Tools to Counteract Greenhouse Gases - Diatoms

People have paid much attention to the accumulation of greenhouse gases in our atmosphere because they play a significant role in global warming. The main culprit in the greenhouse gas list is carbon dioxide. Not only do we exhale this gas, but fires of all kinds produce it. With the recent major fires in Australia, there is even more concern about the amount of carbon dioxide in the atmosphere. But God has given the Earth some tools to counteract greenhouse gases.

The most efficient tool built into the Earth is a microscopic plant called a diatom. There are 12,000 species of diatoms in Earth’s lakes and oceans. Unlike phytoplankton, diatoms are encased in porous, intricately structured silica shells. Examined under a microscope, these silica shells are beautiful, and they are very resistant to change in shape. That means that the spaces between the shells can collect particulate material. So diatoms are used as filtering agents to filter water for swimming pools and as fillers for aerating soils in yards. The shells are used as diatomaceous earth, which is familiar to most of us, especially those who raise roses or tomatoes.

Diatoms can also absorb gases. In the oceans, they absorb massive amounts of carbon dioxide and lock it up in the ocean’s depths. Diatoms capture as much carbon dioxide as all the trees, grasses, and other land plants combined. The fancy latticework of the diatom is not just for humans to admire. Because of the twists and turns of their shells, the surface area of diatoms is much greater than that of smooth shells. The increased surface area maximizes photosynthesis and allows the diatoms greater energy for growth and reproduction.

The life expectancy of a diatom is about six days. Because the silicon is heavy, the diatom at death sinks to the ocean floor or lake, taking carbon with it. One solution to the buildup of carbon dioxide is to catalyze the growth of diatoms. Iron nutrients can do that, and seeding the oceans with iron might be a way to reduce the amount of carbon dioxide in the atmosphere.

Diatoms are one more example of the design built into Earth’s structure to allow the planet to exist over the long haul. While diatoms are not apparent to the human eye, they are tools to counteract greenhouse gases and a possible solution to a modern problem.

With a growing human population, environmental toxins, the warming of our planet, and the shortages of potable water, we recognize that Earth is under stress. News reports tell of people dying because of ecological problems. It is essential to understand that all of this pain, death, and turmoil are unnecessary. When God created planet Earth, He built into it many self-correcting tools for survival. If you name a major problem that threatens the long term existence of humans, I believe there is a built-in device that can correct the problem. God designed the Earth to withstand even the abuse that selfishness, ignorance, and greed have brought upon it. Here are a few examples of God’s environmental solutions:

Carbon dioxide and global warming. Several greenhouse gases contribute to global warming, but the main one is carbon dioxide. Not only do animals exhale carbon dioxide, but fires produce it, so human-caused fires are a contributor. God beautifully designed planet Earth with tools to contain carbon dioxide. Plants take it out of the air and release oxygen as a product of photosynthesis. This system is highly efficient as a single tree can take care of the carbon produced by one human. Plants in the ocean do the same thing. Human deforestation of both the land and the sea thwarts the system God put in place to sustain life on Earth. God’s environmental solutions are there if we will use them.

Water. Oceans cover roughly 3/4ths of Earth’s surface, but water shortages plague a significant percentage of the world’s population. The obvious problem is that because of minerals in the water, ocean water cannot be consumed directly by humans or most animals or plants. But the 50-quadrillion tons of minerals in the oceans, including 4.5 billion tons of uranium, have 14,000 industrial uses. God’s environmental solutions not only provide enough water for every living thing on the planet but also a wealth of minerals to sustain an advanced society.

Toxins. In the past five years, science has discovered that a Chinese brake fern (Pteris vittata) can survive on arsenic. Arsenic is a significant pollutant poisoning millions of people in the world, causing skin lesions, cancer, and other illnesses. Finding a plant that removes arsenic from the environment is a significant breakthrough. Over the past several years, we have mentioned other plants that provide environmental cleansing. Scientists have found bacteria that eat plastics and others that consume crude oil. These are more of God’s environmental solutions to tackle the plastic trash and oil spills in the ocean.

We need to allocate research funding to learn more about God’s environmental solutions to counter ecological problems. God has given us resources to repair the damage we have done to the environment. Maybe the problems we see around us will bring us to accept what God has provided and have the heart to think beyond our own selfish interests.
