Unit 2: Chemistry and Our Earth - Affecting the environment .D

Scenario / The editor of the local paper has asked you, as the chemist responsible for the environmental impact of the company for whom you work, to respond to an alarmist article written by an environmental group.

Assignment Task 1

You work for a large company that extracts resources from the Earth in order to make useful chemical products.

You have been asked to write an article for the local paper that presents a balanced view of the likely environmental impact of your company’s activities and how this can be reduced.

The title of your article is going to be ‘How to save the Earth’.

In your article you need to:

  • Describe how different human and natural activities have affected the Earth and its environment, the land, air and sea. For the natural activities, you also need to discuss how the atmosphere of the Earth has changed over the last two hundred million years. Use at least two human activities and two natural activities.
  • For the activities that you have chosen above, discuss which has had the greater impact on the Earth and its environment – human or natural activities.
  • Discuss how humans have tried to remedy the effects on the Earth of the two human activities you chose by carrying out alternative activities, for example recycling waste instead of using landfill.
  • What has been the effect of these ‘alternative activities’ on the environment – has it made it better or worse for the environment?
  • Identify three possible solutions to the damaging effects on the Earth and its environment from human activities and natural events.

Explain and discuss the advantages and disadvantages of each possible solution to the damaging effects on the Earth and its environment from human activities and natural events. Give your conclusion as to which is the best solution and why.

Your work will be finished if you have an article on the impact of natural and human activities on the Earth and its environment. It should include diagrams and cover approximately two pages.

2D.D5 / Evaluate possible solutions to changes in the environment, occurring from natural or human activity
2D.M7 / Discuss the extent to which human activity has changed the environment, in comparison to natural activity
2D.P8 / Describe the human activities that affect the Earth and its environment
2D.P9 / Describe natural factors that have changed the surface and atmosphere of the Earth
