We can, and have, quite successfuly kill biodiversity without much science at all. Ex: all the megafauna of the americas was hunted to extinction by primitives with sticks ans stones.

i'm not saying that naturally processes don't cause extinctions, i'm saying that the processes we developed have caused far more extinctions than natural processes do and will continue to do so

The collapse of Mesopotamia is partly attributed to ignorance about irrigation. They basically poisoned their own fields by letting the mineral salts build up in the top layer of the soil. Humans are very capable of wiping themselves out.

Processes we developed have yielded far better results in sustaining farm land than without science.

A lot of extinctions have resulted from going about our ways without properly understanding how things work. Like spreading diseases, introducing plants and wildlife into new areas that can't cope with it. Over fishing, is that caused by science making fishing more efficient or by ignorance or willfully ignoring the impact on the ecosystem.

On one side science have decreased the number of infant deaths and lengthened our lifespan, yet it also provides ways and incentives to reduce birth rates. However religion is still perfectly fine to have you reproduce like rabbits. Over population is the biggest problem. Having 1 less kid will save the environment more than anything else you can possibly do.
