When the explorers first arrived in the continent of North America， the skies and lands were alive with an amazing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately， it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources.
Millions of waterfowl （水禽） were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations， greatly reducing waterfowl habitat.
In 1934， with the passage of the Migratory Bird Hunting Stamp Act （Act）， an increasingly concerned nation took firm action to stop the destruction of migratory waterfowl and the wetlands so crucial to their survival. Under this Act， all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp （联邦鸭票）. Hunters willingly pay the stamp price to ensure the survival of our natural resources.
About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System—a fact that ensures this land will be protected and available for all generations to come. Since 1934， better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever started.

Pollution is a problem all over the world. But it is especially bad in large cities with a lot of industries and cars. 1
Wildfires， volcanoes， and industrial chemicals cause some air pollution. But most air pollution comes from burning fossil fuels. The burning of fossil fuels may release harmful gases. It leads to polluted rain that can harm living things. 2 Finally， air pollution damages the ozone layer （臭氧层）， which is important because it protects earth against harmful rays from the sun.
