- Requires phosphorus as a fertilizer which is becoming scarce.
What are the harmful effects of algae?
Exposure to high levels of blue-green algae and their toxins can cause diarrhea, nausea or vomiting; skin, eye or throat irritation; and allergic reactions or breathing difficulties. Pet and livestock illness/deaths can happen if animals consume large amounts of water containing blooms, scums or benthic mats.

Why is algae a problem?
Elevated nutrient levels and algal blooms can also cause problems in drinking water in communities nearby and upstream from dead zones. Harmful algal blooms release toxins that contaminate drinking water, causing illnesses for animals and humans.

What are some disadvantages of biofuel?
Disadvantages of Biofuels 1. High Cost of Production. Even with all the benefits associated with biofuels, they are quite expensive to produce in the current market. As of now, the interest and capital investment being put into biofuel production is fairly low, but it can match hepfive-jp.somee.comted Reading Time: 6 mins.
Are algae biofuels a realistic alternative to petroleum?
The short answer is yes, but algae’s long-term viability depends on prices at the gas pump. As petroleum prices remain high and the algae oil cultivation, extraction and refining process becomes less costly, algae presents an increasingly viable alternative to oil as a fuel base.
