The Amazon Cooperation Treaty Organization (ACTO) is a group of countries working together. Its main goal is to help the Amazon Basin grow in a way that protects its future. This means using its resources wisely so they last a long time. ACTO is also known by its Portuguese name, Organização do Tratado de Cooperação Amazônica (OTCA).
The countries that are part of ACTO are Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. All these countries have parts of the amazing Amazon rainforest within their borders.
How ACTO Started
The idea for ACTO began with the Amazon Cooperation Treaty (ACT). This important agreement was signed on July 3, 1978. It was later updated in 1998.
ACTO itself was created in 1995. Its purpose was to make sure the Treaty's goals were put into action. A main office, called the Permanent Secretariat, was set up in Brasília, Brazil, in 2002.
