And preaching to the converted, this documentary adds nothing new to those that have preceded it. It makes the fatal mistake of inviting famous faces such as Tony Robbins and Richard Branson add their two cents worth; people generally do not enjoy being lectured about how to live by those in their ivory towers. The romanticism of native tribes in the Amazon, Mongolia and Taiwan is cringeworthy and exploitative; these people are not a plot device. The makers are seemingly out of touch with the average person at which this documentary is pitched; they do not grasp how some recoil at idea of veganism due to the holier-than-thou attitude of its adherents. They also fail to ask the single most important question: how much cheaper must plant-based options be compared to their meat versions for people to make the switch? Personally, it would be around 20%. Meat eaters are attached to the ritual and symbolism of eating meat; there has to be an monetary incentive to entice them to give that up.

Disapointing. Mainstream narrative coming from the 80's. "You people have to become vegan to save the planet". Do you really believe that if becoming vegan will save the planet, then this pseudo-documentary is for you. Otherwise skip it.

Doing a bit of research outside mainstream narrative you may find that:

• All life on earth is being dissimated mainly by contamination (soil, water, air).

• Profit based industries are mostly responsible.

• CO2 greenhouse effects has been repeated in loop so many times that everybody believe it true. Well it's false, we actually in an era of very low level of CO2. Nature, trees, plants, sea life NEED CO2 to thrive.

• Gov., Science, & Medias all have been hijacked by industries. Hell, even humans have been hijacked. It wasn't the people who raised the consumming society, it was industries with their marketing, TV, Radio, News paper... all that to gain more profit, constantly promoting the illusion of more happiness with acquiring more useless stuff.

There is never a single solution to a complex problem and the bigger picture is far more complicated than shown during this documentary. These documentaries frequently concentrate too much on surface issues rather than looking at root causes of the issues we face today. Our economy, economic norms of growth and over consumption and over population are the root causes, yet these aren't really addressed.

It also oversimplifies the switch to a vegan diet as many switching still rely on processed food. Many meat substitutes have high quantities of fat and salt - what impact will that have on health and well-being? How about other ingredients such as palm oil? We also have intensively farmed fruit and vegetables, as well as rising numbers of GM crops, linked to biodiversity loss due to increasing use fertilisers and pesticides - yes, some of this is also associated with the meat industry but what are we going to do about our current vegetable and fruit growing practices alongside decreasing meat consumption? What impact is the alternative milk industry having e.g. Almond growing in California? It all needs to be thought through properly. Plus, a minor point, deforestation is also more complicated. For example, in Scotland there are numerous factors over thousands of years including climate induced deforestation, agriculture clearance, deliberate destruction to reduce resources of competing communities, housing, the industrial revolution and war.

It's an opportunity lost, as it could have delved deeper, given there are already numerous documentaries saying exactly the same things this one does.
