What would you say to someone who believes their actions are too small to make a difference for the environment?

I would encourage them to act anyway, for the chance that they may be an example to follow.

It starts with each individual making the right decision ex. Donnot litter

If you think donating to the cause or supporting and "spreading awareness" about climate change on social media helps anything, then yes, your "actions" mean nothing. That's precisely because, they're not "actions". If you actually want to help the environment, posting on social media about how evil oil companies are won't solve the issue.

Go plant a tree. Make biochar. Sequester your own carbon by burning plant material and putting it in the soil where it's stored there for THOUSANDS of years.

So fundamentally, no. Your actions are not too sma…  Read morell. Everyone can DO something, but the ones who claim to be the biggest advocates (liberals mostly) would rather just post on social media how much they CARE about the environment and attempt to force the government to flush BILLIONS of tax dollars down the toilet towards a problem that doesn't even really exist (let alone be solved by money). That accomplishes nothing.

That they should try to make more groups like that

To be ambitious and make sure they’re being heard and do what they can to get active

We live in a huge society and all these small actions can contribute eventually to a bigger cause. Protecting the environment is like building a giant sandcastle with lot of little grains of sand.

dont give up even the smallest voices make a differance

i agree its true one person cant make a big difference

By taking responsibility for our own environmental impact and inspiring others to do the same, we can collectively work toward a healthier, more sustainable planet.
