What belongs here

Stay inside the room’s stated scope rather than adjacent off-topic dumps. Low-effort memes/empty shitposts are often removed—add real context.

How it differs from lookalikes

Prefer this room when your post matches its description and rule list—not merely a larger sibling community. The public rule list is long enough that skimming all entries once beats assuming defaults from similar subs.

Practical pointers

Read the live sidebar/rules before posting; rules can change. Search before reposting common clips/questions. Avoid clickbait titles.

The community was created on Jan 25, 2008, which makes it 18 years old. Since Nov 2, 2026, it has gained 301 subscribers (+0.02%). Among the 11 communities on our environment and climate list it is the largest. It sits just behind r/cybersecurity (#678) and ahead of r/Aquariums (#680) in our ranking.
