Worms,antis,and flowers live in soil.Fish,crabs,and seaweeds live in oceans.Birds,insects,and moss live in trees.soil,oceans,and trees are habitatsplaces where animals and plants live .Besides offering food and shelter, habitats allow for growth and reproduction.     Humans, however,have destroyed many habitats.We change forests into parking lots. We turn grasslands into neighborhoods.We turn beach land into resorts.We turn 0ceans into chemical dumps.Some plants and animals adapt and survive.Others,however die.The changes are too much,too fast.Sometimes the death rate becomes greater than the birth rate.then the extinction occurs.An example of this happened on Florida's east coast,the habitat of the dusky seaside sparrow.This habitat changed suddenly as land was developed. And the sparrows were not able to adapt. More sparrows died than were born. In 1987 the  dusky seaside sparrow became extinct.None exist in the world today.     Fortunately,conservation efforts are underway.Many states have set aside land for nature preserves. Here,plants and animals live in their natural habitats.Some states have created man-made habitats .Artificial reefs,for example,have been put in ocean waters. The artificial reefs are habitats for hundreds of fish and other marine life.In 1970 the federal government passed a law to protect habitats.'Ibis~that the efforts of development must be studied.A highway,dam,or power plant may not be built if plants and animals,endangered.We were too late to save the dusky sparrow.Hopefully,however,these new efforts will save other plants and animals.
