Nonrenewable and Renewable Resources Human Impact on the environment

Bell Ringer Write the answer to each question in a complete sentence, 1) Have you used water today (includes, showers, drinking, flushing toilets) 2) Have you eaten food that was not labeled as organic? 3) Have you used paper products? 4) Have you ridden in a car or bus? 5) Have you thrown anything in the trash? Explore: Students will have 12 cards with pictures on renewable and nonrenewable resources. Two additional cards have the names NONRENEWABLE and RENEWABLE. They will have 3 minutes to organize the cards. Teacher will walk around and see the students initial misconceptions of what a renewable and nonrenewable resource is.

If you said yes to any of these questions… YOU have negatively impacted the environment TODAY.

Why should we study Earth’s resources?? If we continue to use resources at the rate we are today, we will run out by the year 2050.

Background Knowledge Is our population growing? Yes! What is the carrying capacity of the Earth? Too difficult to determine but we don’t want to push it! Are we running out of certain resources? Coal, Oil (gasoline), Clean Water…

Ecological Footprint Definition: Amount of land necessary to produce and maintain enough food, water, shelter, energy, and waste Size depends on: amount of resource use and the amount of waste produced

When our ecological footprint increases, the biodiversity in an area decreases

When we use fossil fuels or electricity, our ecological footprint increases and adds to the greenhouse gases that contribute to global climate change

What are a few of the ways humans damage the Earth? The Green House Effect and Climate Change. Pollution of water, air and land Loss of biodiversity.

What is Climate Change As Carbon dioxide is created by humans burning fossil fuels it fills up the atmosphere and prevents heat from leaving. (hint: like a greenhouse for plants. )

The Green House Effect Over the last few years the temperature of the Earth has continued to increase. Effects: Ice caps melting, longer seasons, more drastic weather.

How does water and air pollution effect us and other organisms? Acid Rain is created by pollution. The Ozone is destroyed which is Earth’s natural protection from the Sun. Toxins in the water can spread through the food chain. Toxins can come from human activity such as farming.

Loss of biodiversity. Turtle getting onto the pavement not the ocean because of the lights clip--- we increase the amount of limiting factors on a population

An umbrella species is: A species whose protection means a wide range of other species and land will also be protected

Renewable Resource Examples: Nonrenewable Resource Examples: Draw this Renewable Resource Examples: Nonrenewable Resource Examples: 1. 2. 3. Have students COPY down table onto their left page. This will give them examples of renewable and nonrenewable before we even define them. Word Bank: Solar Energy, Fossil Fuels, Wood, Wind Power, Coal, Nuclear Energy,

Renewable Resource Examples: Nonrenewable Resource Examples: Debrief Renewable Resource Examples: Nonrenewable Resource Examples: 1. *Solar 2. *Wind 3. *Hydroelectric (water) *Wave/Tidal Biomass energy 1. *Coal 2. *Oil *Nuclear Minerals/Metals Propane Gasoline Timber/Wood Have students COPY down table onto their left page. This will give them examples of renewable and nonrenewable before we even define them.

Renewable Resource Cannot be used up or can replenish themselves overtime. Examples: Solar Energy Wind Energy Hydroelectricity What does this mean?!! Wave/Tidal NOTES Examples are already in student’s table.

Renewable Resource Impacts: Might disrupt ecosystems Recyclable “Clean” Minimal if any CO2 emissions NOTES

Awesome Energy Stats! Enough sunlight falls on the Earth each minute to provide the world energy for an entire year. If 10,000 schools turned off their lights for one minute, it could save $81,885. If you fart consistently for 6 years and 9 months, enough gas is produced to create the energy of an atomic bomb!

Are there any negative impacts from Renewable Resources? Renewable structures may disrupt ecosystems BIG wind turbines Solar panels only work during the day Wave/tidal only works where there is a constant supply of big waves CFU

Nonrenewable Resource Resource that is used faster than they form. Fossil Fuel: formed from dead animals/plant material over millions of years. Examples: oil, coal NOTES Because they take millions of years to form and we use them over a daily basis. Examples are already in TABLE.

Ways in which humans can protect the environment Control population growth Develop technology to produce more food and less waste Change current practices Maintain ecosystems Use renewable resources

Three important environmental laws Clean Air Act Clean Water Act Endangered Species Act

Sustainable Development The practice in which resources are used and managed in a way that meets current needs without hurting future generations

Sustainable practices in the fishing industry: Rotation of areas that are being fished Reviewing fishing gear Fishing bans/laws Harvest reduction

Checks For Understanding Why are fossil fuels called fossil fuels? Why are fossil fuels nonrenewable? Imagine burning fossil fuels (coal, oil). What impacts do you think it has on the environment? Can you think of any positive to burning fossil fuels? Because fossil fuels are REALLY OLD and made FROM FOSSILS. Dah Disrupts ecosystems, pollutes environment, not sustainable, etc. They are typically HIGH QUALITY.
