One is drift netting. These nets are indiscriminate and also catch, injure and kill fishes that are not intended to be caught. This, therefore, greatly affects the marine ecosystem. 

Second is over-fishing. This reduces the fish population to a point where they are unable to regenerate and hence predisposes/ condemning them to extinction   

Third is the destruction of marine ecosystem, deliberately, to clear an obstacle or pave the way for fishing lines. This damages the habits hence affecting the ecosystem from primary producers and up the food chain.

How is the blending theory of inheritance useful in genetics?
makkiz [27]

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

Blending inheritance is an outmoded biological theory from the nineteenth century. According to the theory, children inherit any characteristic as the average of their parents' values for that characteristic.

As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.
