Many people wore green and red and wanted to protect nature areas at the rally.

People sat on mats and held signs that said things like 'Forests are our family'.

More than 1,000 people were at the rally, based on pictures from above.

The rally had activities like writing postcards and singing. It started at 3:30pm and lasted for three hours.

A woman named Aznikah Nizar hoped the rally would make the government think about the plans again.

Aznikah said it's not too late to change the plans because they haven't started cutting down trees yet.

Once forests are gone, they can't come back.

People also talked about losing forests and natural spaces, and how the public can be involved in decisions.

The government said it would build houses at Sunset Way and Gillman Barracks after studying the environment and history.

The plans would cut down about 15 hectares of Maju Forest and 10 hectares of forest at Gillman Barracks.

The government has talked to people about the plans and is getting feedback.

A minister said the plans would be changed to keep more green spaces, but didn't say how much.

Originally, 40% of green spaces at Gillman Barracks and 35% at Maju Forest would be kept.

The government is still getting feedback and will finalize the plans soon.

The government will publish a report about the feedback and its responses.

A man named Luo Kai Yi thought there should be more discussion about the plans.

Luo Kai Yi said the conversation doesn't have to be just about yes or no, but about finding a balance.

Some politicians were at the rally, including members of the Workers' Party and the Progress Singapore Party.

An MP named Dennis Tan said he was at the rally to support people who care about the issue.

Dennis Tan said many people have spoken up about the plans and he's happy to see people care about green spaces.

There are still many questions to ask, and the government should keep listening to people.

Another MP, Jamus Lim, said people understand that there are trade-offs, but want to know more.

Jamus Lim said people aren't just talking about trade-offs, but about what they really care about.

An artist named Terence Tan came to the rally with his family. He wants to support young people who care about the environment.

Terence Tan hopes his daughter will still live in Singapore and wants to understand what young people care about.

Terence Tan said the conversation is missing a sense of feeling and understanding for young people's concerns.

The group that organized the rally said it was happy with the turnout and will keep advocating.

The group wants the government to pause the developments until it provides more information.

The group also wants stronger protections for nature spaces and more public participation in decisions.
