What you’re seeing here is a decades-old problem; the leading contributor of these blooms is excess phosphorus and nitrates from fertilizer used in large-scale agriculture that’s washed into streams as well as distributed via wind during the winter months. Through these tributary waterways, the chemicals eventually make their way into lakes. Pollutants from industrial and pharmaceutical factories are also a link; these chemicals and substances aren’t water soluble and over decades turn into what you’re seeing here. High temperatures and still air create the perfect conditions for algae to proliferate and accumulate at the surface. When temperatures increase, these blooms break out, which is unfortunately only increasing with the rise in temperatures directly correlated with climate change. It’s a serious problem, and one that is happening globally. To see more photos of this issue, please visit @ladzinski」9月2日 7時35分
