Overfishing has depleted the rich harvests of fish from the oceans. As a solution, a large industry that cultivates shrimp and fish in warm coastal ponds has been developed. To make way for these ponds, mangrove
forests are cut down. Local organisms are displaced. In order for people to decide if this new fish farming
technology is a good long-term solution, they must consider
(1) the risks and costs as well as the benefits
(2) that the mangrove forests would probably die off someday anyway
(3) that food production is always more important than any other concern
(4) the number of fish produced in the first year as compared with ocean fishing

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
