What is a benefit of monoculture farming practices?

Rotation of monocultures (including cover crops ) disrupts pests, helps recycle nutrients, adds nitrogen (if legumes are used), shifts soil biology, and benefits yields of all the crops in the rotation.

What are the main causes of algae bloom?

The development and proliferation of algal blooms likely result from a combination of environmental factors including available nutrients, temperature, sunlight, ecosystem disturbance (stable/mixing conditions, turbidity), hydrology (river flow and water storage levels) and the water chemistry (pH, conductivity,

What happens after an algal bloom?

As more algae and plants grow, others die. This dead organic matter becomes food for bacteria that decompose it. With more food available, the bacteria increase in number and use up the dissolved oxygen in the water. When the dissolved oxygen content decreases, many fish and aquatic insects cannot survive.

What are the solution for deforestation?

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.
