Excess nutrients leaving factory farms into waterways in the form of animal waste leads to the overgrowth of algae and then forms algal blooms that contain dangerous levels of toxins. Ocean dead zones are expected to increase in both size and number as climate change intensifies.
Perhaps you have heard the term ocean dead zones but aren’t sure
what it means, what causes it, or how serious it is for our planet.
Keep reading to find out and learn how you can help prevent it from
getting worse.
An ocean dead zone is an area of the ocean with extremely low oxygen
levels making it uninhabitable and causing entire ecosystems to die
off. Most marine life cannot survive in an ocean dead zone and the
area is comparable to a very hot desert with little biodiversity.
Although ocean dead zones can sometimes form naturally, most of them
are caused by the effects of climate change and agricultural
practices.
These include the factory farming of live animals such as pigs, cows, and chickens; and pollution from commercial fertilizers and pesticides used to produce food for these animals, in addition to food for humans. Excess nutrients leaving factory farms into waterways in the form of animal waste leads to the overgrowth of algae and then forms algal blooms that contain dangerous levels of toxins. Ocean dead zones are expected to increase in both size and number as climate change intensifies.
Meanwhile in Canada, “the Canadian meat industry slaughtered more
than 825 million land animals for food in 2021, according to
government slaughter statistics analyzed by Animal Justice.” –

That is a lot of animal waste entering our precious waterways! This
is in addition to all the fertilizer used to grow crops such as corn
and soy that these farmed animals must eat to sustain themselves
until they are killed, and the next group of animals arrives. It’s a
vicious cycle.
