Offtopic > The emissions from travel it took to report this story were 0kg CO2. The digital emissions from this story are an estimated 1.2g to 3.6g CO2 per page view. Isn't 1.2g per page view huge amount? I wonder if we can have api for this.

Some envelope math. From https://www.eia.gov/tools/faqs/faq.php?id=74&t=11 , I get .99 pounds of CO2 per kWh. That converts to 449 grams. Splitting the difference between 1.2g and 3.6g, we get 2.4g. 2.4/449= 0.00534 or ~0.53% of 1 kWh consumed, or 5.3 watt-hours. Which does strike me as rather high.

The page took 20s to load for me. That's about 1kW to get the ~5Wh. That seems reasonable. Just my internet equipment consumes about 50W, and there are many servers involved in loading a BBC page.

According to Website Carbon Calculator, each page view produces 2.22g of CO₂. I think it would be lower if you use an ad blocker.

Loaded in well under 2 secs for me (no JS, all ads blocked, not that there will be on the bbc)

What about the impact to birds insects and animals that access the canal for water?

Looks like they could fit through the gaps in the side. I doubt it would take them too long to find that, especially if they knew where the canal was

Makes me wonder just how much power/carbon waste goes in to ads vs content on the modern web.

These are V-notch canals, made of cement and carry fast moving water. Not many creatures will try swimming or drinking in it. There are smaller mud canals that carry water from these to the field. Insects, birds, and animals can be found there.
