En-en adult card 1 human activities
Card #1: Human activities
This is where it all begins...
This is where it all begins... It is also where 5th IPCC report begins. In the foreword of the report, it is stated that "the IPCC is now 95 percent certain that human beings are the main cause of current global warming".
This card can be considered:
- either as the cause of all the economic sector cards (Industry, Building Usage, Transportation, Agriculture),
- or as a heading for these cards (in which case they can be grouped together and circled).
- Industry accounts for 40% of greenhouse gas (GHG) emissions
- Building usage accounts for 20% of GHG emissions
- Transportation accounts for 15% of GHG emissions
- Agriculture accounts for 25% of GHGs if we include induced deforestation.
- Fossil Fuels One can wonder whether human activities use fossil fuels or fossil fuels enable human activities. Do not waste time on this debate and put these two cards together if necessary. When I sing in my garden, I carry out a human activity without fossil fuels. When windmills or water mills produced flour, they did not use fossil fuels. Luckily, there are still many human activities that do not use fossil fuels.
- Armed Conflicts This is the Club of Rome feedback loop! The system will eventually regulate itself, but not necessarily gently. Players often make this connection and sometimes even suggest rolling up the collage to connect the beginning and the end. Moreover it is interesting notice that humankind appears in the first and last cards, but not in the middle.
- Deforestation Deforestation can be considered either as a human activity, or as a consequence of agriculture, or both.
- Terrestrial Biodiversity Humans occupy almost all available space on Earth, leaving no room for animals and plants. This entails the disappearance of natural habitats and it is the main cause of biodiversity loss today, well ahead of climate change.
- Marine Biodiversity With this link, we highlight all the degradations that humans are inflicting on marine life such as plastic pollution and overfishing. It's irrelevant to climate change, but it's interesting to make the connection anyway.
