Dolphins in Lisbon river show benefits of protecting nature
Delegates attending a U.N. conference in Lisbon next week might take inspiration for their efforts to protect the oceans by looking out of the venue's windows at Portugal’s longest river, where frolicking dolphins nowadays delight locals and tourists.
The number of dolphins swimming from the Atlantic into the mouth of the River Tagus at Lisbon has increased significantly in recent times as pollution has dropped.
"In the past 10 years, with the water improvement, we started seeing wildlife much more frequently," says local sailor and guide Bernardo Queiroz, who organizes trips to see bottlenose and common dolphins in the river.
He says, "We used to see (the dolphins) 10 times a year and now we have (them) 200 days a year."
Queiroz's tour business aims to create awareness about the importance and the benefits of nature preservation.
Senior officials and scientists from more than 120 countries are due to attend the five-day U.N. Ocean Conference in Lisbon starting Monday.
