Answer:
The harvest of algae allows them to be used for food and medicine production, as they are a source of proteins, vitamins and minerals. In addition, this harvest reduces the risks of the process called "red tide", which occurs when the algae population becomes so large in the aquatic environment, that it ends up throwing toxic elements on it, which negatively affects marine life.
The downside of harvesting algae is that harvesting can be done in a way that drastically reduces the population of algae in the aquatic environment and harms animals that have algae as their main food source. In addition, algae are responsible for much of the oxygen in the atmosphere, when harvesting it aggressively, it can impair the concentration of oxygen in the atmosphere. To avoid these problems, it is necessary to harvest the algae in a conscious and sustainable way.
Step-by-step explanation:
Algae can be described as eukaryotic, autotrophic organisms that can be unicellular or multicellular, present in most rivers and oceans. Despite being very similar to plants, algae are not considered plants, but a totally different and intriguing organism. The algae make photosynthesis and are largely responsible for the oxygen available for our breathing.
