Biologically generated meat without animals is the newest technology embraced by Bill Gates and Richard Branson. https://www.forbes.com/sites/zackfriedman/2017/08/25/why-bill-gates-richard-branson-clean-meat/2/#403830b64040 We all (or at least most people agree) we need to make drastic changes in our lifestyles in order to “save the planet”. I think in most scientists’ minds it is obvious that we are not going to leave the planet unscathed from human activities. What damage can be mitigated is the real question.
In the case of meat, I noticed as the price of it went up after the Bush Administration raised gasoline prices in the United States, slowly the cost of meat went up. Recently meat prices have leveled off or gone down. This was a result of leveling off of other prices, and also I’m sure producers changed their business models to keep their products affordable.
Globe Trekker has also recently got on the “meat is destroying the planet” topic with “The Story of Beef”. http://www.pilotguides.com/tv-shows/the-story-of/the-story-of-series-1/the-story-of-beef/
Seems that producing pastured raised, grass fed beef which is eaten in moderation is according to one interviewee the solution to the used of grain for meat production, grass helps clean the atmosphere, and the meat is its self much healthier as well. Rather that allocate large tracks of land to grain production and use all the fertilizers, tractor fuel, pesticides, etc to grow that which in turn will be eaten by beef animals, this solution is less resource dependent, and produces meat which has more nutrients and is less damaging to the environment as a whole.
We are faced with many challenges. The topic of food has, and necessarily so become political. The Globe Trekker piece did have a segment on India where obviously the cows were saved from imminent death. We are always faced with choices. Now it seems the conscious are aware that even simple choices such as food have repercussions which they never could have imagined.
We know meat has serious health and environmental repercussions. Some have indeed gone vegetarian or vegan, but some can not because it does not give them the nutrients they need. There is a push now for better beef, much as there was a push for better beer in the 1990s which resulted in the current micro-brew explosion in the United States. As beef producers reacted to the oil crisis of the 2000s, now the consumer reacts by not wishing to eat junk beef which is mass produced.
The moral of the story is that we face important choices. Human beings are prone to constantly change and adapt which shows our amazing intelligence as a species. What is not clear is that wisdom does not always equal intelligence.
