First pioneered by a company in the middle of the Pacific Ocean, this strategy may become more and more effective in eliminating the carbon dioxide excess in the atmosphere. The basic tenets of this approach are as follows.
- Plants can act as a carbon dioxide sink, also known as simply a carbon sink, meaning that they can trap carbon atoms inside themselves. As a result of this activity, the carbon dioxide content in the atmosphere will decrease.
- The plants on land, such as grasses, ferns, and trees, have already covered as much of the land as humanity will allow. Therefore, even the growing of new forests will not help much to alleviate this problem, especially in the long term.
- The plants of the sea, such as plankton and algae, still have significant room for blossoming. These can also act as a carbon sink, but because they are in the ocean they will not significantly affect humanity and this can be conducted effectively.
- The plankton have enough of every resource to blossom, but cannot because the sea is direly missing a critical chemical-Iron. This can be replendished and placed at excess through dumping iron fillings, known as seeds, into the ocean.
- When the iron enters the ocean, a blossoming of plankton will occur, leading to the consumption and capture of the carbon molecules.
This strategy is currently under investigation; however, there is no indication that there will not be side effects.
- James Lovelock, author of such books as The Ages of Gaia and Gaia: A New Lookat Life on Earth has suggested that we should be grateful to oil companies who leave disused deep sea oil platforms at sea. The iron from the rusting hulk helps feed the ocean eco-system.
