How to spot the toxic algae that’s killing dogs in the Southeast

(CNN)Dog owners in the Southeast are spreading the word about the dangers of contaminated water following the deaths of their beloved pets. Algae occurs naturally in water, but the blue-green variety are considered Harmful Algal Blooms (HABs). Blue-green algae, also known as cyanobacteria, are “primitive,” photosynthetic organisms that can feed off the sun to make their own energy and release oxygen and possibly toxins in the process, said David G. Schmale III, a professor at Virginia Tech. Some species produce potent toxins that can sicken or even kill people, pets and wildlife, according to the US Environmental Protection Agency.

Allergy sufferers from Tokyo to London are struggling as pollen levels surge in cities, possibly due to a preference for male trees In 2016, Melbourne experienced a rare and extreme case of thunderstorm asthma that led to ten deaths and 8,500 people being abundant allergenic pollen.

This all-male council in Texas just voted to ban abortion
