Hello. I am not a Buddhist, but I am someone with I think some religious OCD and I worry that my existence is negative toward the world. I care deeply for the environment and like to feed birds and plant native gardens to help pollinators and other native fauna and flora. Do these acts generate good karma?

Edit: I have realised that I am uneducated and my perception of karma is inaccurate to how it is viewed in Buddhism. I apologise for this. I am trying to educate myself more in Buddhism and I am reading more about this.
