Coconut can be a good source of fats to be used as a biodiesel feedstock, while the rest of its pulp is still edible, so it could be used more effectively to overcome the competition between biofuels and food production for arable land and water resources. It's also possible to extract sugar from coconut palms, like it's done in Indonesia.

Of course, all the cow feces in the world isn't probably as bad as one day of car exhaust from a city like New York or Los Angeles. It's all relative.

Cow poop only produces methane when it is stockpiled and stored under anaerobic conditions, such as in a feedlot. Cow poop deposited in a healthy pasture is quickly buried by dung beetles where it is turned into more dung beetles.

And dung beetle poop! Though in my experience (grew up around dairy farms) cow poop in a pasture can last for months. And longer in open range grazing in the west.

The problem with rice milk, and with rice in general, is that the plant bioaccumulates any heavy metals found in the soil (such as cadmium and arsenic) in the grain. Try to buy rice that wasn't grown in soils contaminated with the past use of arsenic based pesticides or by nearby metal smelters.

Cows have been pooping (and belching and farting) for millions of years, and they were not causing climate change then, and they are not, now. The cycle of life is a closed system, for all intents and purposes, and so no energy or material can be created or destroyed - so plants grow, and animals eat the plants, and the whole cycle stays stable over the long run.
It is factory farming that is the problem - we use natural gas to make artificial fertilizer - this is the source of the added carbon, that is contributing to warming the climate. The nitrogen in this fertilizer ends up as nitrous oxide - which is MUCH more powerful GHG than methane.
Cows (and other large herbivores) could actually save the planet, by sinking carbon into the soil.

Dung beetle poop is a perfectly healthy additive to a pasture and is delivered right to the plant's root zone. I said "healthy pasture", overuse of many of the wormers used to control parasitic worms in livestock has killed off the dung beetle populations in many pastures. A thriving dung beetle population can bury a fresh cow pie in 4 hours. The dung beetles on my farm bury cow, sheep, and chicken manure within a couple of days.

With humor like yours, this world does not merit saving.

Yes, they do. They produce lots of methane. It was actually recently discovered that seaweed reduces this. So hope is not lost.

"Experiments in sheep showed that if dried Asparagopsis taxiformis seaweed made up just 2 percent of total feed, methane emissions drop by 70 percent."
"Seaweed experiments in Canada were inspired by observations that seaside cattle, who periodically chowed down on storm-tossed seaweed, were both heftier and healthier than their inland relatives."
"Scientists calculate that it would take some 6,000 hectares (about 15,000 acres) of seaweed farms to supply a mere 10 percent of Australia’s 29 million cattle; to supply America’s 92 million would take over thirty times more."
Some articles say 99%, but that was in cow simulations, compared to the experiments with live sheep.
