Summary Of Plan B 4.0 By Lester R Brown

Good Essays
The book Plan B 4.0 by Lester R Brown revolves around the transition to a fossil fuel-independent society, the efforts currently in place or in plan, and the effect it will have on Earth and our lives; or, in other words, ditching our current lifestyles for a “plan b” way of life. The main message of the book is that our current society and living situations are beyond unsustainable and we all need to work towards further correcting that. Brown presents various lifestyle changes we must make and various ways the government can pave the way in order to improve the overall health of our planet and the wellness of people currently affected by the horrid condition our environment is in. First, Brown describes the role we have had in depleting our…show more content…
You see, as our planet heats up, the water on and in it evaporates and this causes a drought. Evaporated water also happens to be one of the miniscule greenhouse gases. The water does eventually come down but it does not rain in the areas where the water was taken, leaving that area dry. Furthermore, the water on Earth’s surface absorbs the Sun’s heat, thus when there is little to no water to absorb the heat, the Earth continues to heat up. Brown proposes we work towards stabilizing our climate by making energy efficient the norm, electrifying our transport system, and converting to renewable energy as oppose to coal. He also suggests that we, as a society, must put effort towards transforming our cities to make them more inclusive, eliminating the chances of poverty and stabilizing our population, repairing the damage we’ve done to our planet, and feeding all the people already on our planet. Personally, I felt moved by the efforts, worried for our future, & startled by the facts presented. I was particularly concerned about the fact that a big chunk of the earth’s greenhouse gases is coming from cows, which are our main source of…show more content…
The excess of greenhouse gases in our atmosphere have led to a dramatic rise in the climate and the hottest recorded years the Earth has seen. To be specific, “the 25 warmest years on record have come since 1980 [and] the 10 warmest since global recordkeeping began in 1880 have come since 1996, (p 56)” which is nothing to boast about, seeing as this is also the largest population and most technology the Earth has ever seen. Moreover, in lecture, we went over the amount of greenhouse gases created solely by livestock and how being a society dependent of livestock for food is very negative. Livestock emit about 68% of all agriculturally produced methane(lecture) and methane counts for approximately 18% of greenhouse gases (p 57). That is not to say that livestock do not create a large amount; in fact, human-caused methane emissions are almost solely from agriculture. To combat this, Dr. Wailes proposed that instead of basing our diet on water-heavy crops and methane-emitting animals, we switch to much more sustainable foods. One example of this would be to eat bugs. Bugs contain much more protein by the pound and do not eat alfalfa, which is what causes cows and other livestock to emit greenhouse gases into our atmosphere. Dr. Wailes also displayed a chart with three different “meals” which
