Ethical travellers hoping to minimise their impact on the environment and give something back to the communities they visit may want to consider booking Ethiopian Airlines flights to Africa.
This year, Earth Day falls on April 22nd and it will see people all around the world unite to try and reduce the damage being done to the planet.
Jet-setters who hope to make a contribution in the places they travel to may find that heading to the highlands of Ethiopia provides them with a holiday to remember.
The Lonely Planet claims the destination offers "tremendous trekking" and the chance to see and interact with animals that cannot be found elsewhere.
In a piece for the National, Nick Leech noted that some walking holidays in the area enable hikers to give money to local villagers, who take them into their homes and act as guides.
He asserted that "a truly ethical holiday is one where you give something back to the area you visit".
The more ambitious climbers who head to Ethiopia might attempt to tackle Ras Dashen Terara, the highest peak in the range.
