The world's oceans, should ocean protected area exist - Essay Example Marine resources are so much important for the humans as â€Å"97 % of all the water on the Earth is in the oceans† (Yang) and because â€Å"71% of Earth’s surface† (Woods Hole Oceanographic) is covered by oceans. Stabilizing climate temperatures, exchanging of climate gases, and increasing biodiversity are parts of benefits that the ocean yields us. Similarly, ocean produces half of the oxygen that the humans breathe and offers a great environmental condition that keeps organisms alive and growing.

This paper critically analyses same sex marriage and tries to answer the question; â€Å"Should same sex marriage be legalized or not† â€Å"A benefit to heterosexual society of gay marriage is the fact that the commitment of a marriage means the participants are discouraged from promiscuous sex† (Bidstrup).
