For half a century, wild animals in the world have become 69% less.

Since 1970, the world population of wild animals has decreased by 69%. Blame it on deforestation, ocean pollution and climate change. In general, wild animals on the planet become 2.5% less every year. Those in Latin America and the Caribbean have been hardest hit. There, over half a century, populations have declined by 94%. For example, pink river dolphins in the Brazilian Amazon have decreased by 65%. Their numbers dropped sharply between 1994 and 2016. According to WWF experts, nature is in a desperate situation and is being destroyed. The Fund encourages developed countries to spend more on programs to preserve the planet's biodiversity.
