Individuals do have an impact. If we had 1 billion people we would be ok. But we have 7 billion. We literally got the overpopulation stage by having an impact. Our struggles are a direct effect of us. Without so many people, we would not need the companies that pollute the earth, we wouldn't need all the resources. We are the demand. Us being here directly causes services to exist which harms our earth. Having 25 grand children which leads to 60 great grand children, you've made a village that requires a village worth of resources. If you say you don't want companies to ruin the earth, then don't make children who give money and take resourced from said companies.
