Did you know that there is a plant that eats millions of fish and leaves whole lakes deoxygenated and without life? 00:00:05
The water fern that is entering the area is not a very well-known plant, but it normally lives in South America. 00:00:11
But in the past few years, it has extended here, in Spain. 00:00:18
You could pass through a lake and not even notice the water ferns. 00:00:22
That's because they are too small, not even more than 5 mm. 00:00:25
But in less than a year, the whole lake would be covered. 00:00:28
The problem with the water trend is that when the air pollutes, which happens very fast, 00:00:32
it creates a dense mud over the lake that pollutes the water. 00:00:35
As you can see in the satellite images, during the last month and the first month, 00:00:39
the aphidia increases because it's cold outside and they die. 00:00:44
Throughout the summer and the end of spring, they increase because they make the photosynthesis faster. 00:00:49
That would be a problem, but not as severe as what happens next, 00:00:56
as it completely blocks the lake from the land. 00:00:59
Oxygen and other useful elements can come in contact with the water, plants and animals. 00:01:02
So, the fauna of the lake has two options, they either find a way to migrate and survive 00:01:07
or they die because of a lack of oxygen. 00:01:12
Today we made an experiment to analyze the damage that adiaphericula causes in the environment 00:01:15
and try possible solutions. 00:01:20
We will study a very possible solution that consists in the introduction of a parasite 00:01:22
parasite that is caused in open-roof businesses from North America that has been very successful. 00:01:26
First week, we took four samples of Lemna NINOR and we divided them into different tuppers. 00:01:32
Besides, we measured the initial pH, CO2 and nitrate levels. During the next few weeks, 00:01:37
we measured the different parameters to see the evolution of the water quality. Besides, 00:01:45
we also took photos to see the recollection. The first week, these were the results, 00:01:49
all very normal but the second one all the variables increases which confirm us that the 00:01:55
water is very low very much apart from these numbers another thing appeared 00:02:01
more commonly known as fresnel they are common in waters with high levels of nitrates and phosphorus 00:02:09
and they have the ability to clean waters by feeding on organic detritus which can help 00:02:16
regulate the levels of nutrients in the aquariums. 00:02:20
With this experiment, we have seen how the water fern pollutes and affects the lake. 00:02:24
With the appearance of the red snake, we finally came up with a solution. 00:02:27
A combination of these, which will lead to a better maintenance of the water fern while the reproduction. 00:02:31
But that's not all, we will use this Azolla as an ecological fertilizer, 00:02:37
renewable source of energy, food for dogs, 00:02:41
and with the collaboration of some worldwide companies that work in this area, 00:02:44
will give a second chance to Antoia. 00:02:48
