Native Americans People lived in the United States long before the arrival of Christopher Columbus and the Europeans. These people and cultures are called Native Americans. Native Americans lived throughout North and South America.They were grouped into tribes or nations usually based on the area they lived in and their culture such as their religion, customs, and language. Today, some of the descendants of the original American Indians live on reservations.(These are areas of land set aside specifically for Native Americans).This helps to protect their heritage and culture.
Many wildlife habitats will be destroyed if man keeps polluting the environment. 2. If we dump all sorts of chemicals into rivers, we will not be able to swim in them in the future. 3. If we do not stop cutting down so many trees, we will endanger our oxygen supply. 4. Soon the Earth’s resources will be exhausted if the human population continues to grow. 5. If everybody continues to use aerosols and CFCs, the hole in the ozone layer will get bigger. 6. If the sun radiation can’t escape into space, Earth’s temperature will increase steadily. 7. If the global temperature rises, sea levels will rise too. 8. We’ll threaten our own existence if we do not cut down on waste rapidly. 9. People will run out of drinking water one day if they do not use it more rationally. 10. If he wants to help the planet, then he has to change his habits
