Losing wild habitats is very serious. Animals (and plants) need to have a place where they can live safely. Their habitat should have food, places to build homes and raise young. Humans need to use a lot of land. We clear land for farms and for building our homes and communities. Everyone needs a place to live. If we clear a forest or grassland, we always affect the wild animals that live there. If there is another wild place nearby, they will move there, but more often than not, they have no habitat to which they can move and that population of animals dies out. This is a very serious threat for animals that have limited habitat. If there is no other population of that species, they can go extinct.
The human race is growing. There are more than 6 billion of us on Earth! Over time, more habitats are destroyed to feed and house us. Even when we save small wild places between our towns and cities, these fragmented habitats often can't support populations of animals. Many animals will die out.
People have begun to save wild lands between communities to save the wildlife that live there. They will even clean up a place that was once developed and bring back the forest. These are being called wildways (greenways). They are trying to connect and stretch them from Canada to Mexico so animals can still migrate north and south the way they once did. Migrating birds and mammals need safe places to rest, eat and travel through all year round. Wildways may heal some fragmented habitats.
Support Greenways! Find out if your town or community is working to develop a greenway and join in.
