4 Pollution Dictionaries describe Pollution / Pollute / Pollutant as Impure; act of making unclean; contaminatingSubstance that pollutes; chemical or waste products defiling the air, soil, or water
5 Pollution comes in many forms. WaterLand & SoilAirWhat things do we do that pollute the water, land, and air?
6 Background Info:Water CycleAll living organisms are dependent on clean and safe water to live. Some of us need a lot, others do not need as much.Water cannot be created. It is something that exist on earth and is recycled.The Water Cycle is how the same water is used and reused on earth.
7 Water CyclePollution of the water not only hurts organisms that live in the water, but can hurt organisms that live on the land.Acid Rainchemicals mix and get into the water / air and comes back down as acid rain. The chemicals in the rain eat away at our buildings – bricks, metals, etc.
8 Water Pollution Water pollution is when… We dump trash directly or indirectly into the water, drains, and sewers – lakes, ponds, and riversPlastics and general trash hurts the organisms in the water – fish, penguins, birdsChemicals get into the fish and into the food chainChemicals and oils coat fish, birds, and other animalsImbalance of one organism on the food chain – disruption in the life cycle.
10 Class Discussion What are the effects of Water Pollution? How do I identify distinguish, and correct effects of pollution?What are the effects of pollution on plants and their habitats?What are the effects of pollution on animals and their habitats?
11 Air PollutionAir Pollution deals with unnatural and natural things in the air.Noise is a type of pollutionChemical from cars, factories, aerosol…Imbalance of certain gases that occur naturallyGreenhouse effectClimate Changes
12 Air Pollution Noise Pollution Stress on humans Frightens animals away from their habitatsScientist think there may be a link to noise pollution and well-beings of some animalsExample: dolphins and whales use sound for communication - our noise pollution disorients them
13 Ozone and the Greenhouse Background Info:The Sun, our main source of energy and heat, is gives off a lot of dangerous radioactive materials.The Earth is protected from most of these radioactive rays by our atmosphere. It is like a protective glass case.
14 OzoneWhat would happen if we punched a hole in this protective glass case?The Ozone is damaged a tiny bit by natureVolcanic eruptionsNaturally occurring chemicalsBUT – we humans are doing things to damage the ozone a lot!!!Chemicals released in the airLess Ozone, More harmful raysIt kills certain animals – food source for othersCauses diseases in us - cancer
15 GreenhouseThe Earth’s atmosphere helps to trap the sun’s heat…. enabling us to live.What if too much heat was trapped?Weather changes – too hotIce on earth meltshigher water levelsDisappearing landImbalance of natural gases that give us lifeMore carbon dioxide, more food for plants, more plantsMore pollen and allergens for us
16 GreenhouseThe chemicals, Carbon Dioxide (CO2) we release in the air through our cars, factories, and other industries causes more heat to be trapped in the Earth’s atmosphere – the Greenhouse effect
17 Class Discussion What are the effects of Air Pollution? How do I identify distinguish, and correct effects of pollution?What are the effects of pollution on plants and their habitats?What are the effects of pollution on animals and their habitats?
18 Land Pollution Trash is Ugly Trash can cause fires – air pollution Trash gets carried into our water supply – water pollutionTrash causes waste.
19 Misuse of LandWhen we farm too much or cut down too many forests, we are polluting the land.Too much farming strips the land of nutrients and soil protection (causes erosion)Main effect on the environment is that animals are now left homelessAnimals will migrate to unwanted areas and have to find new sources for food
20 Severe soil erosion in a wheat field near Washington State University. Some farmers terrace their land so gravity and “land slides” will not erode away land
21 Pollution SummaryThere are many ways to pollute the water, air, and land.Pollution is caused by many different things.Pollution hurts us all – directly and indirectlyInterferes with the food chainInterferes with organisms’ habitats
22 Conservation Conservation is one way to reduce pollution. Conservation deals with the smart use of our resources (like the smart economic decision making we learned in Social Studies)We have limited resources!We should conserve because:We want to reduce pollutionDoes every living organism deserve a safe and happy habitat?We are all dependent on each other for a happy and healthy life - food chain.The entire planet is our habitat!
23 What to Conserve? Why Recycle We can conserve our natural resources.Water - ElementsOther materials – coal, trees, etc.We can conserve energy.Making usable energy takes a lot of resources and can cause a lot of pollutionRecycling helps us to conserve
24 Conservation and Recycling Recycle paper helps use reduce the number of trees we need to make more paperTurning off lights reduce the amount of electricity you useYou save your parents moneyWe need less electricityMaking less electricity causes less natural resources to be used and less pollution
25 Conservation and Recycling Eat all your food or take only what you will eat.Less use of factories that help package your foodLess growing and hunting of plants and animals that provide us our foodConserve waterWe will need less energy to clean the water if you do not let it all go down the drain.Always make sure the water you drink is safe!Don’t drink from ponds, lakes, or rivers.Stay on the sidewalksDon’t hurt nature in parks or wildlife areasThese areas could be some other animal’s habitat!Don’t cause erosion!
