Sit SILENTLY, remain silent, and copy the following questions in your notes. Answer these questions in your notes while the video is playing.

How have we as humans contributed to the warming of the earth?

What innovations or technology have we come up with to try and reduce the effects of pollution added to the atmosphere?

Do you think Charlotte has the same pollution problems as other large cities?

How Human Activities affect the Environment

We live in a bubble

The earth is a single self contained environment that we have a responsibility to keep clean.

This means we need to slow down our use of natural resources and keep our renewable resources clean and reusable.

Wait, what are resources?

Natural Resources

Materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.

Basically, anything found in the Earth that we use in products or use to make products or to produce energy.

Renewable resources

Those resources that can be used over and over again because they are cleaned and recycled naturally Water Sunlight Wind The air we breathe

Nonrenewable resources

Those resources that are used at a far greater speed than they are produced

Fossil fuels Products made from fossil fuels Nuclear Energy Some renewable resources can become

nonrenewable

What are fossil fuels?

Oil, gas, and coal Easy to use and contain a lot of energy They can affect the environment in many

ways

Pollution

Definitionadding harmful substances or products into the environment

The use of FOSSIL FUELS are the biggest cause of pollution

There are multiple types of pollution.

Make a graphic organizer

On a blank sheet of paper, draw a “t” dividing the paper into 4 sections

At the top of each section, put one of the following groups Water, Pollution, and Waste Water pollution Air Pollution Reduce, reuse, and recycle

Take notes under each section for each video segment Devote each square on the graphic organizer to two

We will start with air pollution.

Air Pollution

Pollutants (such as burning fossil fuels) released into the atmosphere can have harmful effects. Smog Depletion of the ozone layer Creation of acid rain

Some causes of air pollution- Car emissions factories

Air Pollution

Effects on the environment can include Health risks to living organisms All air pollutants return to the ground in some

form which effects the surrounding landscape

Air Pollution - Example

Air Pollution - Example

Air Pollution- Effects of acid rain

Air Pollution-Ozone depletion

Water pollution

We will move to Water pollution next

Water Pollution

When pollutants are added to the water supply Oil spills Fertilizers (chemicals)

Water Pollution

When a water supply is contaminated, not only are aquatic plants and animals affected, but also any organism that needs that water to survive

The next 2 Videos describe what happens to the waste we produce at home

Reduce, reuse, recycle Water, pollution, waste, skip to 3:33

Land Pollution

Humans produce hundreds of millions of solid waste each year…..

Where does it go?

To a landfill!

Human Development/Population

Today there is about 7 billion people on the Earth

By 2050 (when you guys are in your 50s) the predicted population is expected to be around 9 billion people

Go back to the website on your phones and answer the following question. Do you think that our technology can prevent

environmental collapse, or will our planet be too far from saving by 2050?

What if…….

An ecosystem of forests was destroyed and replaced with a large shopping mall?

Predict how this will most likely affect the environment of the area. Result in habitat destruction Decrease in animal population Increase pollution

What if……

As a city’s population grows, wooded areas are replaced by housing developments.

What effect will this most likely have on the species in the wooded areas? Many of the species will leave the area Some may die if there is no other habitat

available

Pollution

Pollution- adding harmful substances or products into the environment

The use of fossil fuels is the major cause of pollution

Exit Ticket

What are the major contributing factors to pollution on our planet today?

What is the difference between a renewable resource and a nonrenewable one?

Give some examples of how we could help to relieve the strain on the environment caused by human pollution practices.
