What are the main ways of human activity to preserve the biosphere?

A person makes attempts to correct his own mistakes. Due to the anthropogenic factor, many ecological zones, ambient temperature, radiation levels and much more have been changed. This primarily threatens ourselves. The biosphere will be able to renew and recover. Three species of animals and plants disappear every hour without our “help”. Man tries to intervene in these processes and protects some species, creates reserves, prohibitions on hunting. But the main and most important thing is that they install treatment facilities that reduce the amount of emissions of hazardous substances into the biosphere.
