What activities of humans have negative effects on the subsystem hydrosphere?

Inadvertent and deliberate discharge of petroleum, improper sewage disposal, and thermal pollution also are seriously affecting the quality of the hydrosphere. The present discussion focuses on three major problems—eutrophication, acid rain, and the buildup of the so-called greenhouse gases.

How can humans reduce their negative impact on the environment?

Use public transport, cycle or walk instead of using a car. Use facilities and trips run by local people whenever possible. Don’t be tempted to touch wildlife and disturb habitats whether on land, at the coast or under water. Be careful what you choose to bring home as a holiday souvenir.
