development of students' environmental literacy

What ideas would you recommend for the implementation of extracurricular activities aimed at developing students' environmental literacy?

Trip to nature or some kind of intitute that provides education (museums), hiking, collecting myshrooms

Regular recycling at school, garbage collection in nature or town

Waste separation

Project-based teaching - topics like Water in your town or Pollution of water and air in your town.

Go on a hike, for example.

students will create an album in which they would insert photos of a certain place in their surroundings. it must be about places that are polluted in some way. I have been observing changes in this land for a long time. is the pollution getting worse? it is better? in the end, they would propose possible solutions, which they would have to elaborate in detail.

Maybe waste separation and recycling.

For example determine your Carbon footprint. Student can use a carbon footprint calculator.
