Once healed, they release them back into the wild – something she says will be harder if there is a highway on their doorstep.
"From the moment of deforestation, there is a loss.
"We are going to lose an area to release these animals back into the wild, the natural environment of these species," she said.
"Land animals will no longer be able to cross to the other side too, reducing the areas where they can live and breed."
The Brazilian president and environment minister say this will be a historic summit because it is "a COP in the Amazon, not a COP about the Amazon".
The president says the meeting will provide an opportunity to focus on the needs of the Amazon, show the forest to the world, and present what the federal government has done to protect it.
But Prof Sardinha says that while these conversations will happen "at a very high level, among business people and government officials", those living in the Amazon are "not being heard".
The state government of Pará had touted the idea of this highway, known as Avenida Liberdade, as early as 2012, but it had repeatedly been shelved because of environmental concerns.
Now a host of infrastructure projects have been resurrected or approved to prepare the city for the COP summit.
Adler Silveira, the state government's infrastructure secretary, listed this highway as one of 30 projects happening in the city to "prepare" and "modernise" it, so "we can have a legacy for the population and, more importantly, serve people for COP30 in the best possible way".
Speaking to the BBC, he said it was a "sustainable highway" and an "important mobility intervention".
He added it would have wildlife crossings for animals to pass over, bike lanes and solar lighting. New hotels are also being built and the port is being redeveloped so cruise ships can dock there to accommodate excess visitors.
Brazil's federal government is investing more than $81m (£62m) to expand the airport capacity from "seven to 14 million passengers". A new 500,000 sq-m city park, Parque da Cidade, is under construction. It will include green spaces, restaurants, a sports complex and other facilities for the public to use afterwards.
