 We live on a shrinking planet! There's no need for measurements. World populations continue to grow and put ever-increasing demands on natural re?sources. Every day cities are expanding their borders and infringing on sur?rounding farmlands and forests. Every day plants and animals are becoming extinct(灭绝的) as a result of the expansion of our modern society. The con?servation efforts of governments may be able to preserve many forests and public lands for future generations to enjoy but they can't stop the lines wait?ing to get into these places from getting unbearably long. Camping requires uncrowded open spaces in order to be appreciated. As a result,the opportuni?ties for memorable camping experiences are getting fewer.

  What are the better reasons to go camping to enjoy the outdoors and the scenic wonders of nature while we still can? With popular outdoor destinations requiring reservations as much as a year in advance,the feeling of the outdoors is getting lost in the crowds. More and more it's becoming necessary to camp in the off season or to travel great distances in order to find any peace or stay alone.

  There are many valid reasons for escaping the daily activities of ordinary life and camping helps that escape for many of us. We all need a return to na?ture now and then. We all can benefit with a break from our daily activities. The thought of sitting around a campfire under a clear sky,staring up at the stars,and listening to the sounds of the night can strengthen our bodies,calm our minds,and restore our spirits. Camping is renewing！

  Search for your youth and go camping！ And,wherever you find peace,stop for a moment and reflect on how blessed you are to be able to sense this mar?velous planet we call Campground Earth. Remember to share your love for the outdoors with family and friends and to help pass on some respect for nature to future generations.

  Cold weather can be hard on pets,just like it can be hard on people. Sometimes owners forget that their pets are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time,thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your ani?mal warm and safe.

  Keep your pets inside as much as you can when the weather is bad. If you have to take them out,stay outside with them. When you're cold enough to go inside,they probably are too. If you must leave them outside for a long time,make sure they have a warm,solid shelter against the wind,thick bedding,and plenty of non-frozen water.

  If left alone outside,dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors,and provide them with shelter of good quality. Keep an eye on your pet's water. Sometimes owners don't realize that a water bowl has frozen and their pet can't get anything to drink. Animals that don't have clean and unfrozen water may drink dirty water outside,which may contain something unhealthy for them.
