One of the major issues in reducing the production of greenhouse gases is the ability to produce and use alternative fuels such as hydrogen, methane or ethanol. Compare and contrast these options with special regard for how they may be biologically produced.
In the light of carbon cycle:
a) How we humans disturbed the carbon cycle?
b) What can we do so that these disturbances are not cause and they don’t affect the environment? Suggest at least three ways.
Based on what you know about ozone thinning, which location would be the most concerning in terms
of exposure to UV radiation, assuming you were planning to travel there?

- The concentration of carbon dioxide has been rising in the Earth’s atmosphere at an unprecedented rate. Explain why this increase is happening in terms of chemical reactions and emissions sources. Identify two ecosystem consequences of this enrichment. Describe some ways the problem can be addressed.arrow_forwardWhy does the ozone layer's ability to block UV-C mean that most species likely have no protections against it?arrow_forwardChapter 10 of your textbook describes four biogeochemical cycles (some of which might also be called nutrient cycles) which carry elements and compounds essential to life on earth: the oxygen cycle, the carbon cycle, the nitrogen cycle and the phosphorous cycle. Read the sections in the textbook and refer to the diagrams for each of the cycles.These cycles are constantly going on around us. Think about how we are involved in these cycles. What parts of the major biogeochemical cycles do we witness or experience in our daily lives? Give one example per post or response. Think about where the element or nutrient may have come from or where it may go next and whether the process may have been affected by humans and human activities.A simple example (using the hydrologic cycle, which we studied in Chapter 7): Yesterday I was at the beach and witnessed rain falling into the ocean. This is part of the hydrologic cycle. Most of the rainwater probably came from evaporation of water from the…arrow_forward
