because those commit to climate change and bring high tides.

  19. Ginger

    I think that “loss of habitat and reduced biodiversity” would have a very big impact on our hydrosphere. Rising tides will significantly affect beach dunes, lagoons, and everything that lives in or on them. When most people think of dunes, they think of barren, uninhabitable landscapes in the middle of the desert, but actually, they are nesting grounds for many birds and create the perfect climate for many special plants to grow. If tides rise, there is a possibility that these birds and plants could become endangered or even extinct. Lagoons are also a very important part of the hydrosphere and biodiversity; many animals, such as Pacific Grey Whales, migrate for months to give birth to their calves in lagoons. If tides rise enough to overflow the banks of a lagoon, whales would not have a safe place to give birth and predators would be more likely to capture the calves. I think that a law should be created which only allows the manufacturing of electric boats. This would help the hydrosphere by decreasing the fossil fuel emissions into the atmosphere. Boats which run on fossil fuel produce emissions which leave an oily residue on the surface of the water can be harmful to any marine surface feeders. Older boats that run on gas would still be allowed but would be encouraged to transition to boats with electric motors in order to save the environment and animals.

  20. DancingPorcupine

    I chose ‘ Loss of habitat and decreased biodiversity ‘. I think that this will have an impact on the hydrosphere because you need animals to keep the cycles going and if they don’t have a safe habitat or any habitat at all they would either have to find a safe space which would mean that every species of animal would all just be in one place and there would not be very much variety or, they would die because they would not be able to keep warm. I think that this is a very important issue because it is something that if it goes to long without being helped could lead to extinction. It also affects farmers because if animals dont have habitats that they can make shelter in they will go to places where that is provided for them like barns or in fields with large crops such as corn or wheat. We can help this problem by trying to not use cars as much because if we are driving too much the gas from our cars could pollute the air which could make it hard for some animals to live in places that are above ground like in trees.

  21. Soccerboy123ABC

    o chose More frequent and extreme high water levels in coastal areas chose that because in some places there allready is hi tides so if the tides go higher it can cause serious destruction like in less of habitat for people and animals.also if the tides get higher and stronger the tides might beach animals like whales and other animals but it could also take animals from of the shore line and into the water and if they were land animals it might kill them depending on how far they were thrown out to the water . i think that if we make a wall that starts a little ways out then make bigger and bigger walls behind it so that we can catch the waves when they are further out so that they wont be as big but if it makes it over a wall there will always be a bigger wall behind the wall the wave got over.


    I chose ‘ More frequent and extreme high water levels in coastal areas ‘ . I think that is will have a huge impact on our hydrosphere because this could lead to flooding. The ocean tides are all ready really high and having them be come higher could lead to even larger problems like people losing there homes due to inner and outer destruction. What we can do is to start building farther away from the water so when the wave comes it wont damage as much.

  23. cooperraine

    Loss of cultural and historical sites

    i choose this because history is a really big part of everyones life because someday we all with be history and people will look back on us like we look back on people like Albert Einstein and picasso
