Greenhouse gases are part of Earth's atmosphere. Greenhouse gases maintain an average temperature of 15 °C
(59 °F) which is not too hot or too cold, allowing life to flourish. However, in the last century, human activities,
primarily from burning fossil fuels that have led to the release of carbon dioxide and other greenhouse gases into
the atmosphere, have disrupted Earth's energy balance. This has led to an increase in carbon dioxide in the
atmosphere and ocean. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades
and traps extra heat near Earth's surface, causing temperatures to rise results which leads to global warming.
The most significant gases that cause global warming via the greenhouse effect are the following:
Carbon dioxide, methane, nitrous oxide, and Hydrofluorocarbons
What are the causes?
Fossil fuels, using transportation, deforestation….
Task:
‘Increasing consumption in our world increases the production of greenhouse gases. What kind of solutions can
scientific innovations and technological development bring to this problem that threatens our world?’
In this assessment, you are expected to research greenhouse gases, their causes, and ways to reduce
greenhouse gases and their harmful effects. Select one greenhouse gas and develop the essay around the
effects of this gas. The word count for this essay is 1000 – 1500 words.
You must:
1. Define greenhouse gases.
2. State three global reasons that lead to the emission of this greenhouse gas.
3. Describe three global problems (health, economic, environmental, political, and ethical) associated with
increased emissions of this greenhouse gas.
4. State two specific ways in which scientific innovation is currently solving this problem.
5. For each of the above, state the positive and negative consequences of each solution.
6. Describe one scientific innovation or development that you think will happen in the next few years to deal
with the problems we face today.
7. Add at least two relevant images, cite them, and use them to prove your arguments.
8. List your resources.

Possible Essay Format:
Title
Paragraph 1: Definition of isotopes and radioisotopes.
Paragraph 2: Explain the reason why the isotope you have selected is used and describe how it is used
to solve this issue.
Paragraph 3: The benefits and the disadvantages of this specific radioisotope in medicine.
Paragraph 4: Relation to one of these global factors – environmental/ethical/financial
Paragraph 5: Based on what you have described above, what is your opinion of using this specific
radioisotope in medicine? Would you recommend it to the Scientific community? Why yes or why not?
Bibliography: Use APA 7 format.
