As great as it is to preserve and regenerate plants on the mainland, we also have to be concerned with aquatic plants as well. These are the plants that grow in seawater and freshwater. Since people don’t normally see these plants, they forget how vital they are to the various aquatic ecosystems of the world. These aquatic plants provide food and nutrients to the fish that lives in the water. This in turn creates a living food source for the much bigger predatory fish, like sharks. As you can see, the whole food supply chain of the lakes, rivers and oceans of the world depend on aquatic plants for their overall survival.
It should be no secret that water pollution in the ocean has gone rampant over the last few decades, especially with the oil spills and garage in the ocean. In fact there is a giant garbage patch in the Pacific Ocean that is the size of Texas. This is killing a lot of the sea life and especially the aquatic life. Without plants to eat, the existing fish will end up eating plastic from the garbage and that will kill them right away. Now the problem of water pollution will be one that is tough to fix. However, this doesn’t mean we can’t preserve and regenerate new aquatic plants through the use of micropropagation. If people were to create their own aquariums to raise fish for food or just for show, then tissue culture can produce the aquatic plants that would go in these aquariums. Then the fish you put in the aquarium would be able to survive outside of their natural habitat. Tissue cultured aquarium plants can typically be purchased in most pet stores around the world. The most common tissue cultured plants are the Bacopa, Cryptocoryne, Cardinal, Dwarf Hairgrass, Telanthera and Staurogyne.
As for the ocean plant life, no one knows what the future holds for it. We do know that tissue culture has the power to genetically modify aquatic plants to be resistant to conditions of drought. This will be beneficial to freshwater plants, since they experience these conditions the most. Then they can be saved and possible transported to other freshwater areas that don’t have drought. But most of all, more plants like this can be produced through tissue culture which will sustain all aquatic life. Furthermore, these plants can be modified to provide more micro and macro nutrients to the fish. This will increase their lifespan and possibly make them grow bigger in the process.
