Answer: BOTH
i think climate change is a lil bit of both a man-made problem and a natural occurrence here why we as people don't care how we treat our environment or our lands ,oceans and animals we only care about things if it beneficial to us!! but our actions lead to climate change like us throwing stuff an trash anywhere us producing more trash in the ocean companies putting chemicals in the air so therefore; its like case and effect. The Cause is littering and polluting the earth. the Effect is the earth fighting back and leading to it changing to adapt to our ways which leads to us all being in harms way
