👀All eyes on #COP29!

🌍Immediate #climateaction isn’t just needed; it’s essential. Impactful decisions are of utmost importance now.

✅We need concrete steps, not just promises, to protect our planet.

“Time is not on our side.”

Speaking to global leaders at the @UNFCC Climate Change Conference #COP29, Secretary-General @antonioguterres calls for a rapid acceleration of #ClimateAction in countries national plans or humanity will pay the price. https://t.co/Sb2hX623bS

@Olympics I’m sorry, what contribution? Greece didn’t just 'contribute', Greece invented the Olympic Games! The rest of the world is just along for the ride. Let’s give credit where it’s due, people, because #FactsMatter. #Paris2024 #ClosingCeremony

🌍On August 1st, we hit #EarthOvershootDay, using up our 2024 resources.

🌱Good news: we can #MoveTheDate.

Small actions like reducing waste, using public transport 🚌, and supporting sustainable products 🛒can make a big difference.
Collective efforts lead to real change! ♻️

[UN Environment Programme @UNEP]

This year, 1 August is #EarthOvershootDay. Unfortunately, that means humanity’s demand for ecological resources in a given year has exceeded what Earth can regenerate.

Discover why there is still time to ditch this trend and immediate action is crucial: https://t.co/B9gHuHjvGZ

Thanks to the advanced technology of @CopernicusEU satellites, researchers have gained insights into where #marinelitter is coming from & where it accumulates🌍

It's incredible to see how #spacetechnology can help us address such a critical issue for our oceans🌊

#CleanSeas

[EU Maritime & Fish @EU_MARE]

Good news: we can use satellites to find marine litter!

Bad news: there's a lot of it.

By using @CopernicusEU satellites currently in orbit, researchers managed to acquire an unprecedented view of the emissions and accumulation areas of marine litter.

🌍Happy #WorldEnvironmentDay!🌿

🌱Today, let's not just celebrate our beautiful planet but also pledge to protect & preserve it.

We only have one Earth, and it’s up to us to take care of it.

💪Every action, no matter how small, makes a difference.

#ForNature

[UNESCO @UNESCO]

Forests are vital to protect our climate.

Yet, we are losing them at record speed. Our future depends on how we treat our nature today.

#WorldEnvironmentDay serves as a reminder to take action #ForNature before it’s too late.

As we continue with 'business as usual,' heartbreaking💔stories like this⬇️will likely become the norm.

"In just 3 days, the state saw the amount of rain normally seen over 4 months."❗️

The #climatecrisis is happening now. Question is, what will we do about it?

💧New study alert!

😱A liter of bottled water may contain up to 240,000 detectable nanoplastics, posing health risks like GI disorders, birth defects, and more.

🚰Choose wisely and stay informed!

[Forbes @Forbes]

A new study found a liter of bottled water contains hundreds of thousands of nanoplastics, which experts believe may cause health risks like gastrointestinal disorders, birth defects and increased mortality. https://t.co/ghVTPR4BJT

[Greenpeace UK @GreenpeaceUK]

🚨 SHOCKING: @Dove are pumping out 12,000 highly polluting, impossible-to-recycle plastic sachets... EVERY MINUTE.

They say they care about 'Real Beauty'.

But @dove's plastic is causing 'Real Harm'.

[Yianna Papaioannou Sigalou @Yiabi]

❗️'#Microplastics are in salt, beer, fresh fruit & vegetables, and drinking water. Airborne particles can circle the globe in a matter of days & fall from the sky like rain.' So basically, everywhere. The question is:do we want them to be?🤔

🌍We cannot recycle our way out of #plasticpollution.

When virgin #plastic is too cheap to produce & #recycling schemes are too complex to understand, the annual plastic waste recycled is only 9%😱

The only way forward: plastic bans🙅

#ClimateAction

[Yianna Papaioannou Sigalou @Yiabi]

🛑#PlasticPollution won't stop unless we put an end to it.

Individual actions do count, but to genuinely combat #climatechange, coorporations need to change too🌍

🙅Stop supporting #plastic production as a consumer.

[Yianna Papaioannou Sigalou @Yiabi]

Why am I not shocked?🤔🤦‍♀️

Misinformation needs to stop🙅There IS a scientific consensus about #climatechange.

That is why #climateAction is important while we still have time!

Right before the #NewYear comes, here are 7 facts about #fastfashion.
Think twice before buying anything new. Small individual steps CAN and do make a difference. #beatplasticpollution #ClimateAction #SaveOurPlanet #plasticpollution

[Greenpeace International @Greenpeace]

#FastFashion is destroying the planet.

The volumes of clothes being made and consumed continue to increase.

Sharing, repairing and second-hand must become the new normal.

The toll of #FastFashion is high💵

Are we willing to pay the price? But most importantly, can we & the next generations afford it?👖👗🧥

This #BlackFriday & #CyberMonday think twice before ordering you next purchase. We owe it to🌍

“Fast fashion” is a pollutant, impacting land, rivers, seas and the air we breathe.
