Our gut feeling is that all these packagings are very bad for the ecosystem. But the content of what you buy has a much greater negative impact. Packaging of vegetables contributes to roughly one tenth of the total impact. In the case of animal products, this is up to less than 1%. If the packaging protects the content, it makes a positive environmental contribution. Do throw the packaging in the trash, because plastic ís a problem in nature.

This indeed makes the biggest difference! From the agricultural surface whereof one carnivore can live, 3 to 7 vegetarians or 12 to 20 vegans can be fed. Much more efficient! In addition, a cow emits methane: a 23 times more powerful greenhouse gas than CO2. Also, there is 15,000 litres of water hidden in 1 kilo of beef.

Hidden Impact

We as Western consumers have much more impact than we think. Not only in our daily activities in and around the house or weekly at the gaspump, but mostly on the other side of the world, by producing and transporting the things we buy and use daily. We as consumers ultimately pay for that hidden impact and we keep the system in position. This book gives you background information and practical tips, so you can have a positive influence.
