global trends in agriculture the environment and food
DESCRIPTION
This presentation won't make you feel good when you read it, but it should motivate. The 4th slide shows "The Great Acceleration." Since the mid-19th Century every trend line flies upward, both positive and negative. One should read the words of the Founder of the Baha'i Faith who lived and taught at that time and see what He said about the needs of the future. Slides 5-8 relate to consumerism. One slide shows a bird bringing more material goods to its overloaded nest but doesn't notice the branch is cracking. Slides 9-14 show water issues, and the red in the Middle East is said by many to be related to the Arab spring. Slides 15-34 should be read by all who will be alive in 2050 and think that life will stay the same. Slide 58 talks about the dark force creating our world.TRANSCRIPT

from a growing population we will
need to produce more food in the
next 40 years than has been
produced in the previous 8,000
years.
