CAN NEW TECHNOLOGY SAVE OUR ENVIRONMENT?
Tues, Sept 9,16, 23, 30, Oct 7, 2014. 10:45 AM to 12:15, RISE PowerPoint talks
I will show photos of nature’s beauty with Thoreau quotes. The forces of spiritual values coupled with knowledge of the earth sciences can hopefully lead to a new global ethic to conserve nature’s beauty for future generations.
2. Can new technology save us in time? Limits to Growth: Food Crash. The MIT-authored book, Limits to Growth, projects an economic and food-per-capita collapse. Written in 1972, predictions for the population explosion, water shortages, and non-renewable resource depletion have been accurate to date. Can we afford higher food prices?
The costs of weather extremes from floods, hurricanes, droughts, & wildfires are increasing. Rising temperatures are melting Greenland and Antarctica, and flooding coastal cities. (See Economic Risks of Climate, June 2014, http://riskybusiness.org)
The scientific evidence is that the main cause of global warming is greenhouse gas emissions coming from our burning fossil fuels.
Non-polluting electric cars now get the equivalent of 100 miles per gallon. The cost of solar PV cell electricity is now $0.08 per kWh, half what we buy from the grid. Carbon emissions tax? Northern Pass hydropower from Quebec & NIMBY. Pollution from fracking?
Paul H. Carr, BS, MIT; Ph.D., Brandeis, IEEE Fellow, taught the 2010 RISE (Rivier Institute for Senior Education) course Beauty in Science and Spirit, also the title of his book. He taught similar courses at U Mass Lowell. From 1967 to 1995, he led a branch of the AF Research Laboratory, which pioneered the development of compact SAW (Surface Acoustic Wave) filters used in cell phones, TV, and radar.
