Our ancestors' environment doeis not is the same as our environment nowadays.

Actually, we both know the reason.

These issues awere not farom yesterdayund in the past.

This is my best guess at what you meant to write.

But, how about the solving ofution to these problems?

Perhaps the people, like me and you doare not takeing care inof the samenvironment in the way as it needs to be.

So, are we all are the guilty?

Not correexactly.

Because tThe people who more pollute aremore are often those who have more money.

Figure with me,Consider that rich people have more money to spend.

On the another side, thoThese are the people who have more money to be consumisters.

Being consumist tThey buy stuff that are not actually necessary.

SoAfter, say, a couple of weeks later, they throw that away.

So yYou think that these rich people are justonly a minority piece in theis Earth, and would be necessary more than that to arrive inmore than the current number are needed to result in the pollution that we arnow have today.

Even thoughHowever, when more people buy stuff, more people also produce and much morestuff.

Producing a bunch of products creates more pollution.

Consequently, morwe have the green house effect and morecontinually rising temperatures.

And tThat is why you are reading this and sweating.

Environment

Our ancestors's environment doeis not is the same as nowadays.

The issues are not from yesterday.

I'm not quite sure what you mean here.

So, we all are the guilty?

Not correctly.

Because the people who more pollute more are those who have more money.

FigureThink through it with me, rich people have more money to spend.

On the another side, those are the people who have more money to be consumerist.

Being consumerist, they buy stuff that areis not necessary.

stuff = uncountable, so it uses "is"
But you could also say "they buy things that are not necessary."

So, a couple weeks later they throw thait away.

So you think that these rich people are just a minority piece ion the Earth and would be necessary more than that to arrive in pollution that we are today.

I think you are trying to say something like: So you think that these rich people are just a minority on the Earth and can't have resulted in the level of pollution that we have today.
Or more naturally: So you think that there aren't enough rich people to have resulted in the level of pollution that we have today.

Producing a bunch of products creates more pollution.
