In this final post, you will be applying what you have learned in the class to the real world. Choose an article involving chemistry published within the last six months. Explain how a chemistry topic you learned in this course can be used to understand the chemistry behind this article. Be sure to cite your source in APA citation.

BIO 1302 UNIT 5 JOURNAL Instructions Watch the following video segment titled "Humans: Destroyers of Ecosystems": New Atlantis (Producer). (2002). The sixth extinction: The human role [Video file]. Retrieved from https://libraryresources.columbiasouthern.edu/logi... Click here for a transcript of this video segment. How much time did you spend outside as a child/teenager? Describe your experiences with forestland or other natural environments. Are those areas still in their natural state? Even if you have not spent much time outdoors, have you seen natural areas become fragmented due to land-use change (housing developments, industry, clear-cutting, etc.)? Consider the benefits and services provided by natural lands (clean water, air, biodiversity, etc.). How does the loss of forests and other natural lands affect you personally? Give specific examples. Your journal entry must be at least 200 words. No references or citations are necessary.
