5. Human Activities and Global Warming
Objective: Understand Causes, Effects and Solutions of Global Warming
Key Words: concentration, biodiversity, fossil fuels, deforestation, industrialization
Human Activities and Global Warming
Humans had first affected global warming some eight thousand years ago with the start of agriculture. Due to the clearing of the forests for agriculture, the amount of carbon dioxide in the atmosphere increased drastically.
Since the industrial revolution, humankind also contributes to the increase of carbon dioxide by the burning of fossil fuels (coal, oil, gas, petrol) to obtain energy. For instance, carbon dioxide is released by power plants, factories, and cars.
List at least 2 human activities that increase the amount of CO2 in the atmosphere.
Agriculture: deforestation, burning the forest
Industrialization: Burning fossil fuels (oil, natural gas, coal) in power plants, factories, cars, etc.

7. The Effects of Global Warming
Objective: Understand Causes, Effects and Solutions of Global Warming
Key Words: concentration, biodiversity, fossil fuels, deforestation, industrialization
The Effects of Global Warming
Increasing global temperatures is melting the ice cap and rising the sea levels, which will cause the flooding of coastal areas. Also global warming is changing the climate: it has changed the amount and patterns of precipitation, and increased the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, hurricanes and tornadoes.
Other effects of global warming include loss of biodiversity, endanger and extinction of species, and migration of species. For instance, diseases like malaria are returning into areas where they have been extinguished earlier.

Objective: Understand Causes, Effects and Solutions of Global Warming
Key Words: concentration, biodiversity, fossil fuels, deforestation, industrialization
Global Warming Solutions
We have the practical solutions at hand to dramatically reduce our carbon emissions and slow the pace of global warming.
Reduce CO2 emissions.
We must significantly reduce the amount of carbon dioxide emissions we are putting into the atmosphere.
Expand the use of renewable energy and transform our energy system to one that is cleaner and less dependent on coal and other fossil fuels.
Increase vehicle fuel efficiency, support public transportation and car pooling.
Place limits on the amount of carbon that polluters are allowed to emit.
Build a clean energy economy by investing in efficient energy technologies, such as solar energy.
Stop Deforestation
Reducing tropical deforestation can significantly lower global warming emissions and — together with efforts to reduce emissions from fossil fuels — plays an integral role in a comprehensive long-term solution to global warming.
6. List at least 2 actions to effectively stop Global Warming?
1. Reduce the CO2 emissions to atmosphere
Reduce the use of fossil fuels
Use of clean alternative energy sources i.e. solar energy

2) State one environmental impact of reduced funding for public transportation (trains, city buses, school buses, etc.) on future generations. Explain your answer.
Reduced funding for public transportation will increase the amount of cars on the roads,
therefore, CO2 emissions to the air will increase,
then, Earth’s average temperature will increase.
In conclusion, it will contribute to Global Warming.

a) Increase the number of trees through reforestation, OR
b) Protect animals so that their numbers increase.
 Using one or more complete sentences:
For each statement, identify whether or not the action will contribute to reducing the CO2 level of the atmosphere
For each statement, explain why the action will have the effect described in part (a) on the amount of CO2 in the atmosphere..
(a) Reforestation will reduce atmospheric CO2 because plants take in CO2 from the atmosphere by photosynthesis.
(b) The increase of animal population will increase atmospheric CO2 because animals produce CO2 by cell respiration.

4. Scientists have discovered a link between deforestation and global warming. Write a paragraph that explain what is meant by the terms deforestation and global warming, then describe the connection between the two.
Deforestation is the removal of large numbers of trees from a forested area.
Global warming is the rise in Earth’s average temperature over time.
Deforestation increases global warming because CO2 remains in the air and it is not removed by photosynthesis.
Trees can use carbon dioxide during photosynthesis to make carbohydrates. The carbohydrates are used to make new cells and tissues. These tissues last for the life of the tree, keeping the carbon dioxide “stored” for a long time.
