Question

Harmful algal blooms (HABs) result in the overgrowth of microalgae that produce neurotoxins that affect humans. What human impact will likely increase the appearance of these HABs? O Industrialization has led to increased carbon emissions and global climate change Air travel has increased the movement of people across the globe O Large-scale agriculture has provided food to more people from fewer sources Advances in medicine have kept people alive longer but in a susceptible state Large-scale deforestation has increased the interaction of humans with animals and pests

Answer 1

Dense algal blooms drew large amounts of carbon dioxide from the atmosphere and the water bodies they were in.  As a result, rising atmospheric carbon dioxide is expected to favor an increase in harmful algal blooms.

The rise in carbon dioxide is due to rapid industrialization.

So the answer is A.
