Meat and environment, is that possible?

No, if meat is responsible for the current pollution, it does not mean that we should stop eating meat.

There will always be meat (old hens, cows, etc.) because without it, we would have to produce much more fruit and vegetables to provide the protein we need.
On the other hand, it is possible to eat less meat and only meat that is produced in a much more environmentally friendly production system. Cattle, in particular, can find grass in marginal pastures (roadsides, embankments, mountains, waste, etc.) without having to gain land on agricultural and forest land (corn, wheat, etc.).
Livestock is not the result of natural selection but of human selection. Species are selected for particular conditions (disease resistance for example) but they can also be selected according to environmental criteria (a cow that metabolizes grass better and produces less CO2). 28% of animal pollution is related to the control of diseases due to their concentration.

There is a huge margin for reducing pollution (CO2 and methane) by changing production methods (breeding and animal selection). “For example, in Japan, 52% of waste from the food industry is now used as livestock feed, thanks to adequate policies and a certification system” (FAO).

CETA is a democratic crime because it allows Canada to sell products in Europe that do not respect the environment, workers and consumers. This is unfair to European workers who are bound by standards. It is up to Europe and North America to adapt and adopt a more environmentally friendly industry because, in addition, they alone account for half of the world’s pollution.
