Brazil is home to 60% of the Amazon and a unique biodiversity that requires a respectful approach. Seasonal climatic variations influence wildlife breeding cycles, nesting periods, and the fragility of ecosystems that must be preserved.

♻️ Sustainable travel tips

  • Water management: Save water during the dry season, use reusable bottles
  • Responsible waste: Avoid single-use plastics, respect the 'leave no trace' rule
  • Local transport: Prioritize buses and trains, offset domestic flights
  • Respect biodiversity: Maintain distance from wildlife, do not feed wild animals
  • Local guides: Choose certified guides, support community economy
  • Eco-friendly accommodations: Prefer ecolodges and committed pousadas

🏙️ Local sustainable initiatives

Brazil is developing innovative conservation programs: protection of the Amazon by indigenous communities, solar energy projects in the Northeast, marine preservation initiatives on the Atlantic coast, and reforestation programs in the Cerrado.
