I am feeling that a lot of acts which harm our ecosystem, cause global warming and cause damage to other beings too. What things can I do to minimize the harm from my side? I try not to throw rubbish on street but that is only thing I know. I don’t have recycling bins where I live.
The old slogan “Reduce, Reuse, Recycle” is in priority order. Buy less stuff, and try to fully make use of used things before you buy new. In this vein, I saw a great rhyme posted at a children’s play center to encourage the kids to make efficient use of the craft supplies: “Use it up, wear it out, make it do, or do without.”
Try to reduce your day-to-day travel by living close to work/school/groceries/etc.
Eat less meat and dairy.
If you own your home, consider energy efficiency improvements like new windows or a more efficient HVAC system. If your home has a yard, don’t spray herbicides/pesticides, and plant things to support native insects and birds.
Advocate for dense zoning and walkable urban development in your city, and better public transit.
