What are some positive ways in which humans interact with the environment?
This depends to some extent on what your definition of a "positive" interaction with the environment is. There are many people for whom building a dam would be a positive interaction with the environment because it would be a way of changing the environment to make it more convenient for people.
I imagine, though, that you are asking more about interactions that would help the environment or would at least not harm it. Some examples of such interactions would be:
- Hiking. When people go hiking in the woods or in some other natural area, they benefit and the environment is generally not harmed. The people get to interact with nature without doing anything serious to pollute or destroy it. This can have the added benefit of making people care about the environment and want to save it.
- Recycling. When people do this, they are helping the environment. They are making it so that not as many new resources will have to be extracted from the environment.
- Ecotourism. When people travel to see unspoiled environments, they give the residents of those areas incentives to conserve their natural environment. This makes the environment economically important to its residents and makes them more likely to save it rather than destroying it.
This is an interesting question, particularly since the environmental crisis we are now globally facing is one largely caused by destructive human behaviors (the stripping of land for resources, deforestation, drilling for oil, abuse of fossil fuels, the dumping of waste, air pollution, etc.).
However, human beings can positively contribute to the environment. Americans have created National Parks as a means of protecting lands and species, as well as providing people with the opportunity to experience the beauty of the natural world in a non-intrusive manner. We have developed ecotourism as a means of combating mass tourism and of creating incentives to conserve local ecosystems.
We now have the technology that allows us to reduce waste and our ecological footprint. We can participate in recycling programs which effectively reuse glass, plastics, and paper that would otherwise wind up in landfills. We can harvest rainwater in order to slow the depletion of natural aquifers and the depletion of water tables. We also may turn to renewable energy resources (like solar panels) in order to reduce the use of fossil fuels.
A positive interaction that humans have with the environment is saving animals that are endangered or injured. Unfortunately, not all humans are like this and sometimes we tend to hurt it, but there are many organizations out there that help animals heal when they cannot help themselves or might end up dead.
There are people out there who take care of orphaned baby animals. Without these people helping them, these babies are not able to survive in the wild.
The important thing is to educate people about how to make our world better instead of destroying it.
