Question

"every effect must have a cause." (explain)

Answer 1

According to the Law of Cause andEffect, every effect must have a cause. In other words, everything that happens has a catalyst; everything that came into being has something thatcaused it.

Answer 2

Hi my friend! ^_^

correction, every effort*

==> The fundamental truth of our time is that this culture is killing the planet. We can quibble all we want — and quibble too many do — about whether it is killing the planet or merely causing one of the six or seven greatest mass extinctions in the past several billion years, but no reasonable person can argue that industrial civilisation is not grievously injuring life on Earth.  Given that fact, you’d think most people would be doing everything they can to protect life on this planet — the only life, to our knowledge, in the universe. Sadly, you’d be wrong.

please mark as brainliest!
