Since nature has been shown in so many studies to have a positive effect on our physical and mental health, it makes sense to support the protection, creating, and maintenance of our green spaces. 

The following have been tagged with a Level of Activism to help make it easier to work out how the action can be effective on a systematic level:

• Enjoy Nature (Level 1 Activism) Go out in nature to walk, ride, row, garden, create, take photos, or even engage in activism. Being in nature not only has positive effects on your wellbeing, but can help you appreciate what lives in your area, and notice any problems developing which may need to be reported or dealt with.

• Explore Nature with Friends and/or Family (Level 2 Activism) a great way to make lasting memories, form stronger bonds, and help share the wonders of nature with those who mean the most to you.

• Become a Certified Nature Therapist (Level 1-3 Activism)

• Support Citizen Science Projects (Level 3 Activism) - this can give you an excuse to go in nature while directly supporting the scientific data that can help protect our wild spaces.

• Advocate for Green Prescription (Level 3-4 Activism) especially if your country's health care system doesn't already utilize it. This may involve communicating with health insurance companies or your local/national government, depending on how the health care system in your country is conducted.

• Support Greenway & Greenbelt Initiatives (Level 4 Activism) A growing number of communities have created or are creating legislative protections for wild places that will benefit everyone. Nature or Wildlife Corridors, Community & National Parks are other important resources to create and protect.

Singapore

"Singapore spends $150 million per year ‘to develop scenery’ (0.6% of its national budget). As the third densest country in the world, its government has recognised the potential negative impact on mental health of living in urban environments and taken radical steps to reduce some of the harmful effects of city living. With an understanding that city dwellers are more stressed and depressed (extensive reviews of medical literature show a 21% increase in anxiety disorders, a 39% increase in mood disorders, and a double risk of schizophrenia in city dwellers), Singapore has embraced greenery in every aspect of its planning, with integrated parks and gardens in its shopping centres, hospitals and office blocks. Architects and developers are encouraged to include green walls, roof parks and vertical gardens into corporate and residential towers, with government grants to help fund the projects. As a result, Singapore is now considered one of the top ‘biophilic’ cities in the world, with its percentage of green space actually increasing, even as its population grows. The government considers access to green space a priority for its citizens, and its large botanical gardens (an Ionesco Heritage Site) is open 16 hours a day and free to visitors. It has set itself the ambitious goal of having 80% of people living within 400m of green space, and it is already at 70%. A new hospital close to the city centre is an excellent example of a simple biophilic design, which has invested in the known health benefits of nature: many of its rooms face inner luxuriant garden courtyards, dense with trees and shrubs, specifically chosen to attract birds and butterflies; plants are draped over balconies and there’s a huge pond, a medicinal garden, a walking path, and an organic vegetable garden on the roof." - https://www.doseofnature.org.uk/around-the-world1#Singapore
