Trawling is a fishing practice in which a large net is withdrawn in a water body. Two or more boats are pull the net lying horizontally under water. This practice helps in catching various diversity of aquatic species. It is done on the surface, mid level and bottom levels.

It is destructive to fish habitat because of the following reasons:

1. It introduce non-native species to the habitat which leads to decline in population of native species as non-native species can be invasive.

2. Some unwanted animals also get trapped in the net which are latter discarded.

3. Some undersized fishes are discarded. This will lead to decline in future fish population.

4. Bottom trawling uses heavy nets which draggs over the seafloor as a result of this everything in the path of the seafloor get disturbed like aquatic plants, coral reefs and rocks.

b. climate change will cause an increase in biodiversity of all ecosystems.
