PLANTBI 40 Lecture Notes - Lecture 2: Durum, Ocean Acidification, Ultraviolet
Document Summary
Region of upper atmosphere containing high concentration of ozone that absorbs solar ultraviolet radiation. Misuse of plant matter gives rise to 85 % of greenhouse gases. Give 4 examples: co2: burning fossil fuels (oil, coal) from plant matter, methane: cows at grass, breakdown of plant material in landfill, carbon soot: burning wood and forests, nitrous oxide: fertilize plants. Farming leads to smog and soot production. Farm produce ammonia from fertilizer and animal waste. Measuring of reflectivity of different objects and surfaces on earth. Lower the number, more energy is absorbed. Ex) snow and ice, leaves of trees, grassland. What are 3 regions of the globe which carry out photosynthesis, and what is destroying their ability to do so: photosynthesis occurs in oceans by algae and bacteria. Rising temperature killing ocean photosynthetic organisms: boreal forests. Rising temperature lead to explosion of bark eating beetles that are killing trees: south america: amazon forest deforestation.
