The next destructive is the Stern Trawling. This is destructive due to the method of capture‚ in the sea for long periods of time. While this might seem beneficial as it can catch more fish‚ it may catch sea mammals or endangered creatures that aren’t intended for capture. It has a low accuracy of the specific creature to be

Coral reefs have existed on this planet for approximately 450 million years. They provide an extremely diverse marine ecosystem. (Bellwood and Wainwirght2002) Coral reefs are the largest natural structures in the world and occur in over 100 countries. They are the result of a remarkable relationship between coral animals and microscopic algae. The microscopic algae (zooxanthellae) coverts sunlight and carbon dioxide into oxygen (photosynthesis) and carbohydrates for the coral animals (polyps)

This is evolution of a natural part In our ecosystem‚ animals are part of it and they help to balance the ecosystem. But‚ due to the human activities‚ these animals begin to disappear from the earth. Dodo bird‚ Tasmanian tiger and Passenger pigeons are among the animals that have become extinct. Habitat destruction and animal hunting are the factors that cause the animal extinction. Recently‚ animal extinction occurs due to the habitat destruction. First‚ as the country develops rapidly nowadays

Air pollution and noise Transport by air‚ road‚ and rail is continuously increasing in response to the rising numbe reported that the number of international air passengers worldwide rose from 88 million in 1972 to 344 million in 1994.

The Effects of Sea-Level Rise on Coastal Salt Marshes and their Associated Ecosystem Services Katelyn M. Nyberg Introduction Climate Change The Intergovernmental Panel of Climate Change (IPCC) has observed an increase of 0.19 meters of global mean sea-level rise from 1901 to 2010‚ with “about 70% of the coastlines worldwide projected to experience a sea level change within ±20% of the global mean” (IPCC 2014). Dramatic increases in sea-level are produced by increasing temperatures which cause glaciers
