Sustainability and Global awarenessBy María Fernanda Kuntzy Pablo Olvera Pablo Zorrilla

Page 2: History PBL

Objective

- Understand and remark the negative effects on the environment consequent from the Industrial Revolution.

- Be able to understand the impact of the Industrial Revolution in our current world.

Page 3: History PBL

Driving Question:How are we trying to revert the negative effects that impacted the environment since the industrialization?

Page 4: History PBL

How it began...As industrialization expanded, pollution grew as well. Steam boats, steam trains, and factories generated more waste than there was before.

Page 5: History PBL

How it expanded..Entrepreneurs wanted to grow. To accomplish this, they seeked for new markets, land, and people looking for work. As cities grew, the landmarks began to expand to the countryside.

Page 6: History PBL

New inventions = more pollution

Many of the largest polluters come from the chemical, pesticide, oil refining, petrochemical, metal smelting, iron and steel, and food processing industries. Production rate increased due to improvements in invention. But this has the negative impact of more pollutants being disposed into the environment.

Page 7: History PBL

The full impact of the Industrial Revolution would not begin to be realized until about 100 years later in the 1800s. The environment was affected in many aspects:-climate-ozone layer- global warming-wildlife-pollution-people’s health problems

First impacts on the environment

Page 8: History PBL

Climate behaviorsNatural control of atmospheric CO2 ended at the time of the Industrial Revolution, when humans began burning fossil carbon fuels, manufacturing cement, and removing forests at an increasing rate.

- The use of coal as energy source released most of CO2. - From the late 1700’s to the year 1896, carbon dioxide had increased 30%.- Poisonous emissions = eliminating source of oxygen- Starts global warming - Greenhouse effect

Page 9: History PBL
Page 10: History PBL

Global warming

- It’s defined as the rise of global temperature due to greenhouse gases.

- This causes a rise in sea levels and a change in the amount of pattern of precipitation.

Page 11: History PBL

Carbon dioxide also escapes to the atmosphere during the process of cement manufacture and of deforestation.

Page 12: History PBL

Ozone Layer:The ozone layer protects the earth from the suns UV Rays. Ozone layer depletion, is simply the wearing out (reduction) of the amount of ozone in the stratosphere.There is a hole in the ozone layer created by chemical processes.

Page 13: History PBL

Most aerosols also damage the ozone layer

Page 14: History PBL

Pollution...

Water pollution: We are running out of water. There is so much dirty water out there that there is no way it can be cleaned. Oceans are full of trash, there is even a spot in the ocean, bigger than the size of Texas, full of trash.Air pollution: The ozone layer is getting destroyed.

Page 15: History PBL

People’s health problems:These effects have contributed to people’s health problems and obesity.

-Obesity = chemicals in food (artificial)- breathing not clean air leads to lung damage.

Page 16: History PBL

Awareness begins….

People began to see how bad this was getting.The ozone layer was getting destroyed.Water problems were occurring in many places.Climate change was affecting in a big way.When all of this was noticed, awareness began.

Page 17: History PBL

Campaigns:

Private companies and political parties have a lot of campaigns showing their concern about this topic. It is so important right now, that helping the environment is helpful for your image.

Page 18: History PBL

Perspective change

A huge change has occurred. It went from not caring at all, to being a huge worry.Little kids are the most aware of this. Now wasting water, throwing trash on the street, cutting of trees and many other things are seen as such a bad thing.

Page 19: History PBL

RRR...

Reduce, Reuse and Recycle. These three “R’s” have become such a big thing during the last years. People try to follow this three simple things to help the environment

Page 20: History PBL

Water saving

- Turning off the shower when applying shampoo.

- use a bucket and not a hose to clean the car.

- use dirty water to water the plants.

Page 21: History PBL

Regulations

- Permits to cut off trees.- Not allowing older cars

(which pollute more) to be around all days.

- Special places to build factories.

Page 22: History PBL

Inventions -Electric Cars

Electric cars, that work by charging them with electricity do not use gasoline anymore, which makes these friendlier with the environment.

Page 23: History PBL

Ecologic Urinals

This urinals have a special system in which the urine goes without the need of water every single time. Millions of liters of water are saved every year because of this.

Page 24: History PBL

Windmills + Solar Panels

Windmills and Solar Panels are two innovative ways of producing electricity.They do not create any waste that damages the environment, such as burning coal.

Page 25: History PBL

Today….As of today, all big cities are extremely polluted. But it is also big cities that are making the bigger changes to become greener and friendlier with the environment.

Page 26: History PBL

These are two examples of today’s awareness, reflecting the need that people have, to revert the damage created in the Industrial Revolution:

Page 27: History PBL

Example 1Steam boats and steam trains.Both of those inventions, that at the time were so amazing, they were also so harmful to the environment; those were two main transportations methods.Now, cars are a main transportation method, and electric cars are being created to revert the harm made in the past.

Page 28: History PBL

This means that new transportation methods are being invented based on environmental awareness with the intention of stopping the harm towards it.

Page 29: History PBL

Example 2

When industrialization began, Europe went to Africa and they exploited the continent completely, stealing their natural resources. Right now, natural resources are not that vast in most places, so really special permits are needed in order to do so.

Page 30: History PBL

Through people’s awareness about non-renewable resources, actions are being taken to stop the exploitation of them.

Page 31: History PBL

Results

All of the campaigns, big companies, and governments, have made huge impacts in people. Everyone is now more careful and people are creating new, and environmentally friendlier products.

Page 32: History PBL

Conclusion:

Industrialization was such a breaking point in history. Many inventions were made, and many things were created. Because of all of this, industrialization is often seen as an amazing point in history.But...

Page 33: History PBL

There are also bad things. People did not care about long term problems, they were so focused in the present and short term results. Almost 300 years later, we are trying to revert something that is impossible to do.
