Nature will always balance itself out - absolutely true - but we might not be able to withstand that balance. Nature has got no issues, when the earth was nothing but a mass of rock with constant meteor showers - it was fine then, also it was fine when the first life started, it was also fine when dinosaurs went extinct. NATURE will adapt, to whatever happens - we won't. If humans disappear tomorrow - trust me the "mother nature" won't miss us one bit. By making an effort we aren't helping "nature" but ensuring survival of our species, specially our own kids (I got none) and theirs - we will be old enough by the time everything goes to hell to probably not care about our lives. Please look everywhere around us. Ice is melting, water level is rising, floods are abundant, ground water is disappearing, cyclones are getting more common, forest fires are the new bonfires, smog is the new fog, species are disappearing at an alarming rate. It is difficult to take a fresh breath!
Yes I agree when you as a single person changes nothing happens, but then look at it this way. A family of 4 avoiding single use plastics, completely, imagine how much plastic you save in your lifetime from going into the ocean. THINK! Imagine - if the whole country doesn't buy coke, bisleri etc etc, (I know bottled water could be the only option for many - but just hypothetically), imagine the impact on our contribution to single use plastic. I know GOVT. needs to enforce these policies. I understand that, but if there is no demand, supply will die automatically. We are responsible too - it is our demand of Coke, McDonalds, Pizza Hut that allows and incentivises these companies to be here.
I am not saying that everyone on this forum if they change the world will be a better place. NOPE. It won't be. I get that - but just look at the collective impact. Read about the village in Maharashtra that restored the water table in their region. A guy in Uttarakhand is helping villages clean up pine (slowly but steadily) and grow indigenous varieties of trees there. Small things - big impact. I grew up spending around 3 months a year in my village a remote place in Uttarakhand, to give you an idea, we had to go around a KM down the village to poop and get water from a natural spring that was around 10 minutes walk. Today - the streams are dry, snow rarely falls, forest fires each year, springs are dried up, nothing grows except pine, farming is impossible. So people leave. I haven't gone to my village since 2017 cause there is no water
You need to carry 20L water bottles so you can live there for a few days or go there during monsoons only, which becomes hazardous as there are landslides everywhere. That is the impact that we do not see.
I am doing nothing to fix it - so I am not holier than thou either, but I have seen what will eventually happen.
A lot of countries have put plans in place to stop single use plastic, have put plans in place to incentivise people to put renewable energy, the generation of solar electricity (like what happened in Northern Germany) will stop the requirement of new Hydel Power Plants, thermal power plants. Use of fossil fuels (we all use LPG, CNG & motor vehicles) is currently impossible for all of us to just give up on, but wherever we can make a small difference it will help - for your kids in the future, we will be gone. Every bottle of coke you buy - your kids will have to pay for to clean up or their kids.
