Human Destruction Stats. largest estuary in the U.S. receives wastes from point and non-point sources. receives drainage from 9 large rivers and 141 stream and lakes in parts of 6 states. Phosphate and Nitrate have risen sharply in many parts of the bay. human activity has heavily affected 41% of the world's oceans.

Students learn about three examples of human impacts on marine life: migration patterns and shipping, algal blooms and water chemistry, and marine debris. Some of these impacts are due to human activity in the ocean, and some impacts on the ocean are due to human activity on land.

All these threats contribute to marine systems being affected by human activities EXCEPT: a. costal development. b. swimming in certain bodies of water. c. invasive species. d. runoff of nonpoint source. b. swimming in certain bodies of water.

Negative Human Effects Habitat Destruction Virtually all Ocean habitats have been affected in some way via drilling or mining, dredging for aggregates for concrete and other building materials, destructive anchoring, removal of corals and land “reclamation”.

“Although Antarctica is still the most pristine environment on Earth, its marine ecosystems are being degraded through the introduction of alien species, pollution, overfishing, and a mix of other human activities,” said team member Dr Sven Thatje of the University of Southampton’s School of Ocean and Earth Science (SOES) based at the UK’s National Oceanography Centre.

In terms of human activities, this essay analyzes the different kinds of actions made by human, such as adding polluting materials to oceans and human-induced changes in atmosphere and soil. Firstly, human activity in the sea has a generally negative effect on marine life. These activities can produce visible contaminations on the ocean, which might cause poisoning of marine population and a reduction in biotic productivity.

They have been introduced, either deliberately or accidentally, by human activities. Often they thrive in their new ecosystems, surviving and reproducing better than native species.
