Question

Why do animals migrate ?
Which is better - recycling or reusing ? Why

Answer 1

1) Reasons to Move. Some animals travel relatively short distances to find food or more favorable living or breeding conditions.Most animals that migrate do so to find food or more livable conditions. Some animals migrate to breed. The Atlantic Salmon begins its life in a river and migrates downstream to the ocean.

More info:
Some crustaceans also migrate for breeding. In many species of crabs, the females will move into shallow coastal waters to mate and lay her eggs, then they return to deeper ocean waters

Frogs and toads often move very short distances to breeding ponds and lakes to lay their eggs. Some sea turtles, like the loggerhead, return year-after-year to the same sandy beach on which they hatched to lay their eggs.

2) Reusing is better than recyclingbecause it saves the energy that comes with having to dismantle and re-manufacture products. It also significantly reduces waste and pollution because it reduces the need for raw materials, saving both forests and water supplies.
