“To recycle carbon dioxide into methane, an established industrial method involves the reaction of hydrogen and carbon dioxide using a ruthenium-based catalyst at temperatures of 300 to 400 degrees Celsius, but this method limited how much and when methane could be produced since it requires such high temperature,” …

Rotting vegetation produces methane, and in normal situations that methane would escape into the atmosphere in incremental doses. But the rotting plants behind a dam store up their methane in the mud.

Our conclusion is that methane gas is is produced fairly equally between decaying fruits and vegetables. We see that vegetables produced more than fruits within the seven days that bucket one was still usable.

Wherever there are bogs, this process happens. Old wood accumulates and is turned into peat, then lignite, then finally into coal. Methane is also generated and is either locked up into rocks or methane hydrates, and also seeps back into the atmosphere.

Wood — unlike oil, coal and natural gas — is not considered a fossil fuel. But decomposing trees do give off carbon dioxide, and so does burning firewood. As part of photosynthesis, trees take in carbon dioxide, release oxygen and produce sugars.

Scientists estimate that the black carbon produced by wood burning is the second most significant contributor to global warming. Black carbon particles in the atmosphere absorb solar heat. This not only heats the atmosphere, but also melts the earth’s snowcaps and glaciers when these particles settle on the ground.

When forests are cut down, not only does carbon absorption cease, but also the carbon stored in the trees is released into the atmosphere as CO2 if the wood is burned or even if it is left to rot after the deforestation process.

In trees, sex exists beyond the binary of female and male. Some, such as cedar, mulberry, and ash trees, are dioecious, meaning each plant is distinctly female or male. Others, such as oak, pine, and fig trees are monoecious, meaning they have male and female flowers on the same plant.

Potatoes are tubers. Potatoes have no gender. They reproduce asexually.

Blame the Males The pollen count can be lowered if people plant more female plants and fewer male plants, says horticulturist Tom Ogren. He says male plants have been popular because they don’t produce messy fruit or seed pods — but they are responsible for most of the pollen in the air.
