You can indeed. But growing cotton has already resulted in environmental changes beyond my comprehension.
I guess the first step should be to adapt a habit of clothes repair
Dude, I live in the midwest USA. The number one crop in this area is dent corn: 40% goes into ethanol production, and 36% is used for animal feed

86% of the global livestock feed intake in dry matter consists of feed materials that are not currently edible for humans
But it also makes an important contribution to food security through the provision of high-quality protein and a variety of micronutrients – e.g. vitamin A, vitamin B-12, riboflavin, calcium, iron and zinc – that can be locally difficult to obtain in adequate quantities from plant-source foods alone
Just because they feed corn doesn’t mean it’s edible to humans, a lot of the corn grown is left to dry on the plant and then harvested. We do this so we don’t end up with another famine. Not saying corn is what we should be growing for that, but it’s a very easy and hardy plant.
