The two agricultural practices that can lead to algal blooms are:
1. **Application of nutrients to crops** - The application of fertilizers, which often contain high levels of nitrogen and phosphorus, can run off into nearby water bodies and promote algal blooms.
2. **Animal waste accumulated in livestock production** - Animal waste contains nutrients that, when washed into water bodies, can also contribute to nutrient pollution and trigger algal blooms.
The other options may contribute to environmental degradation but are not directly linked to algal blooms as clearly as the two choices listed above.
