Cultural Tip
In German environmental discourse, "verändern" is slightly more formal than "ändern" and often appears in scientific reports or news articles. The reflexive form (sich verändern) emphasizes that the change happens to the ecosystem itself, not because someone is actively changing it. Avoid using colloquial shortcuts like "Ökosysteme ändern sich" in formal writing, unless you want a more conversational tone.
