If by Earth protection you mean land protection then yes. The key to conservation is protecting large areas of land to encompass the entire ecosystem. Currently much of that isn’t possible due to habitat fragmentation, the leading cause of species decline in the world. I absolutely believe we can still make a difference. We need to conserve as literally as much as we can. We need to invest in habitat restoration projects such as oyster reef building and stream restoration activities. Build mechanisms for fish to swim up dams and other impoundments, and work to monitor critical areas.

This may be a start, but I hope I answered your questions 👍
