Why would you compare a factory to an individual? That doesn't even make sense. Why not compare that Pepsi plastic bottling factory to a Brazilian beef operation that is repeatedly burning down rainforest, farming beef and soy to feed beef on the cleared land, and then moving on in a few years because the soil gets depleted?
The Cerrado biome, covering 20 percent of Brazil, has seen rapid deforestation in the 21st century; a recent report says that much of this is driven by soy grown to feed livestock, which feeds Brazilians.

As I already pointed out, the global impact of agriculture is enormous and it disproportionately comes from meat, especially beef:
Data on GHG emissions from the food system are mostly scattered across sectors and remain unavailable in many countries. EDGAR-FOOD, a globally consistent food emission database, brings together emissions from food-related land use and land-use change, production, processing, distribution...

In 2015, food-system emissions amounted to 18 Gt CO2 equivalent per year globally, representing 34% of total GHG emissions. The largest contribution came from agriculture and land use/land-use change activities (71%), with the remaining were from supply chain activities: retail, transport, consumption, fuel production, waste management, industrial processes and packaging.
Estimates of agricultural emissions are usually too low because they don’t include these five sources of greenhouse gases.

The Worldwatch Institute included agriculture’s supply chain as well, and it concluded that livestock agriculture is responsible for
51 percent of anthropogenic greenhouse gas emissions.
WWI’s estimate was
dismissed by some in agriculture, but a detailed
assessment this year found it more right than wrong. That assessment argued for an agricultural contribution of about 37 percent of anthropogenic GHGs. Stanford physicist Steven Chu also
argued recently for a higher assessment of agriculture’s contribution, in the neighborhood of 30 percent.
