Greenhouses and Submarines

Without a means to replenish oxygen (O2), a submarine crew would soon suffocate to death. How does this relate to greenhouses? Both are closed environments. Laboratories in a box, so to speak.

Growing plants in the closed environment of a greenhouse depletes the carbon-dioxide (CO2) essential to sustaining plant life. Growers introduce CO2 to replenish this vital gas which has been consumed by the plants in the greenhouses and to elevate the concentration to a minimum of 1,000 parts-per-million (ppm) to accelerate plant growth.

For most greenhouse crops, increasing the concentration from to 1,000 ppm will increase the photosynthesis by about 50% over ambient CO2 levels.

Carbon-Dioxide is a natural gas, not man-made. It is the basic building block of all life on earth.

According to the National Oceanic and Atmospheric Administration, ” Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.”

Still earlier in Earth’s history, there were vast forests on Antarctica.

A scant 1,000 years ago, Vikings grew corn and barley in Greenland due to a receding ice sheet.

In the video below, Dr. Patrick Moore, one of the founders and now a former member of the Greenpeace environmentalist movement, discusses the dearth of carbon.

Environmental activism, climate-change activism, has become a belief system, a religion. The genesis of the environmental movement was science-based and sought to protect threatened species and the vital qualities of air and water. The religion of environmentalism focuses on the harmful effects of mankind, mankind as the enemy of the earth.

As Dr. Moore points out, wealthy contemporary climate-change alarmists like Al Gore and Leonardo DiCaprio hypocritically denounce the use of carbon-based fuels and processes while they themselves leave enormous ‘carbon footprints’ from use of large private jets and ocean-going yachts.

Carbon-dioxide is a plant nutrient, an actual plant-life fertilizer. As Dr. Moore states, we need more of it in our atmosphere to sustain life on earth.

The natural liberty of man is to be free from any superior power on Earth, and not to be under the will or legislative authority of man, but only to have the law of nature for his rule.

A lifetime (over 50 years) of experiences with automation and control systems ranging from aerospace navigation, radar, and ordinance delivery systems to the world's first robotic drilling machine for the oil patch, to process-control systems, energy management systems and general problem-solving. At present, my focus is on self-funding HVAC retrofit projects and indoor air quality with a view to preventing infections from airborne pathogens.
