I congratulate you for the work done. It is extremely important that we take care of the environment so that future generations have the chance to enjoy this beautiful world healthily. I leave some tips to take care of the environment:
• Let's make the most of the light, with the changes in the schedule, it also helps us conserve more energy.
• Save more water, with actions such as washing the car with a bucket of water instead of using the hose will help us reduce consumption.
• Disconnect your electrical appliances when you are not using them, this will help them not consume even a minimum amount of electricity.
• Choose batteries that are recharged with solar energy.
• Avoid as much as you can use the car. Traveling by bicycle or public transport instead of the car will make you a healthier person and contribute to polluting less.
• Choose paper or cloth bags, since regular plastic bags are very polluting because they take more time to degrade.
• Plant trees, either in the garden, in a park or look for civil societies that are reforesting. All this helps to improve the air of the city and our lungs.

I hope it helps :)
