Green planet

Fifty years ago thigs were really different. People didn't have to worry about pollution because there wasn't as much as there is now. There wasn't so many buildings in cities and people didn't use cars so often like we do now because it was very expensive. There was less technology so there was also less pollution.The only bad thing is that people didn't recycle like we do now and recycling helps a lot to the planet.
People didn't know pollution existed. Now, we have a lot of pollution problems but at least, we are aware of it and there are eco-friendly products, houses and even villages.
We have to protect our planet and care about it now that we have so much pollution.
