Environmental campaigners are hopeful of more protection for the Amazon rainforest after a change of government in Brazil.

Luiz Inácio da Silva - known as Lula - has been declared the winner of the Presidential elections there and is the county's new leader.

He defeated Jair Bolsonaro, who's been President since 2019.

Lula was also a familiar face to voters, having been president before, from 2003 to 2010 but lost power in part because of claims about corruption and allegations that he hadn't been following the rules.

Brazil is the largest country in South America and the fifth-largest nation by area in the world, home to over 214 million people.

This was an important election, not only for the Brazilian nation, but also for the rest of the world because the result is likely to have a big impact on the future of the Amazon rainforest and the global fight against climate change.

But voters will now be waiting to see if they can trust Lula to follow through on the promises he has made so far, particularly when it comes to his "aim for zero deforestation".

Why is the Amazon important?

The Amazon rainforest is the largest tropical rainforest in the world.

It is spread across nine countries in South America - Brazil, Peru, Colombia, Bolivia, Ecuador, French Guiana, Guyana, Suriname and Venezuela - but the majority of it, almost 60%, is in Brazil.

The huge rainforest is home to thousands of plants and wildlife species, many of which are only found in that part of the world.

It is also home to various species that are endangered and whose populations are under threat.

The Amazon is also very important in the world's fight against climate change. Scientists often call the rainforest the "lungs of the planet" because of the role it plays in absorbing carbon dioxide and producing oxygen.

The Amazon has been under increasing pressure recently with Brazil setting a new deforestation record earlier this year for the amount of trees cut down in the rainforest in one month.

Trees are important for our environment for many reasons: they absorb carbon, fight flooding, reduce pollution and help wildlife.

Deforestation is when forests are cleared for farmland, and the expansion of roads and cities, hunting of species and climate change - and all this has a negative impact on animal and plant species.

What has Lula said about the Amazon?

Both candidates have very different opinions on how Brazil should be run, including the future of the Amazon rainforest.

Luiz Inácio Lula da Silva has said he wants to increase protection measures for the Amazon and has promised to "aim for zero deforestation".

When he was in power previously his government managed to lower deforestation by 83% so people will be expecting him to match this at least.

He has said: "Instead of being world leaders in deforestation, we want to be world champions in facing up to the climate crisis and in socio-environmental development.

"That way we will have healthy food on our plates, clean air to breathe and water to drink and lots of quality jobs with green investment."

Jair Bolsonaro, has been accused of weakening environmental protection in Brazil.

According to government data from the country, deforestation increased by 75% over the years since he became President.

But President Bolsonaro argued that allowing more farming and mining in the Amazon would reduce poverty in the region as it gives poorer people more opportunities.

What is likely to happen next?

Deforestation has increased every year since Bolsonaro took power, so Lula's plan will be to quickly end Bolsonaro's current policies that allowed ranchers and loggers to take advantage of the Amazon's natural resources.

A new law proposed by Bolsanaro to allow mining on indigenous areas won't now happen, but many will be looking to see what can be done to stop illegal mining from continuing to take place.

Lula has also said he is "open to international co-operation to protect the Amazon" but many people will be watching to see if he will follow through on what he has promised.
