In a 2017 Reddit post, 'March For Our Lives' gun control activist David Hogg celebrates the fact that mosquitoes kill "billions" of people as being "great for the environment".

Another user on the site asked the question, "What is a positive reason for mosquitoes to exist?" to which Hogg responded, "They kill humans, billions of them, which is great for the environment." The post was made eight months ago.

Although the entry was posted under the pseudonym 'davisgreen111', the account almost certainly belongs to Hogg. The poster refers to himself as "David Hogg" in one post and another post links to a video from Hogg's personal YouTube channel. Another post confirms that he lives in Parkland, Florida.
