rivers and run- off from farmers fields bring extra nutrients into a lake allow increased growth of algae in the water. The result is a population explosion of algae called an algal bloom
It is called an algal bloom. Algal blooms can be caused by excess nutrients in the water, such as nitrogen and phosphorus, and can result in the water changing color due to the high concentration of algae. Some algal blooms can be harmful to aquatic ecosystems and human health.
Algal blooms can be unnatural when human activities, such as excess nutrient runoff from agriculture or sewage discharge, contribute to their rapid growth. This can disrupt the balance of the ecosystem, leading to excessive algae that can harm aquatic life and water quality.
Red tide is a common name for a phenomenon also known as an algal bloom (large concentrations of aquatic microorganisms) , an event in which estuarine, marine, or fresh water algae accumulate rapidly in the water column and results in discoloration of the surface water. It is usually found in coastal areas.
Algal blooms can produce toxins that are harmful to humans when ingested through contaminated water or seafood. These toxins can cause a range of health issues, including skin irritation, respiratory problems, and gastrointestinal symptoms. Additionally, some algal blooms can deplete oxygen levels in water, leading to fish kills and other ecological impacts that can indirectly affect human health.
The things that people do are human activity. The things that people cause to happen are also human activity. These acts and deeds have an impact on the environment and can cause emissions of green-house gases.
Currently there is no known connection between human activity and tornado formation and intensity.
Excess growth of algae in water, known as an algal bloom, can be caused by nutrient pollution (such as phosphorus and nitrogen), warm temperatures, sunlight exposure, and calm water conditions that allow algae to grow rapidly. Human activities like agriculture runoff, untreated sewage discharges, and fertilizer use can contribute to nutrient pollution in water bodies, leading to algal blooms.
Human activity and pollution will probably be the greatest cause of elephant extinction.
No, eutrophication can occur naturally as a result of excessive nutrients entering a body of water. However, human activities such as agriculture, urban runoff, and sewage disposal can accelerate the process and lead to harmful algal blooms and oxygen depletion.
Algal blooms can have negative effects on the environment by depleting oxygen in the water, which can harm aquatic organisms like fish. They can also release toxins that can contaminate water and harm both aquatic life and human health. Additionally, as the algae die and decompose, they can contribute to an increase in nutrient levels in the water, leading to further ecological imbalances.

cause of endangered of an animals is due to human activity in our ecosystem. Examples of that is illegal logging that can distract to the habitat of some animals that can cause to their endangerment.Hunting is also one of the activity of a human that can cause to the extinction of animals esp. in a wildlife. They kill animals for the following reason:for the skin that can be make a leather,for its meat and for their livelihood in order to suffice their needs in their lifes
