There is no way realistically that the world will be a better place in the next few years not even in the next 10 or even 15. The reason why I think that is because there are people that are going to ruin those goals because they either don't agree with the goals we're trying achieve like gender equality and climate change. Also it's just not realistic and it can take a very long time especially if people don't want to help or disagree.

Each person is different(that’s what makes us human) and they have different opinions/backgrounds/experiences that affected them differently than us. So if someone says something that appears ignorant or insensitive not realizing, someone could tell them how it was rude to them. And then that person can educate themselves and learn not to say things like that and educate other people
