This year's controversial COP 30 climate change summit hasn't even started, but it's already causing environmental damage.

A new four-lane highway cutting through tens of thousands of acres of protected Amazon rainforest is being built for the COP30 climate summit in the Brazilian city of Belém. It aims to ease traffic to the city, which will host more than 50,000 people - including world leaders - at the conference in November.

World leaders will be among the 50,000 people descending on the Brazilian city of Belem this November for the COP30 climate summit. Brazil is hailing it as historic—"a COP in the Amazon, not a COP about the Amazon.
