It is not possible for people to live and prosper without affecting their surroundings. However, people do have the ability to consider the needs of other species and can choose to modify their activities to decrease the negative effects they have on wildlife habitat.

Biodiversity and migratory birds in crisis


Smithsonian Migratory Bird Center

Quote:
Instinct and the annual increase of daylight hours have long been thought to be the triggers for birds to begin their spring migration. Scientists at the Smithsonian Conservation Biology Institute, however, have found that that may not be the case. Researchers have focused on how warming trends in temperate breeding areas disrupt the sensitive ecology of migratory birds.
This new research shows that changes in rainfall on the tropical wintering grounds could be equally disruptive. The team's findings are published in scientific journal Proceedings of the Royal Society B, today, March 30.
