Which of the following countries is the host country for 2016 World Environment Day?

Angola
The World Environment Day is observed every year on June 5 to raise global awareness to take positive environmental action to protect nature and the planet Earth. The 2016 theme is “Zero tolerance for the illegal trade in wildlife”. This year United Nations (UN) has called a worldwide campaign “Go Wild for Life” to take a strong action to curb the illegal trade of wildlife i.e. threatening the biodiversity of the planet Earth. This year, Angola is the host country, which has created strong commitments to combat wildlife crime by shutting down its domestic ivory trade and is taking action to stop smuggling over its borders.
