The memes of the climate

Those were examples, but as pointed out they absolutely do have an effect on climate change.

However, I can provide a couple more direct examples if you like:

• No public transit available, and neighborhoods built in such a way that the majority of residents need to travel miles to reach their place of business.
• Products being grown, packaged and sold in completely different countries. Driven by profit, meaning many companies make the same ridiculous decisions. Consumers are often given no alternatives for certain products.

They do though. Manufacturing in general has a high carbon footprint, and the overwhelming majority of plastics the containers won't be recycled so the next packaged item will have the exact same carbon footprint as the first one.
