The world’s top decision-making body on the environment is meeting in Kenya’s capital this week to discuss how countries can work together to tackle environmental crises like climate change, pollution and loss of biodiversity.

The meeting in Nairobi is the sixth session of the United Nations Environment Assembly, and governments, civil society groups, scientists and the private sector are attending.

At the opening plenary at the U.N. Environment Programme headquarters in Nairobi on Monday, Leila Benali, the president of this year’s assembly, urged members to work toward making “a tangible difference to people’s lives.”
