kerrys wear boots said:yeah. but massive amounts of sea algae isnt exactly the best thing for the planet either. if theres an overabundance, light cant reach plants that live under the surface, and that just totally throws off the food chain.
3 acres isnt much by itself, but in the united states alone, estimates say as many as 35 million beef cattle are slaughtered. thats a shit load of land.
I think you misunderstand slightly - massive amounts of sea algae are great, currently existing, and have existed for the past several hundred million years. 2/3rds of the earths surface is water - and all of that is inhabited by photosynthetic algae and other marine plants. The algae does not block the sunlight because different pigmentations absorb different light wavelengths. Surface algae will absorb a specific spectrum, whereas deep-water flora will absorb the wavelengths that are able to penetrate that far below the ocean's surface. The food chain of the ocean is pretty stable, there's not a whole lot of habitat destruction or other things like what occurs on land except in specific instances.
It's just something a lot of people don't think about. For one, photosynthesis on land isn't horribly threatened to the point of extreme concern. Sure we cut down trees and destroy plants, but there are tons of them. Also, if plant life were evenly distributed (which it's not) then think of it this way. 66% of the world's photosynthesizing plant life is not being touched. Bring into account that algae can grow through ocean space (upwards, from surface to floor) and you get a lot more surface area in the ocean than the land.
Bottom line is photosynthesis/oxygen isn't a problem.
