Deforestation is due to clearing land for farming. More people will require more land for farming and more cleared forest. Ocean acidification is due partially to increasing temperatures (from whatever source), and the increase in deadzones is due to agricultural runoff. More people means more farming and more agricultural runoff. Wildlife habitat loss happens when people consume more of the land surface area, which is bound to happen with an increasing population.
Surely there are ways to increase farming productivity, prevent run-off and ocean pollution, better management of fish stocks, etc., but do you really think countries outside of North America and Western Europe will ever bother with such measures until the land is irreversibly damaged? I'd say you are delusional if you think the human population can continue to grow without destroying what is left of the natural world.
