   Scientists say a huge percentage of bird species are in danger because their habitats，or homelands，are disappearing.Traditional migration paths take birds through countries that are mot protecting locations to stop.rest and feed，The scientists studied the migration，or fight，paths，of almost 1.500 species.They decided that 91 percent of then passed through dangerous areas.
     The major danger for migratory birds is development.Building and paving have covered over nature where birds stop and feed as they move from one part of the world to another，F(xiàn)or example，a bird called the bar- tailed godwit migrates from its breeding grounds in the Arctic.It flies all the way to the southern hemisphere in Australia and New Zealand，Along the way.the small binds stop at Yellow Sean mudflats in China.Korea .
      One of the scientists working on the study Says"many of these critical sites have been lost to land reclamation（開墾）owing to urban，industrial and agricultural expansion." The problem，according to investigators，is that many of these small birds die along their migration because they don't have a safe place to eat and rest.There is no place to restore their energy for the next leg of their journey."They simply perish（死亡）along the way，"says one of the scientists Countries in North Africa，Central Asia and those along the coasts of East Asia are having the most difficult time conserving land ，The scientists say these countries do not have enough areas that are safe for birds.
   The researchers say countries need to work together and provide safe stopover areas for birds that pass through their boundaries.For example，one country might have preserved safe zones for migrating birds.But a neighbor country might not.A bird might perish.One scientist tells the Los Angeles Times that while some habitats are changing，more work can be done to make urban areas safe for birds.He says small changes-like planting more native plants or keeping cats out of areas birds would be likely to use-could make a big difference.

   With travel and the environment in the news so much lately，you've probably heard the word ecotourism.As travelers become more aware of their effect on the planet and want to do their part to make a difference，ecotourism has really taken off.
   What is ecotourism？The definition isn't as hard to determine as you might think.According to the International Ecotourism Society，it is defined as "responsible travel to natural areas that protects the environment and sustains the well-being of the local people." To be simple，it's travel that has a positive effect on a destination's ecology and economy.
   Ecotourism lets travelers participate in activities that benefit the environment.For example，travelers can act as citizen scientists in places around the world，including national parks and dive sites，to help do research and collect data.Meanwhile，ecotourism helps local communities to do well and become successful and strong.That can happen in a number of ways，involving some type of financial aspect，from providing jobs to supporting local businesses.
   Being a responsible traveler，you'll have a much more satisfying and rewarding experience.Instead of simply visiting tourist attractions and eating at chain restaurants，you can get completely involved in a local culture and really get to know the people who live there.It enriches your own life and opens your mind to new ideas.
   Ecotourism is an amazing way to discover the world.Nature is full of wonders everywhere.Being able to get out in a natural area that is protected and largely undeveloped offers a chance to connect with plants and animals you may never see anywhere else.Just be sure to leave it as you found it for future explorers to discover.Get your sneakers ready，pack your bags and head for nature.A big and beautiful world is waiting for you out there.______
