Significats de upwardly cascading en anglès

I suspect, rather, that a majority of upwardly cascading effects will be negative at any higher level of expression.

We must not view upwardly cascading effects as uniquely detrimental for species, but generally neutral or even positive at other levels.

But, by important contrast, species construct their equally powerful integrity and discreteness by different means that do not require such suppression of upwardly cascading effects.
